Intimate partner violence (IPV) victimization is linked to sexual risk exposure among women. However, less is known about the intersection of IPV perpetration and sexual risk behavior among men. This study used data from a diverse, community sample of 334 heterosexually active young men, aged 18 to 25, across the United States to examine whether and how men with distinct IPV-related behavior patterns differed in sexual risk–related behavior and attitudes. Participants were recruited and surveyed online, and grouped conceptually based on the types of IPV perpetration behavior(s) used in a current or recent romantic relationship. Groups were then compared on relevant sexual risk variables. Men reporting both physical abuse and sexual coercion against intimate partners reported significantly higher numbers of lifetime partners, higher rates of nonmonogamy, greater endorsement of nonmonogamy, and less frequent condom use relative to nonabusive men or those reporting controlling behavior only. This group also had higher sexually transmitted infection (STI) exposure compared to men who used controlling behavior only and men who used sexual coercion only. Findings suggest that interventions with men who use physical and sexual violence need to account for not only the physical and psychological harm of this behavior but also the sexual risk to which men may expose their partners.

Behaviors established during adolescence such as risky sexual behaviors have negative effects on future health and well-being. Extant literature indicated that individual attributes such as peer pressure and substance use have impacts on healthy development of young peoples' sexual behavior. The patterns of relationships (social network structure) and the social network content (members' norm regarding sexual practice) established by adolescents' network on adolescents' risky sexual behaviors are not well investigated. This cross-sectional study assessed the roles of social networks on sexual behavior of high school adolescents in Bahir Dar and Mecha district, North West Ethiopia. Data were collected from 806 high school adolescents using a pretested anonymously self administered questionnaire. Hierarchical logistic regression model was used for analysis. The results indicated that more than 13% had risky sexual behavior. Taking social networks into account improved the explanation of risky sexual behavior over individual attributes. Adolescents embedded within increasing sexual practice approving norm (AOR 1.61; 95%CI: 1.04 - 2.50), increasing network tie strength (AOR 1.12; 95% CI: 1.06 - 1.19), and homogeneous networks (AOR 1.58; 95% CI: .98 - 2.55) were more likely to had risky sexual behavior. Engaging within increasing number of sexuality discussion networks was found protective of risky sexual behavior (AOR .84; 95% CI: .72 - .97). Social networks better predict adolescent's risky sexual behavior than individual attributes. The findings indicated the circumstances or contexts that social networks exert risks or protective effects on adolescents' sexual behavior. Programs designed to reduce school adolescents' sexual risk behavior should consider their patterns of social relationships.

Sexual behavior that is "out of control": a theoretical conceptual approach.

PubMed

Bancroft, John

2008-12-01

At this stage of our knowledge, it seems reasonable to assume that out-of-control sexual behavior results from a variety of etiological mechanisms associated with different behavioral patterns that share Goodman's two key features of addictive behavior: (1) a recurrent failure to control the sexual behavior; and (2) continuation of the behavior despite harmful consequences. Any overriding definition relevant to clinical management seems premature until we better understand the various patterns and their likely determinants. The concepts of "compulsivity" and "addiction" may have explanatory value in some cases, but are not helpful when used as general terms for this class of behavior problem. Stein and colleagues suggested that, in these circumstances, we use the term "hypersexuality." In my opinion, out-of-control sexual behavior or "impulse control disorders" as proposed by Barth and Kinder are more appropriate nonspecific terms because they focus on the issue of control rather than on high levels of sexuality. A number of clinically relevant and researchable hypotheses need to be addressed in further research, which hopefully will lead to more etiologically or therapeutically relevant subcategories of out-of-control sexual behavior.

Weaponized sex: defensive pseudo-erotic aggression in the service of safety.

PubMed

Kluft, Richard P

2017-01-01

Problematic sexual behaviors are frequently encountered in the treatment of patients suffering Dissociative Identity Disorder and related forms of dissociative disorders. These may include unfortunate patterns of ready acquiescence or submission to overtly or potentially aggressive or sexual approaches/encounters, subtle and/or overt seductive signaling and behaviors, and even overt sexually provocative patterns of verbalizations and actions. This paper discusses the possibility that in some instances, sexual behavior has become weaponized; that is, deployed in circumstances under which assertiveness and/or aggression or other self-protective measures might be expected, probably because such behaviors were not within the range of the possible or were not understood as potentially successful for some victims of trauma. Clinical manifestations are described and discussed. An animal model in which sexual behaviors substitute for aggressive behaviors is described. A speculative hypothesis is offered, postulating that in some cases, such patterns in traumatized humans might represent an epigenetic response to exogenous trauma. Exploration of this model may lead to improved understandings and approaches to trauma victims who manifest such behavior, hopefully destigmatizing them further, facilitating reduction of their shame and guilt, and supporting their recoveries. Clinical interventions are suggested.

Purpose Although a number of studies have demonstrated an association between alcohol use frequency and sexual risk behavior, few have used longitudinal data. This study examined alohol use frequency in adolescence as a predictor of HIV sexual risk behavior in adulthood. Methods We collected data among 1368 participants in Colorado. During adolescence (Time 1), respondents were asked about the frequency of using alcohol during the previous 12 months. In adulthood (Time 2), the same respondents were asked about their sexual risk behavior during the previous 12 months. Sexual risk behavior items were used to construct an index, which was categorized to indicate low, medium and high risk study participants. The relationship between alcohol use patterns and risky sexual behavior was modeled using ordinal regression. Results Compared to individuals who drank no alcohol in the past 12 months at Time 1, the odds of being in a higher risk group of sexual behavior as opposed to a lower one at Time 2 were 1.56 (95% CI, 1.04-2.35) among those who drank 6-19 times. Similarly, the odds of being in a higher risk group relative to a lower one among those who drank ≥20 times or were 1.78 (95% CI, 1.05-3.02). Conclusion Alcohol use patterns in adolescence may be useful markers for programs that aim to prevent risky sexual behavior. Based on alcohol intake patterns, it may be possible to identify frequent alcohol users that need to be targeted with appropriate alcohol use and HIV risk reduction messages. PMID:23587785

Daily diary and other intensive longitudinal methods are increasingly being used to investigate fluctuations in psychological and behavioral processes. To inform the development of this methodology, we sought to explore predictors of and patterns in diary compliance and behavioral reports. We used multilevel modeling to analyze data from an online daily diary study of 371 gay and bisexual men focused on sexual behavior and substance use. We found that greater education and older age as well as lower frequency of substance use were associated with higher compliance. Using polynomial and trigonometric functions, we found evidence for circaseptan patterns in compliance, sexual behavior, and substance use, as well as linear declines in compliance and behavior over time. The results suggest potential sources of non-random patterns of missing data and suggest that trigonometric terms provide a similar but more parsimonious investigation of circaseptan rhythms than do third-order polynomial terms.

2011-01-01

Purpose Although the emergence of sexual expression during adolescence and early adulthood is nearly universal, little is known about patterns of initiation. Methods We used latent class analysis to group 12,194 respondents from Waves I and IV of the National Longitudinal Study of Adolescent Health (Add Health) into one of five classes based on variety, timing, spacing, and sequencing of oral-genital, anal, and vaginal sex. Multinomial logistic regression models, stratified by biological sex, examined associations between sociodemographic characteristics and class membership. Results Approximately half of respondents followed a pattern characterized predominately by initiation of vaginal sex first, average age of initiation of approximately 16 years, and spacing of one year or more between initiation of the first and second behaviors; almost one third initiated sexual activity slightly later but reported first experiences of oral-genital and vaginal sex within the same year. Classes characterized by postponement of sexual activity, initiation of only one type of behavior, or adolescent initiation of anal sex were substantially less common. Compared to White respondents, Black respondents were more likely to appear in classes characterized by initiation of vaginal sex first. Respondents from lower socioeconomic backgrounds were more likely to be in classes distinguished by early/atypical patterns of initiation. Conclusions A small number of typical and atypical patterns capture the emergence of sexual behavior during adolescence, but these patterns reveal complex associations among different elements of emerging sexuality that should be considered in future research.

To identify and describe homogenous classes of male college students based on their weight-related behaviors (e.g., eating habits, physical activity, and unhealthy weight control) and to examine differences by sexual orientation. Study design was a cross-sectional sample of 2- and 4-year college students. Study setting was forty-six 2- and 4-year colleges in Minnesota. Study subjects comprised 10,406 college males. Measures were five categories of sexual orientation derived from self-reported sexual identity and behavior (heterosexual, discordant heterosexual [identifies as heterosexual and engages in same-sex sexual behavior], gay, bisexual, and unsure) and nine weight-related behaviors (including measures for eating habits, physical activity, and unhealthy weight control). Latent class models were fit for each of the five sexual orientation groups, using the nine weight-related behaviors. Overall, four classes were identified: "healthier eating habits" (prevalence range, 39.4%-77.3%), "moderate eating habits" (12.0%-30.2%), "unhealthy weight control" (2.6%-30.4%), and "healthier eating habits, more physically active" (35.8%). Heterosexual males exhibited all four patterns, gay and unsure males exhibited four patterns that included variations on the overall classes identified, discordant heterosexual males exhibited two patterns ("healthier eating habits" and "unhealthy weight control"), and bisexual males exhibited three patterns ("healthier eating habits," "moderate eating habits," and "unhealthy weight control"). Findings highlight the need for multibehavioral interventions for discordant heterosexual, gay, bisexual, and unsure college males, particularly around encouraging physical activity and reducing unhealthy weight control behaviors. © 2016 by American Journal of Health Promotion, Inc.

Sex in Its Daily Relational Context.

2015-12-01

The present study measured the daily correlates of sexual behavior in an ecologically valid context by relying on a daily diary approach. Examining the dyadic and multicomponent nature of sexual behavior is essential to create valid models of sexual responding that are better aligned with the day-to-day context of having sex in a relationship. During 3 weeks, heterosexual couples completed, two times a day, an electronic diary to report on mood, own and perceived partner behavior, relational feelings (in the evening), sexual activity, physical intimacy, and masturbation (in the morning). This design allowed testing bidirectional temporal associations between daily context and different types of sexual behavior. Positive mood, displays of positive partner behavior, perceived positive partner behavior, and positive relational feelings predicted more sexual activity and intimacy in men, which then further increased their positive mood, perceived positive partner behavior, and positive feelings about the relationship on the following day. Women showed a similar pattern of predictors regarding sexual activity as men, though the effect of sexual behavior on next-day feelings and behavior was more relationship-oriented rather than affecting personal mood. Intimacy was related to almost all daily variables in women, but related only to own and perceived positive partner behavior and positive relational feelings the next day. Several partner effects also reached significance, and these were more influential in predicting male than female intimacy. Solitary sexual activity showed a different pattern of results than dyadic sexual activity, with men experiencing masturbation as negatively in the context of their relationship. These results confirm the regulatory function of sex and intimacy in maintaining a positive relational climate and indicate that the quality of the everyday relational context is important to get partners in the mood to act in a sexual way. © 2015 International Society for Sexual Medicine.

Adolescents' use of sexually explicit Internet material and their sexual attitudes and behavior: Parallel development and directional effects.

Although research has repeatedly demonstrated that adolescents' use of sexually explicit Internet material (SEIM) is related to their endorsement of permissive sexual attitudes and their experience with sexual behavior, it is not clear how linkages between these constructs unfold over time. This study combined 2 types of longitudinal modeling, mean-level development and cross-lagged panel modeling, to examine (a) developmental patterns in adolescents' SEIM use, permissive sexual attitudes, and experience with sexual behavior, as well as whether these developments are related; and (b) longitudinal directionality of associations between SEIM use on the 1 hand and permissive sexual attitudes and sexual behavior on the other hand. We used 4-wave longitudinal data from 1,132 7th through 10th grade Dutch adolescents (M(age) T1 = 13.95; 52.7% boys) and estimated multigroup models to test for moderation by gender. Mean-level developmental trajectories showed that boys occasionally and increasingly used SEIM over the 18-month study period, which co-occurred with increases in their permissive attitudes and their experience with sexual behavior. Cross-lagged panel models revealed unidirectional effects from boys' SEIM use on their subsequent endorsement of permissive attitudes, but no consistent directional effects between their SEIM use and sexual behavior. Girls showed a similar pattern of increases in experience with sexual behavior, but their SEIM use was consistently low and their endorsement of permissive sexual attitudes decreased over the 18-month study period. In contrast to boys, girls' SEIM use was not longitudinally related to their sexual attitudes and behavior. Theoretical and practical implications of these gender-specific findings are discussed.

Bidirectional associations between alcohol use and sexual risk-taking behavior from adolescence into young adulthood.

PubMed

O'Hara, Ross E; Cooper, M Lynne

2015-05-01

Overwhelming evidence indicates that sexual risk-taking behavior and alcohol use are linked, but the nature, strength, and timing of these relations may differ between gender and racial subgroups. These issues were addressed by examining the course and interrelations of both behaviors from adolescence into young adulthood, as well as how these patterns differed between both men and women and between Blacks and Whites. Data came from a representative, community-based sample of 1867 urban participants surveyed up to 5 times over a 15-year period. Although both prospective and trajectory analyses showed that adolescent involvement in one behavior predicted later involvement in the other, most patterns were moderated by gender, race, or both. In general, positive, bidirectional associations were discovered among men and Whites. Among women, adolescent sexual risk-taking behavior positively predicted later drinking, but not vice versa. For Blacks, adolescent alcohol use was inconsistently related to later sexual risk-taking behavior, and adolescent sexual risk-taking negatively predicted later alcohol use. Results suggest that associations between sexual risk-taking behavior and alcohol use are more complex than previously thought and that an adequate understanding of these links must account for both gender and racial differences.

Janssen, Erick; Goodrich, David; Petrocelli, John V; Bancroft, John

2009-08-01

The past few years have seen an increased awareness of the relevance of studying the role of sexual response, emotion, and traits such as sensation seeking and the propensity for sexual inhibition in risky sexual behavior. The current study examined the association between self-reported sexual risk taking and psychophysiological response patterns in 76 heterosexual and homosexual men. Measures included genital, electrodermal, startle eyeblink, and cardiovascular responses, and stimuli included threatening (depicting coercive sexual interactions) and nonthreatening (depicting consensual sexual interactions) sexual film excerpts. Sexual risk taking was hypothesized to be associated with decreased inhibition of sexual arousal and hyporeactive affective and autonomic responses to threatening sexual stimuli. Controlling for age and number of sexual partners in the past year, sexual risk taking (number of partners during the past 3 years with whom no condoms were used) was found to be associated with stronger genital responses and smaller eyeblink responses to both threatening and nonthreatening sexual stimuli. Correlations between genital and subjective sexual arousal were relatively low. Sexual risk taking was related to sensation seeking but not to the propensity for sexual inhibition. The findings suggest that risky sexual behavior may involve a role for psychophysiological mechanisms that are specific to sex as well as for ones that are associated with more general approach/avoidance response tendencies.

In recent years, more adolescents are engaging in premarital sex in China. However, only a limited number of studies have explored out-of-school youth's sexual attitudes and behaviors, critical for prevention intervention development. Using data from the baseline survey of a comprehensive sex education program that was conducted in a suburb of Shanghai in 2000-2002, this study describes sexual attitudes, patterns of communication on sexual matters, and premarital sexual behavior among 1,304 out-of-school youth. Multivariate logistic regression analysis was conducted to examine the factors associated with youth's premarital sexual intercourse. The majority (60%) of out-of-school youth held favorable attitudes towards premarital sex. Males were more likely to have favorable attitudes compared with females. Male youth generally did not communicate with either parent about sex, while one-third of female youth talked to their mothers about sexual matters. Both males and females chose their friends as the person with whom they were most likely to talk about sexual matters. About 18% of the youth reported having engaged in sexual intercourse. One-fifth of sexually active youth had always used a contraceptive method, and one-quarter had been pregnant (or had impregnated a partner). There were no gender differences in rate of premarital sex or frequency of contraceptive use. Multivariate analysis revealed that age, education, family structure, parent's discipline, attitudes towards premarital sex, pattern of communication and dating were significantly associated with youth premarital sex. A substantial proportion of out-of-school youth engage in risky sexual behaviors. Prevention programs that empower communication and sexual negotiation skills, and promote condom use should be implemented for this vulnerable group.

Childhood Sexual Abuse in Adolescents Adjudicated for Sexual Offenses: Mental Health Consequences and Sexual Offending Behaviors.

PubMed

Morais, Hugo B; Alexander, Apryl A; Fix, Rebecca L; Burkhart, Barry R

2018-02-01

Most studies on the mental health consequences of childhood sexual abuse (CSA) focus predominantly on CSA survivors who do not commit sexual offenses. The current study examined the effects of CSA on 498 male adolescents adjudicated for sexual offenses who represent the small portion of CSA survivors who engage in sexual offenses. The prevalence of internalizing symptoms, parental attachment difficulties, specific sexual offending behaviors, and risk for sexually offending were compared among participants with and without a history of CSA. Results indicated that participants with a history of CSA were more likely to be diagnosed with major depression and posttraumatic stress disorder than those who did not report a history of CSA. A history of CSA was also positively correlated with risk for sexually offending and with specific offense patterns and consensual sexual behaviors. No significant differences emerged on parental attachment difficulties. These results highlight that adolescents adjudicated for sexual offenses with a history of CSA present with differences in sexual and psychological functioning as well as markedly different offending patterns when compared with those without a CSA history. Clinical implications and future directions are discussed.

Alcohol use, liberal/conservative orientations, and ethnicity as predictors of sexual behaviors.

PubMed

Neff, J A; Burge, S K

1995-03-01

The present study examined relationships among ethnicity, gender, alcohol consumption, and sexual behaviors in a community survey sample of 1,392 adults. Predictors included liberal versus conservative orientations (sex role orientation, religiosity); traditional versus liberal attitudes regarding sexuality, typical alcohol consumption patterns, expectancies regarding alcohol's effect upon one's sexuality, and frequency of alcohol use before sex. Findings are consistent with other studies indicating more sex partners among males than females and among Blacks (particularly males) than Anglos. Blacks also reported less involvement in oral sex than Anglos and Mexican-Americans--although observed differences for oral sex were more characteristic of females and less characteristic of unmarried nondrinkers. Unmarried Mexican-American males reported somewhat, though not significantly, more partners than did Anglos. Unmarried Black males (particularly nondrinkers) also reported more frequent risky behaviors than did Anglos. Divorced Black female drinkers reported significantly less frequent risky behavior than their Anglo counterparts. Alcohol use-sexual relationships were independent of psychosocial background characteristics and situated drinking (drinking before sex) was more strongly related to sexual behavior dimensions than were general drinking patterns.

Adolescent sexual behavior is multidimensional, yet most studies of the topic use variable-oriented methods that reduce behaviors to a single dimension. In this study, we used a person-oriented approach to model adolescent sexual behavior comprehensively, using data from the National Longitudinal Study of Adolescent Health. We identified five latent classes of adolescent sexual behavior: Abstinent (39%), Oral Sex (10%), Low-Risk (25%), Multi-Partner Normative (12%), and Multi-Partner Early (13%). Membership in riskier classes of sexual behavior was predicted by substance use and depressive symptoms. Class membership was also associated with young adult STI outcomes although these associations differed by gender. Male adolescents' STI rates increased with membership in classes with more risky behaviors whereas females' rates were consistent among all sexually active classes. These findings demonstrate the advantages of examining adolescent sexuality in a way that emphasizes its complexity. PMID:24449152

Parenting styles and practices are suggested to be important predictors of adolescent sexual health, mostly in Europe and North America. Limited research has been conducted on these processes in Sub-Saharan Africa, which has different patterns of adolescent sexual behavior and family traditions. This study qualitatively explored parenting practices and styles associated with adolescent sexual health in Tanzania, with 12 adolescents and 12 parents of adolescents. The themes we identified from the data included parental monitoring, preventive, and punitive behaviors. Parents were reported to use mostly punitive behaviors to correct or prohibit sexual behavior; parents also set clear rules about appropriate sexual behavior (e.g., modesty and abstinence). Parents were also reported to closely monitor their adolescent children's friendships and sexual behavior to minimize sexual behavior. However, some parents also engaged in positive preventive practices aimed at protecting their adolescent children.

Aging and human sexual behavior: biocultural perspectives - a mini-review.

PubMed

Gray, Peter B; Garcia, Justin R

2012-01-01

In this mini-review, we consider an evolutionary biocultural perspective on human aging and sexuality. An evolutionary approach to senescence highlights the energetic trade-offs between fertility and mortality. By comparing humans to other primates, we situate human senescence as an evolutionary process, with shifts in postreproductive sexual behavior in this light. Age-related declines in sexual behavior are typical for humans but also highly contingent on the sociocultural context within which aging individuals express their sexuality. We briefly review some of the most comprehensive studies of aging and sexual behavior, both from the USA and cross-culturally. We frame these patterns with respect to the long-term relationships within which human sexual behavior typically occurs. Because sexuality is typically expressed within pair-bonds, sexual behavior sometimes declines in both members of a couple with age, but also exhibits sex-specific effects that have their roots in evolved sex differences.

2016-01-01

Objectives: We examine the associations between different patterns of sexual behavior and function and three indicators of subjective well-being (SWB) covering eudemonic, evaluative, and affective well-being in a representative sample of partnered older people. Method: Using data from a Sexual Relationships and Activities Questionnaire (SRA-Q) in Wave 6 of the English Longitudinal Study of Ageing, latent class analysis identified groups characterized by distinctive patterns of sexual behavior and function and then examined their link to SWB. Eudemonic SWB was measured using a revised 15-item version of the CASP-19, evaluative SWB using the Satisfaction With Life Scale, and affective SWB using the 8-item version of the Centre for Epidemiologic Studies-Depression scale. Results: Sexual behavior and function was best described by six classes among men and five classes among women. These ranged from high sexual desire, frequent partnered sexual activities, and few sexual problems (Class 1) to low sexual desire, infrequent/no sexual activity, and problems with sexual function (Class 5[women]/6[men]). Men and women who reported either infrequent/no sexual activity, or were sexually active but reported sexual problems, generally had lower SWB than those individuals identified in Class 1. Poorer SWB in men was more strongly associated with sexual function difficulties, whereas in women desire and frequency of partnered activities appeared more important in relation to SWB. Discussion: Within the context of a partnered relationship continuing sexual desire, activity and functioning are associated with higher SWB, with distinctive patterns for women and men.

Walsh, Jennifer L.; Senn, Theresa E.; Carey, Michael P.

2013-01-01

Objective Diverse forms of violence, including childhood maltreatment (CM), intimate partner violence (IPV), and exposure to community violence (ECV), have been linked separately with sexual risk behaviors. However, few studies have explored multiple experiences of violence simultaneously in relation to sexual risk-taking, especially in women who are most vulnerable to violent experiences. Methods Participants were 481 women (66% African American, Mage = 27 years) attending a publicly-funded STD clinic who reported on their past and current experiences with violence and their current sexual risk behavior. We identified patterns of experience with violence using latent class analysis (LCA) and investigated which combinations of experiences were associated with the riskiest sexual outcomes. Results Four classes of women with different experiences of violence were identified: Low Violence (39%), Predominantly ECV (20%), Predominantly CM (23%), and Multiply Victimized (18%). Women in the Multiply Victimized and Predominantly ECV classes reported the highest levels of sexual risk behavior, including more lifetime sexual partners and a greater likelihood of receiving STD treatment and using substances before sex. Conclusions Women with different patterns of violent experiences differed in their sexual risk behavior. Interventions to reduce sexual risk should address violence against women, focusing on experiences with multiple types of violence and experiences specifically with ECV. Additional research is needed to determine the best ways to address violence in sexual risk reduction interventions. PMID:23626921

This study investigates body image concerns and disordered weight- and shape-related behaviors across adolescence and young adulthood in males and how patterns vary by sexual orientation. Participants were 5,388 males from the U.S. national Growing Up Today Study. In 2001, 2003, and 2005 (spanning ages 15-20 years), participants reported sexual orientation, past-year desire for toned/defined muscles and concerns with weight and shape, and past-year binge eating, restrictive dieting, purging (vomiting or laxative use), and use of products to increase muscularity (e.g., creatine, steroids). Latent class analyses identified 2 patterns at ages 15-16 years and 3 patterns at 17-18 and 19-20 years: healthy (all ages; low body image concerns and weight- and shape-related behaviors; 54-74% of observations), muscle-concerned (ages 17-18 and 19-20; relatively high muscularity concern and product use; 18-21% of observations), and lean-concerned (all ages; relatively high weight and shape concern, dieting, and binge eating; 19-28% of observations). Latent transition analyses revealed that sexual minority males (i.e., mostly heterosexual, gay, and bisexual) were more likely than completely heterosexual males to be lean-concerned at ages 17-18 and 19-20 years and to transition to the lean-concerned class from the healthy class. There were no sexual orientation differences in odds of being muscle-concerned. Both heterosexual and sexual minority males are at risk for presenting body image concerns and weight- and shape-related behaviors that may have deleterious health consequences. Results suggest the need for screening for concerns and behaviors related to leanness and muscularity in early adolescence among all males, regardless of sexual orientation.

Background: Health risk behaviors in adolescents and youth such as smoking, alcohol, drug use, violence, suicide, and unprotected sexual behavior are issues of major public health concern. Addressing the relationship between sexual behavior and non-sexual risk behaviors will make a significant contribution to the design of effective intervention programs for this population of adolescents and unmarried youth. Methods: This cross-sectional study was conducted in three Asian cities with a common heritage of Confucian values: Hanoi, Shanghai and Taipei. Data were collected in 2006 from 17,016 youth aged 15-24 years residing in both urban and rural districts of the three settings. The relationships between sexual behavior and seven non-sexual risk behaviors among unmarried adolescents were examined using χ2 tests, logistic regression models, Cox regression models, and cluster analysis. Results: Sexual behavior was associated with seven non-sexual risk behaviors, especially with smoking, drinking, drug use and running away from home. In terms of the age at initiation of risk behaviors, smoking and drinking were usually initiated before sexual intercourse. Sexual behavior and non-sexual risk behaviors co-occurred in the high risk group in all three cities. Youth having the highest risk of sexual behavior were more likely to have the highest risk of nearly all non-sexual risk behaviors, with the exception of fighting in Hanoi, and gambling in Shanghai and Taipei. Conclusion: Sexual behavior among unmarried youth is correlated with non-sexual risk behaviors but with different patterns across the three settings. Interventions aimed at reducing unprotected sex generally focus only on the sexual behavior; however, considering the correlations found here between sexual and non-sexual risk behaviors, they should target multiple risk behaviors.

Human ecology and behavior and sexually transmitted bacterial infections.

PubMed Central

Holmes, K K

1994-01-01

The three direct determinants of the rate of spread of sexually transmitted diseases (STDs) are sexual behaviors, the mean duration of infectiousness, and the mean efficiency of sexual transmission of each STD. Underlying ecological and behavioral factors that operate through one or more of these direct determinants lie on a continuum, ranging from those most proximate back to those more remote (in time or mechanism) from the direct determinants. Most remote and least modifiable are the historical stages of economic development that even today conspicuously influence patterns of sexual behavior. Next are the distribution and changing patterns of climate, hygiene, and population density; the global population explosion and stages of the demographic transition; and ongoing changes in human physiology (e.g., menarche at younger age) and culture (e.g., later marriage). More proximate on the continuum are war, migration, and travel; and current policies for economic development and social welfare. Most recent or modifiable are technologic and commercial product development (e.g., oral contraceptives); circumcision, condom, spermicide, and contraception practices; patterns of illicit drug use that influence sexual behaviors; and the accessibility, quality, and use of STD health care. These underlying factors help explain why the curable bacterial STDs are epidemic in developing countries and why the United States is the only industrialized country that has failed to control bacterial STDs during the AIDS era.

The current study examined patterns of psychopathology, drug and alcohol use, and sexual behavior associated with childhood abuse and neglect in a high-risk sample of low-income African American girls seeking mental health treatment. Participants (N=177) were African American girls recruited from mental health clinics serving low-income communities in Chicago, IL and followed over six waves of data collection (T1-T6) reflecting early (mean age 14) to late (mean age 17) adolescence. Child abuse and neglect history was determined from adolescent and caregiver reports. Latent curve modeling examined patterns of internalizing and externalizing psychopathology, drug and alcohol use, sexual experience, and risky sexual behavior reported by girls and associations with reported child abuse and neglect. Overall, these trajectories indicated a decrease in internalizing and externalizing symptoms, stability of drug and alcohol use, and an increase in sexual experience and risky sexual behaviors over time. Child abuse and neglect was associated with increased internalizing symptoms and sexual experience at baseline and with externalizing symptoms and risky sexual behavior both at baseline and the final point. Child abuse and neglect was not significantly associated with alcohol or drug use. This study adds to the literature on the long-term consequences of child abuse and neglect by demonstrating patterns of psychopathology and risky behavior that persist over time in a high-risk group of girls with self or parent reported histories of abuse and neglect. Interventions that address externalizing problems and health risk behaviors may be of particular importance for this population. Copyright © 2015. Published by Elsevier Ltd.

One in five Latino men who have sex with men has experienced child sexual abuse. Although concerning in itself, child sexual abuse may increase an individuals' likelihood of depression and risk-taking in adult life, including engagement in HIV risk behaviors and alcohol and substance use. It is therefore urgent that researchers and practitioners better understand the long-term effects of child sexual abuse. We utilized logistic and linear regression to assess associations between child sexual abuse (operationalized as forced or coerced sexual activity before age 17) and depression, sexual behaviors, and drinking patterns in a sample of 176 adult Latino men who have sex with men from New York City. Over one-fifth (22%) of participants reported child sexual abuse. In multivariable models, participants with histories of child sexual abuse were significantly more likely than participants without such histories to screen for clinically significant depressive symptoms and heavy drinking and reported more anal sex acts, male sexual partners, and incidents of condomless anal intercourse in the previous three months. These findings confirm a high prevalence of child sexual abuse among Latino men who have sex with men and associations between child sexual abuse and adulthood depressive symptoms, high-risk alcohol consumption, and sexual risk behaviors. We recommend that providers who serve Latino men who have sex with men incorporate child sexual abuse screenings into mental health, HIV prevention, and substance use treatment programs, utilizing approaches that are inclusive of resilience.

Gender roles, sociosexuality, and sexual behavior among US Black women

This study examined the relationship between gender roles and sociosexuality (an individual difference variable describing attitudes about sexual permissiveness and promiscuity), and their predictive pattern of HIV-related sexual risk behaviors. A geographically diverse sample of 275 adult, heterosexual Black women (mean age = 33.60 years), participated in a self-administered survey. Significant relationships were found between feminine traits and sociosexuality, and between sociosexuality and four of the five risky sexual behavior variables. Neither masculine nor feminine gender roles were related to any risky sexual behavior variables. Sociosexuality emerged as an important correlate that requires further exploration of its relationship to the attitudes and behaviors of Black women, and its potential relationship to HIV risk-related sexual behavior. The need for more attention to psychosocial variables, and consideration of context, cultural norms, and values is discussed as an important undertaking in order to garner an accurate picture of sexual risk behavior.

To create a culture of safe practices, we need to understand how and under what conditions the public makes risky decisions about their health. Because risky sexual behaviors are known to be common in young adults, we investigated their decision making regarding sexual activities that could incur a high risk of HIV infection. Sixty young urban adults maintained journals for two weeks and were interviewed regarding condom use and sexual history. We characterized four patterns of condom use behavior: consistent (35.0%), inconsistent (16.7%), consistent to inconsistent (35.0%), and inconsistent to consistent (13.3%). Directionality of reasoning was analyzed in the explanations provided for condom use decisions. The consistent and inconsistent patterns were associated with data-driven heuristic reasoning, where behavior becomes automated and is associated with a high level of confidence in one’s judgment. In the other two patterns, the shift in behavior was due to a significant event that influenced a change in directionality to explanation-based reasoning. We discuss these results within the framework of identifying potentially high-risk groups for whom customized intervention strategies (such as computer-based educational programs) can be used to reduce risk, thereby creating a culture of safer sexual practices.

Sexual arousal and masculinity-femininity of women.

PubMed

Rieger, Gerulf; Savin-Williams, Ritch C; Chivers, Meredith L; Bailey, J Michael

2016-08-01

Studies with volunteers in sexual arousal experiments suggest that women are, on average, physiologically sexually aroused to both male and female sexual stimuli. Lesbians are the exception because they tend to be more aroused to their preferred sex than the other sex, a pattern typically seen in men. A separate research line suggests that lesbians are, on average, more masculine than straight women in their nonsexual behaviors and characteristics. Hence, a common influence could affect the expression of male-typical sexual and nonsexual traits in some women. By integrating these research programs, we tested the hypothesis that male-typical sexual arousal of lesbians relates to their nonsexual masculinity. Moreover, the most masculine-behaving lesbians, in particular, could show the most male-typical sexual responses. Across combined data, Study 1 examined these patterns in women's genital arousal and self-reports of masculine and feminine behaviors. Study 2 examined these patterns with another measure of sexual arousal, pupil dilation to sexual stimuli, and with observer-rated masculinity-femininity in addition to self-reported masculinity-femininity. Although both studies confirmed that lesbians were more male-typical in their sexual arousal and nonsexual characteristics, on average, there were no indications that these 2 patterns were in any way connected. Thus, women's sexual responses and nonsexual traits might be masculinized by independent factors. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

The antiandrogen treatment of sexual offenders has been shown to reduce the recidivism rate. The mechanism of action has been assumed to be through asexualization with its secondary effects on sexual behavior. This study shows that the mechanism may be more complex and may involve a differential effect on sexual arousal patterns. Treatment responses may differ in high and low plasma testosterone groups.

We examine the associations between different patterns of sexual behavior and function and three indicators of subjective well-being (SWB) covering eudemonic, evaluative, and affective well-being in a representative sample of partnered older people. Using data from a Sexual Relationships and Activities Questionnaire (SRA-Q) in Wave 6 of the English Longitudinal Study of Ageing, latent class analysis identified groups characterized by distinctive patterns of sexual behavior and function and then examined their link to SWB. Eudemonic SWB was measured using a revised 15-item version of the CASP-19, evaluative SWB using the Satisfaction With Life Scale, and affective SWB using the 8-item version of the Centre for Epidemiologic Studies-Depression scale. Sexual behavior and function was best described by six classes among men and five classes among women. These ranged from high sexual desire, frequent partnered sexual activities, and few sexual problems (Class 1) to low sexual desire, infrequent/no sexual activity, and problems with sexual function (Class 5([women])/6([men])). Men and women who reported either infrequent/no sexual activity, or were sexually active but reported sexual problems, generally had lower SWB than those individuals identified in Class 1. Poorer SWB in men was more strongly associated with sexual function difficulties, whereas in women desire and frequency of partnered activities appeared more important in relation to SWB. Within the context of a partnered relationship continuing sexual desire, activity and functioning are associated with higher SWB, with distinctive patterns for women and men. © The Author 2016.

Involvement in bullying and sexual harassment in adolescence is associated with a variety of internalizing, externalizing, and health-risk behaviors. Yet, the two behaviors are often studied independently. The current study examined how bullying and sexual harassment co-occur and whether social connections protected youth from risk patterns. The data for this study come from the 2013 Minnesota Student Survey (N = 121,311; 50% female, 74% White, 26% received free or reduced-price lunch; M age  = 14.9, SD = 1.3). Students reported on bullying and sexual harassment victimization and perpetration. Using latent class analysis, youth were classified into five patterns: High-Risk of All Forms of Victimization and Perpetration (7%), Relational and Cyberbullying Victimization (17%), Sexual Harassment Victimization and Perpetration (8%), Physical Bullying Perpetration (6%), and Low-Risk (62%). Compared to the low-risk class, the four other classes had lower levels of social connections, particularly with teachers and parents. Older youth (9th and 11th grade students) were at greater risk for the sexual harassment pattern, while younger youth (8th grade students) were at greater risk for bullying patterns. The results indicate that efforts to reduce bullying should also address sexual harassment and social connections with adults.

Previous evidence links substance use disorders (SUD) to STI/HIV risk and suggests that comorbid psychiatric disorders increase the probability to engage in sexual risk behaviors. This study had two aims: (1) to identify subgroups based on sexual risk behavior using a person-centered approach in a sample of substance users and (2) to measure the association of psychiatric and SUD with subgroup membership. We assessed 402 male adults with SUD, reporting sexual intercourse in the previous 12 months using the HIV-Risk Behavior Scale and the Mini International Neuropsychiatric Interview. Latent class analysis was performed to determine multidimensional patterns of sexual risk behaviors and multinomial logistic regression was utilized to associate classes with disorders. The three-class model showed the best fit, and the classes were labeled: Relationship-Based (31.34% of the sample), Condom-Based (39.55%), and Multiple Risks (29.10%). Controlling for age and marital status, major depressive disorders, antisocial personality disorder, and any psychiatric disorder were associated with the Multiple Risks class. Results stress the importance of developing a personalized assessment and counseling for sexual risk behaviors in individuals with SUD, particularly when they endorse criteria for comorbid psychiatric disorders. Future studies should focus on evaluating differential response to preventive interventions.

A longitudinal, mixed methods study of sexual position identity, behavior, and fantasies among young sexual minority men.

Recent evidence suggests that young sexual minority men's sexual position identities (e.g., "top," "bottom," "versatile") may be governed by dynamic influences. Yet, no study has prospectively examined whether, how, and why this aspect of sexual minority men's sexuality changes over time. Consequently, the present study investigated the extent to which young sexual minority men use sexual position identities consistently over time, typical patterns of position identity change, explanations given for this change, and the correspondence of changing sexual position identities with changing sexual behavior and fantasies. A total of 93 young sexual minority men indicated their sexual position identity, behavior, and fantasies at two assessment points separated by 2 years. Following the second assessment, a subset (n = 28) of participants who represented the various sexual position identity change patterns provided explanations for their change. More than half (n = 48) of participants changed their sexual position identity. Participants showed a significant move away from not using sexual position identities toward using them and a significant move toward using "mostly top." Changes in position identity were reflected, although imperfectly, in changes in sexual behavior and largely not reflected in fantasy changes. Participants offered 11 classes of explanations for their identity changes referencing personal development, practical reasons, changing relationships, and sociocultural influences. Previous investigations of sexual minority men's sexual position identities have not adequately attended to the possibility of the changing use of the sexual position categories "top," "bottom," and "versatile" across young adulthood. Results of the present study suggest the possibility of a more fluid, context-dependent use of these terms than previously documented.

Sexual behavior, drugs, and relationship patterns on a college campus over thirteen years.

Three samples of college students at a small New England liberal arts college received questionnaires regarding their sexual philosophies, behavior, relationship with most recent partner, self-perceived attractiveness, relationship with parents, use of drugs and alcohol, attitudes toward marriage and abortion, and other subjects. The college was sampled in 1974, 1979, and 1986. Sexual behavior increased dramatically from 1974 to 1979 and then decreased in 1986 to approximately where it was in 1974. The reason for this change, and findings regarding the relationships between sexual behavior and many of the variables cited above are discussed.

The current retrospective archival study investigated the patterns of normative sexualized behavior (NSB), problematic sexualized behavior (PSB), and sexual perpetration for three age cohorts of boys and girls in a high-risk child welfare sample. All children in the present sample had exhibited some form of PSB in the past. We hypothesized that the incidence rates (IR) of NSBs would increase linearly from the early childhood cohort (Ages 2/3-7) to the middle childhood cohort (Ages 8-11) to the preadolescence/adolescence cohort (Ages 12-17), for girls and boys. Although the base rate of sexual behaviors generally increases as children age, children tend to hide sexual behaviors starting at an early age. We therefore hypothesized that a concave quadratic trend would be evident for most PSBs. We further predicted that older children would have a greater incidence of PSB, as well as more victims, compared with younger children. We found the predicted upward linear trend for NSB for both girls and boys, with minimal IR differences between the early childhood and middle childhood cohorts. IRs were remarkably high and comparable across age groups for both boys and girls, with respect to the same three PSBs. For the two perpetration history variables, there was a concave effect, with girls and boys in the middle childhood cohort exhibiting the lowest IR. Results are explained in the context of previously established patterns of sexualized behavior, as well as the reporting of such behaviors. Copyright © 2016 Elsevier Ltd. All rights reserved.

To examine the effect of childhood abuses on adolescents' psychology and behaviors related to harmful dietary pattern. Anonymous questionnaire study on childhood abuses, adolescents' psychology and behaviors regarding their dietary patterns was conducted among 5141 students in 9 middle schools in 2 areas of Anhui province. Among 5141 students, 29.9% reported having severe childhood physical abuse, 64.8% having intermediate childhood physical abuse, 51.4% having mental abuse, 5.3% having physical contact sexual abuse and 24.5% having non-physical contact sexual abuse. In junior, senior middle schools and vocational schools, the incidence rate of severe childhood physical abuse, physical contact sexual abuse and non-physical contact sexual abuse among male students was higher than that among female students. In total, the incidence rate of childhood mental abuse among female students (53.1%) was higher than that among male students (49.8%) and with significant difference (chi2 = 5.484, P < 0.05). The incidence rate of 5 kinds of childhood abuses among junior middle school students was relatively low, and the incidence rate of intermediate childhood physical abuse and mental abuse was higher among senior middle school students. The incidence rate of 9 among the 11 kinds of psychology and behaviors related to harmful dietary pattern among female students in the middle schools and vocational schools was higher than that among male students. By unconditional multivariate logistic regression model, results showed that the childhood abuses was among the 11 kinds of psychological and behavioral risk factors related to harmful dietary pattern. Childhood abuses had negative effects on dietary behaviors in adolescents.

Impulsivity is frequently included as a risk factor in models of adolescent sexual risk-taking; however, findings on the magnitude of association between impulsivity and risky sexual behavior are variable across studies. The aims of the current meta-analysis were to examine (1) how specific impulsivity traits relate to specific risky sexual behaviors in adolescents, and (2) how the impulsivity-risky sex relationship might differ across gender, age, and race. Eighty-one studies were meta-analyzed using a random effects model to examine the overall impulsivity-risky sex relationship and relationships among specific impulsivity traits and risky sexual behaviors. Overall, results revealed a significant, yet small, association between impulsivity and adolescent risky sexual behavior (r=0.19, p<0.001) that did not differ across impulsivity trait. A pattern of stronger effects was associated with risky sexual behaviors as compared to negative outcomes related to these behaviors. Gender moderated the overall relationship (β=0.22, p=0.04), such that effect sizes were significantly larger in samples with more females. Age, race, study design, and sample type did not moderate the relationship, although there was a pattern suggesting smaller effects for adolescents in juvenile detention settings. Adolescent samples with more females showed a larger impulsivity-risky sex relationship, suggesting that impulsivity may be a more important risk factor for risky sex among adolescent females. Research and treatment should consider gender differences when investigating the role of impulsivity in adolescent sexual risk-taking. Copyright © 2014 Elsevier Ltd. All rights reserved.

Understanding multiple levels of norms about teen pregnancy and their relationships to teens' sexual behaviors.

2014-06-01

Researchers seeking to understand teen sexual behaviors often turn to age norms, but they are difficult to measure quantitatively. Previous work has usually inferred norms from behavioral patterns or measured group-level norms at the individual level, ignoring multiple reference groups. Capitalizing on the multilevel design of the Add Health survey, we measure teen pregnancy norms perceived by teenagers, as well as average norms at the school and peer network levels. School norms predict boys' perceived norms, while peer network norms predict girls' perceived norms. Peer network and individually perceived norms against teen pregnancy independently and negatively predict teens' likelihood of sexual intercourse. Perceived norms against pregnancy predict increased likelihood of contraception among sexually experienced girls, but sexually experienced boys' contraceptive behavior is more complicated: When both the boy and his peers or school have stronger norms against teen pregnancy he is more likely to contracept, and in the absence of school or peer norms against pregnancy, boys who are embarrassed are less likely to contracept. We conclude that: (1) patterns of behavior cannot adequately operationalize teen pregnancy norms, (2) norms are not simply linked to behaviors through individual perceptions, and (3) norms at different levels can operate independently of each other, interactively, or in opposition. This evidence creates space for conceptualizations of agency, conflict, and change that can lead to progress in understanding age norms and sexual behaviors.

Changing patterns of adolescent sexual behavior: consequences for health and development.

Friedman, H L

1992-07-01

Sexuality is a fundamental quality of human life, important for health, happiness, individual development, and indeed for the preservation of the human race. During the dynamic period of adolescence in which the passage from childhood to maturity takes place, sexuality takes on new dimensions; feelings become more intense, relationships become more complex, and the consequences of sexual behavior are radically altered. This not only affects the behavior of young people but also of those who interact with them, their families and peers, and those who work in the health, education, youth, social welfare, and other sectors. In the contemporary world the conditions of life for many young people have also changed, and with it patterns of sexual behavior. In general, earlier puberty, later marriage, a decline in the family leading to less control and more autonomy, and intense exposure to sexual stimuli via the mass media and travel across cultural boundaries have made pre-marital adolescent sexual activity more common. This has added to traditional problems of early marriage, newer problems of early pregnancy, childbirth, and induced abortion outside of marriage, sexually transmitted diseases, and human immunodeficiency syndrome infection leading to acquired immunodeficiency syndrome. But the work of the World Health Organization (WHO), along with many others in the field, strongly suggests that given appropriate information and services, trust and equity between the sexes, young people will behave responsibly and well. In this paper some of the findings from methods developed by WHO for research, training, advocacy, and evaluation, and findings in relation to patterns and determinants of sexual and reproductive health and development will be described, and future directions suggested.

Effect of prepubertal versus postpubertal castration on sexual and aggressive behavior in male horses.

Males horses castrated prepubertally occasionally display stallion-like sexual and aggressive behavior as adults. A retrospective survey of 140 horse owners was undertaken to compare the effectiveness of prepubertal versus postpubertal castration on objectionable sexual and aggressive behavior. Of 94 geldings that had been castrated prepubertally (before 2 years of age), 20% to 30% displayed stallion-like sexual behavior and aggression toward horses, and 5% were aggressive toward people in a stallion-like manner. This occurrence of problem behavior was not significantly different from the occurrence of these behavioral patterns in 46 geldings that had been castrated as stallions (over 3 years of age). When castration was examined as a therapeutic measure to eliminate sexual and aggressive behavior in stallions in which the behavior had become objectionable, it was found that the operation was effective on sexual behavior and aggression toward people in 60% to 70% of horses and on aggression toward horses in 40% of horses.

The Double Standard at Sexual Debut: Gender, Sexual Behavior and Adolescent Peer Acceptance

A sexual double standard in adolescence has important implications for sexual development and gender inequality. The present study uses longitudinal social network data (N = 914; 11–16 years of age) to test if gender moderates associations between adolescents’ sexual behaviors and peer acceptance. Consistent with a traditional sexual double standard, female adolescents who reported having sex had significant decreases in peer acceptance over time, whereas male adolescents reporting the same behavior had significant increases in peer acceptance. This pattern was observed net of respondents’ own perceived friendships, further suggesting that the social responses to sex vary by gender of the sexual actor. However, findings for “making out” showed a reverse double standard, such that female adolescents reporting this behavior had increases in peer acceptance and male adolescents reporting the same behavior had decreases in peer acceptance over time. Results thus suggest that peers enforce traditional sexual scripts for both “heavy” and “light” sexual behaviors during adolescence. These findings have important implications for sexual health education, encouraging educators to develop curricula that emphasize the gendered social construction of sexuality and to combat inequitable and stigmatizing peer responses to real or perceived deviations from traditional sexual scripts.

2006-08-01

Patterns of sexually coercive behavior were examined among 266 Asian American and 299 European American men over 1 year. Noncoercer (n = 358), desister (n = 120), initiator (n = 39), and persistent (n = 48) sexually coercive groups were identified. The strongest predictor of sexual coercion was past sexual coercion. Persistent sexual coercers were higher than the other groups in delinquency and hostile masculinity and were nearly twice as likely to engage in laboratory sexual harassment. Loss of face attenuated self-reported sexual coercion and laboratory sexual harassment risk among Asian Americans and attenuated only laboratory sexual harassment risk among European Americans. These findings suggest that the heterogeneity of sexually coercive behavior and ethnicity are important research and clinical considerations.

Ethnic Variations in Prevalence of High-Risk Sexual Behaviors Among Asian and Pacific Islander Adolescents in Hawaii

Objectives. We examined ethnic variations in high-risk sexual behaviors among Asian and Pacific Islander (API) adolescents in comparison with White adolescents. Methods. We obtained data from the 2003 Hawaii Youth Risk Behavior Survey on 4953 students in grades 9 through 12. We conducted χ2 and logistic regression analyses on these data to examine the prevalence of high-risk sexual behaviors among Japanese, Filipino, Native Hawaiian, and White adolescents. Results. We found significant ethnic variation in prevalence of high-risk sexual behaviors among API adolescents. Relative to White adolescents, Native Hawaiian adolescents were most likely to engage in lifetime sexual intercourse, recent sexual intercourse, and sexual initiation before age 13 years; Japanese adolescents were least likely to engage in these behaviors. Filipino adolescents were least likely to use substances before last sexual intercourse and condoms during last sexual intercourse. Conclusions. Our findings suggest divergent patterns of risk among API ethnic groups, underscoring the heterogeneity of API subgroups and emphasizing the need for health disparities research on disaggregated API ethnic groups. The findings of such research should be used to design ethnically relevant interventions aimed at mitigating the negative health consequences of high-risk sexual behaviors. PMID:19106424

Our goal was to examine the prevalence, development, and persistence of drug and sex risk behaviors that place delinquent youth at risk for HIV and other sexually transmitted infections. At the baseline interview, HIV/sexually transmitted infection drug and sex risk behaviors were assessed in a stratified random sample of 800 juvenile detainees aged 10 to 18 years. Participants were reinterviewed approximately 3 years later. The final sample in these analyses (n = 724) included 316 females and 408 males; there were 393 African American participants, 198 Hispanic participants, 131 non-Hispanic white participants, and 2 participants who self-identified their race as "other." More than 60% of youth had engaged in > or = 10 risk behaviors at their baseline interview, and nearly two thirds of them persisted in > or = 10 risk behaviors at follow-up. Among youth living in the community, many behaviors were more prevalent at follow-up than at baseline. Among incarcerated youth, the opposite pattern prevailed. Compared with females, males had higher prevalence rates of many HIV/sexually transmitted infection risk behaviors and were more likely to persist in some behaviors and develop new ones. Yet, injection risk behaviors were more prevalent among females than males and were also more likely to develop and persist. Overall, there were few racial and ethnic differences in patterns of HIV/sexually transmitted infection risk behaviors; most involved the initiation and persistence of substance use among non-Hispanic whites and Hispanics. Because detained youth have a median stay of only 2 weeks, HIV/sexually transmitted infection risk behaviors in delinquent youth are a community public health problem, not just a problem for the juvenile justice system. Improving the coordination among systems that provide HIV/sexually transmitted infection interventions to youth--primary care, education, mental health, and juvenile justice--can reduce the prevalence of risk behaviors and substantially reduce the spread of HIV/sexually transmitted infection in young people.

HIV disproportionately affects African American men who have sex with men (MSM) in the United States. To inform this epidemiological pattern, we examined cross-sectional sexual behavior data in 509 African American MSM. Bivariate logistic regression analyses were conducted to examine the extent to which age, education,and sexual identity explain the likelihood of engaging in sex with a partner of a specific gender and the likelihood of engaging in unprotected sexual behaviors based on partner gender. Across all partner gender types,unprotected sexual behaviors were more likely to be reported by men with lower education. Younger, non-gay identified men were more likely to engage in unprotected sexual behaviors with transgender partners, while older, non-gay identified men were more likely to engage in unprotected sexual behaviors with women. African American MSM do not represent a monolithic group in their sexual behaviors, highlighting the need to target HIV prevention efforts to different subsets of African American MSM communities as appropriate.

A randomly selected cross-sectional survey was conducted with 880 youth (16 to 24 years) in Nha Trang City to assess relationships between alcohol consumption and sexual behaviors. A timeline followback method was employed. Chi-square, generalized logit modeling and logistic regression analyses were performed. Of the sample, 78.2% male and 56.1% female respondents ever consumed alcohol. Males reporting sexual behaviors (vaginal, anal, oral sex) had a significantly higher calculated peak BAC of 0.151 compared to 0.082 for males reporting no sexual intimacy (p < .0001). Females reporting sexual behaviors had a peak BAC of 0.072 compared to 0.027 for those reporting no sexual intimacy (p = .016). Fifty percent of (33/66) males and 30.4% (7/23) females report event specific drinking and engagement in sexual behaviors. Males reporting 11+ drinks in 30 days had more sexual partners than those reporting 1 to 10 drinks (p = .037). Data suggest different physical and psychosocial mediators between alcohol consumption and sexual behaviors by gender. PMID:21373363

Fruitless, doublesex and the genetics of social behavior in Drosophila melanogaster.

PubMed

Siwicki, Kathleen K; Kravitz, Edward A

2009-04-01

Two genes coding for transcription factors, fruitless and doublesex, have been suggested to play important roles in the regulation of sexually dimorphic patterns of social behavior in Drosophila melanogaster. The generalization that fruitless specified the development of the nervous system and doublesex specified non-neural tissues culminated with claims that fruitless was both necessary and sufficient to establish sex-specific patterns of behavior. Several recent articles refute this notion, however, demonstrating that at a minimum, both fruitless and doublesex are involved in establishing sexually dimorphic features of neural circuitry and behavior in fruit flies.

Preference for aggressive and sexual stimuli in children with disruptive behavior disorder and normal controls.

Children with disruptive behavior disorders (DBD) have poor social skills and show aggressive interaction patterns. There is evidence from prospective studies of an association between early physical abuse, later social information-processing patterns, and aggressive behavior. A pattern of hypervigilance to hostile cues has been found in DBD children, but very few studies have investigated encoding or perceptual preference for specific classes of stimuli. Some DBD children have a suspected history of sexual abuse and a few have themselves been sexually offensive. Our belief that the sexuality of DBD children should be investigated raised the issue of how to go about doing this. A procedure was developed in which we measured the relative preference for sexual and aggressive stimuli in comparison to other stimulus categories, and the data of DBD children were compared with those of normal controls. It was found that DBD children preferred viewing sexual slides and had a lower preference for nonaggressive slides. Furthermore, boys in general preferred viewing aggressive slides, did so for longer, and chose them earlier, whereas the more aggressive DBD children distinguished themselves in selecting aggressive stimuli earlier. The implications of these findings were discussed and it was concluded that sexuality is clearly an important topic to address in aggressive children in general and not only in the abused ones.

Sexual arousal and gaze behavior dynamics are used to characterize deviant sexual interests in male subjects. Pedophile patients and non-deviant subjects are immersed with virtual characters depicting relevant sexual features. Gaze behavior dynamics as indexed from correlation dimensions (D2) appears to be fractal in nature and significantly different from colored noise (surrogate data tests and recurrence plot analyses were performed). This perceptual-motor fractal dynamics parallels sexual arousal and differs from pedophiles to non-deviant subjects when critical sexual information is processed. Results are interpreted in terms of sexual affordance, perceptual invariance extraction and intentional nonlinear dynamics.

Sexual Experience in Female Rodents: Cellular Mechanisms and Functional Consequences

Meisel, Robert L.; Mullins, Amanda J.

2007-01-01

The neurobiology of female sexual behavior has largely focused on mechanisms of hormone action on nerve cells and how these effects translate into the display of copulatory motor patterns. Of equal importance, though less studied, are some of the consequences of engaging in sexual behavior, including the rewarding properties of sexual interactions and how sexual experience alters copulatory efficiency. This review summarizes the effects of sexual experience on reward processes and copulation in female Syrian hamsters. Neural correlates of these sexual interactions include long-term cellular changes in dopamine transmission and postsynaptic signaling pathways related to neuronal plasticity (e.g., dendritic spine formation). Taken together, these studies suggest that sexual experience enhances the reinforcing properties of sexual behavior, which has the coincident outcome of increasing copulatory efficiency in a way that can increase reproductive success.

Endocrine control of sexual behavior in teleost fish.

PubMed

Munakata, Arimune; Kobayashi, Makito

2010-02-01

Sexual behavior is one of the most profound events during the life cycle of animals that reproduce sexually. After completion of gonadal development that is mediated by various hormones, oviparous teleosts perform a suite of behaviors, often termed as spawning behavior. This is particularly important for teleosts that have their gametes fertilized externally as the behavior patterns ensures the close proximity of both sexes for gamete release, fusion and ultimately the production of offspring. As in other vertebrates, sexual behavior of fish is also under the control of hormones. Testicular androgen is a requirement for male sexual behavior to occur in most fish species that have been studied. Unlike tetrapods, however, ovarian estrogen does not appear to be essential for the occurrence of female sexual behavior for fish that have their gametes fertilized externally. Prostaglandins produced in the ovary after ovulation act as a trigger in some teleosts to induce female sexual behavior. Potentiating effects of gonadotropin-releasing hormone in the brain on sexual behavior are reported in some species. Under endocrine regulation, male and female fish exhibit gender-typical behavior during spawning, but in some fish species there is also some plasticity in their sexual behavior. Sex changing fish can perform both male-typical and female-typical sexual behaviors during their lifetime and this sexual plasticity can also be observed in non-sex changing fish when undergoing hormonal treatment. Although the neuroanatomical basis is not clear in fish, results of field and laboratory observations suggest that some teleosts possess a sexually bipotential brain which can regulate two types of behaviors unlike most other vertebrates which have a discrete sex differentiation of their brain and can only perform gender-typical sexual behavior.

Health risk behaviors in adolescents and youth, such as smoking, alcohol, drug use, violence, suicide, and unprotected sexual behavior, are issues of major public health concern. Addressing the relationship between sexual behavior and nonsexual risk behaviors will make a significant contribution to the design of effective intervention programs for this population of adolescents and unmarried youth. This cross-sectional study was conducted in three Asian cities with a common heritage of Confucian values: Hanoi, Shanghai, and Taipei. Data were collected in 2006 from 17,016 youth aged 15-24 years residing in both urban and rural districts of the three settings. The relationships between sexual behavior and seven nonsexual risk behaviors among unmarried adolescents were examined using χ(2) tests, logistic regression models, Cox regression models, and cluster analysis. Sexual behavior was associated with seven nonsexual risk behaviors, especially with smoking, drinking, drug use, and running away from home. In terms of the age at initiation of risk behaviors, smoking and drinking were usually initiated before sexual intercourse. Sexual behavior and nonsexual risk behaviors co-occurred in the high-risk group in all three cities. Youth having the highest risk of sexual behavior were more likely to have the highest risk of nearly all nonsexual risk behaviors, with the exception of fighting in Hanoi and gambling in Shanghai and Taipei. Sexual behavior among unmarried youth is correlated with nonsexual risk behaviors but with different patterns across the three settings. Interventions aimed at reducing unprotected sex generally focus only on the sexual behavior; however, considering the correlations found here between sexual and nonsexual risk behaviors, they should target multiple risk behaviors.

Population sexual behavior and HIV prevalence in Sub-Saharan Africa: missing links?

Patterns of sexual partnering should shape HIV transmission in human populations. The objective of this study was to assess empirical associations between population casual sex behavior and HIV prevalence, and between different measures of casual sex behavior. An ecological study design was applied to nationally representative data, those of the Demographic and Health Surveys, in 25 countries of Sub-Saharan Africa. Spearman rank correlation was used to assess different correlations for males and females and their statistical significance. Correlations between HIV prevalence and means and variances of the number of casual sex partners were positive, but small and statistically insignificant. The majority of correlations across means and variances of the number of casual sex partners were positive, large, and statistically significant. However, all correlations between the means, as well as variances, and the variance of unmarried females were weak and statistically insignificant. Population sexual behavior was not predictive of HIV prevalence across these countries. Nevertheless, the strong correlations across means and variances of sexual behavior suggest that self-reported sexual data are self-consistent and convey valid information content. Unmarried female behavior seemed puzzling, but could be playing an influential role in HIV transmission patterns. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Objectives. We examined the prevalence and associations between behavioral and identity dimensions of sexual orientation among adolescents in the United States, with consideration of differences associated with race/ethnicity, sex, and age. Methods. We used pooled data from 2005 and 2007 Youth Risk Behavior Surveys to estimate prevalence of sexual orientation variables within demographic sub-groups. We used multilevel logistic regression models to test differences in the association between sexual orientation identity and sexual behavior across groups. Results. There was substantial incongruence between behavioral and identity dimensions of sexual orientation, which varied across sex and race/ethnicity. Whereas girls were more likely to identify as bisexual, boys showed a stronger association between same-sex behavior and a bisexual identity. The pattern of association of age with sexual orientation differed between boys and girls. Conclusions. Our results highlight demographic differences between 2 sexual orientation dimensions, and their congruence, among 13- to 18-year-old adolescents. Future research is needed to better understand the implications of such differences, particularly in the realm of health and health disparities. PMID:24328662

The relation between sexual behavior and religiosity subtypes: a test of the secularization hypothesis.

PubMed

Farmer, Melissa A; Trapnell, Paul D; Meston, Cindy M

2009-10-01

Previous literature on religion and sexual behavior has focused on narrow definitions of religiosity, including religious affiliation, religious participation, or forms of religiousness (e.g., intrinsic religiosity). Trends toward more permissive premarital sexual activity in the North American Christian-Judeo religion support the secularization hypothesis of religion, which posits an increasing gap between religious doctrine and behavior. However, the recent rise of fundamentalist and new age religious movements calls for a reexamination of the current link between religion and sexual behavior. The use of dual definitions of religiosity, including religious affiliation and dimensional subtypes, may further characterize this link. The present cross-sectional study evaluated patterns of sexual behavior in a young adult sample (N = 1302, M age = 18.77 years) in the context of the secularization hypothesis using religious affiliation and a liberal-conservative continuum of religious subtypes: paranormal belief, spirituality, intrinsic religiosity, and fundamentalism. Results indicated few affiliation differences in sexual behavior in men or women. Sexual behaviors were statistically predicted by spirituality, fundamentalism, and paranormal belief, and the endorsement of fundamentalism in particular was correlated with lower levels of female sexual behavior. The secularization hypothesis was supported by consistent levels of sexual activity across affiliations and is contradicted by the differential impact of religiosity subtypes on sexual behavior. Findings suggested that the use of religious subtypes to evaluate religious differences, rather than solely affiliation, may yield useful insights into the link between religion and sexual behavior.

Reproductive behavior in male rodents is made up of anticipatory and consummatory elements which are regulated in the brain by sensory systems, reward circuits and hormone signaling. Gonadal steroids play a key role in the regulation of male sexual behavior via steroid receptors in the hypothalamus and preoptic area. Typical patterns of male reproductive behavior have been characterized, however these are not fixed but are modulated by adult experience. We assessed the effects of repeated sexual experience on male reproductive behavior of C57BL/6 mice; including measures of olfactory investigation of females, mounting, intromission and ejaculation. The effects of sexual experience on the number of cells expressing either androgen receptor (AR) or estrogen receptor alpha (ERα) in the primary brain nuclei regulating male sexual behavior was also measured. Sexually experienced male mice engaged in less sniffing of females before initiating sexual behavior and exhibited shorter latencies to mount and intromit, increased frequency of intromission, and increased duration of intromission relative to mounting. No changes in numbers of ERα-positive cells were observed, however sexually experienced males had increased numbers of AR-positive cells in the medial preoptic area (MPOA); the primary regulatory nucleus for male sexual behavior. These results indicate that sexual experience results in a qualitative change in male reproductive behavior in mice that is associated with increased testosterone sensitivity in the MPOA and that this nucleus may play a key integrative role in mediating the effects of sexual experience on male behavior.

Sexual activity among high-school-aged youths has steadily increased since the 1970s, emerging as a significant public health concern. Yet, patterns of youth sexual risk behavior are shaped by social class, race, and gender. Based on sociological theories of financial deprivation and collective socialization, we develop and test a model of the relationships among neighborhood poverty; family structure and social class position; parental involvement; prosocial activities; race; and gender as they predict youth sexual risk behavior. We employ structural equation modeling to test this model on a cross-sectional sample of 370 sexually active high-school students from a midwestern city; 57 percent (n = 209) are males and 86 percent are African American. We find that family structure indirectly predicts sexual risk behavior through neighborhood poverty, parental involvement, and prosocial activities. In addition, family class position indirectly predicts sexual risk behavior through neighborhood poverty and prosocial activities. We address implications for theory and health promotion.

In this article we examine how members of fishing communities on the shores of Lake Victoria in Uganda respond to HIV diagnosis in terms of disclosure to sexual partners. We then explore the subsequent changes in sexual behavior and relationships. To access this information, we collected life history data from 78 HIV-positive individuals in five fishing communities. We found that the strength of the sexual relationships shaped how and why individuals disclosed to partners, and that these relationships tended to be stronger when partners shared familial responsibility. Those who perceived their current sexual partnership to be weak sought to conceal their status by maintaining prediagnosis patterns of sexual behavior. The majority of the study's participants rarely changed their sexual behavior following HIV diagnosis, regardless of their relationship's strength. These findings elucidate barriers to disclosure and behavior change, and suggest that a life-course approach might enhance individual-level counseling so that counselors can provide tailored support to individuals regarding disclosure decisions and outcomes.

The impact of education on sexual behavior in sub-Saharan Africa: a review of the evidence.

Many studies have attempted to determine the relationship between education and HIV status. However, a complete and causal understanding of this relationship requires analysis of its mediating pathways, focusing on sexual behaviors. We developed a series of hypotheses based on the differential effect of educational attainment on three sexual behaviors. We tested our predictions in a systematic literature review including 65 articles reporting associations between three specific sexual behaviors -- sexual initiation, number of partners, and condom use -- and educational attainment or school enrollment in sub-Saharan Africa. The patterns of associations varied by behavior. The findings for condom use were particularly convergent; none of the 44 studies using educational attainment as a predictor reviewed found that more educated people were significantly less likely to use condoms. Findings for sexual initiation and number of partners were more complex. The contrast between findings for condom use on the one hand and sexual initiation and number of partners on the other supports predictions based on our theoretical framework.

Gender-based violence (GBV) is common among female sex workers (FSWs) and is associated with multiple HIV risk factors, including poor mental health, high-risk sexual behavior, and sexually transmitted infections (STIs). Prior studies have focused on GBV of one type (e.g. physical or sexual) or from one kind of perpetrator (e.g., clients or regular partners), but many FSWs experience overlapping types of violence from multiple perpetrators, with varying frequency and severity. We examined the association between lifetime patterns of GBV and HIV risk factors in 283 FSWs in Mombasa, Kenya. Patterns of GBV were identified with latent class analysis based on physical, sexual, or emotional violence from multiple perpetrators. Cross-sectional outcomes included depressive symptoms, post-traumatic stress disorder (PTSD) symptoms, disordered alcohol and other drug use, number of sex partners, self-reported unprotected sex, prostate-specific antigen (PSA) in vaginal secretions, and a combined unprotected sex indicator based on self-report or PSA detection. We also measured HIV/STI incidence over 12 months following GBV assessment. Associations between GBV patterns and each outcome were modeled separately using linear regression for mental health outcomes and Poisson regression for sexual risk outcomes. Lifetime prevalence of GBV was 87%. We identified 4 GBV patterns, labeled Low (21% prevalence), Sexual (23%), Physical/Moderate Emotional (18%), and Severe (39%). Compared to women with Low GBV, those with Severe GBV had higher scores for depressive symptoms, PTSD symptoms, and disordered alcohol use, and had more sex partners. Women with Sexual GBV had higher scores for disordered alcohol use than women with Low GBV, but similar sexual risk behavior. Women with Physical/Moderate Emotional GBV had more sex partners and a higher prevalence of unprotected sex than women with Low GBV, but no differences in mental health. HIV/STI incidence did not differ significantly by GBV pattern. The prevalence of GBV was extremely high in this sample of Kenyan FSWs, and different GBV patterns were associated with distinct mental health and sexual risk outcomes. Increased understanding of how health consequences vary by GBV type and severity could lead to more effective programs to reduce HIV risk in this vulnerable population.

The Human Research Council's National HIV Prevalence, Incidence and Behavior Survey ranks South Africa first in HIV incidence in the world with 400,000 new infections in 2012 and found the HIV incidence rate among female youth aged 15 to 24 years to be 2.5% that year. The objective of this study was to compare the pattern and predictability of sexual activity between HIV-infected and HIV-uninfected young South African women. Sexually active young women between the ages of 16 and 21 years old completed a study survey between October 2012 and 2014 at two Desmond Tutu HIV Foundation centers. 100 young women with a mean age of 19.04 years responded to the survey. 51 women (51%) were HIV-infected and 49 were HIV-uninfected (49%). HIV-infected young women were found to be statistically less likely to have a temporal pattern to their sexual activity as compared to HIV-uninfected young women (56.9 vs. 95.9%, p<0.0001). While controlling for frequency of sex and lifetime sexual partners, HIV status remains a significant predictor of having a pattern of sexual activity (OR=16.13, p=0.0004) and a predictor of having sex on the weekend only (OR=4.41, p=0.0022). The ability to predict when sexual activity will occur enables a woman to prepare for its associated risks. HIV-uninfected young women are more likely to have a predictable pattern to their sexual activity as compared to HIV-infected young women. Knowledge of the sexual behavior patterns of this high-risk population will aid in the development of effective HIV prevention campaigns.

Although a large body of previous research has examined sexual behavior and its relation to risk in men of diverse sexual identities, most studies have relied on convenience sampling. As such, the vast majority of research on the sexual behaviors of gay and bisexual men, in particular, might not be generalizable to the general population of these men in the United States. This is of particular concern because many studies are based on samples of men recruited from relatively "high-risk" venues and environments. To provide nationally representative baseline rates for sexual behavior in heterosexual, gay, and bisexual men in the United States and compare findings on sexual behaviors, relationships, and other variables across subgroups. Data were obtained from the 2012 National Survey of Sexual Health and Behavior, which involved the administration of an online questionnaire to a nationally representative probability sample of women and men at least 18 years old in the United States, with oversampling of self-identified gay and bisexual men and women. Results from the male participants are included in this article. Measurements include demographic characteristics, particularly sexual identity, and their relations to diverse sexual behaviors, including masturbation, mutual masturbation, oral sex, vaginal sex, and anal sex. Behaviors with male and female partners were examined. Men of all self-identified sexual identities reported engaging in a range of sexual behaviors (solo and partnered). As in previous studies, sexual identity was not always congruent for gender of lifetime and recent sexual partners. Patterns of sexual behaviors and relationships vary among heterosexual, gay, and bisexual men. Several demographic characteristics, including age, were related to men's sexual behaviors. The results from this probability study highlight the diversity in men's sexual behaviors across sexual identities, and these data allow generalizability to the broader population of gay and bisexual men, in particular, in the United States, which is a major advancement in research focused on individuals in a sexual minority.

Alcohol and risky sexual behavior among heavy drinking college students.

PubMed

Scott-Sheldon, Lori A J; Carey, Michael P; Carey, Kate B

2010-08-01

Multiple event-level methodology was used to examine the relation between risky sexual behavior and alcohol use among sexually active, heavy drinking college students (N = 221). Using a structured timeline follow-back interview, participants reported their sexual, alcohol, and drug use behaviors over a 3-month period. Over 2,700 vaginal or anal sexual events were reported from 177 participants. Overall, condom use was not associated with heavy or non-heavy alcohol consumption among those reporting both sexual events concurrent with heavy drinking and when no alcohol was consumed. Results from multilevel regression analyses revealed a more complex pattern. Among women, but not men, less condom use was associated with steady versus casual sexual partners, but partner type interacted with alcohol consumption such that less condom use occurred when heavy drinking preceded sex with steady partners. At the event-level, alcohol consumption among heavy drinking college students leads to risky sexual behavior but the relation differs by gender and partner type.

The purpose of this study was to examine the impact of several potential factors related to sexually risky behaviors in study abroad students. The authors utilized a pattern-centered analysis to identify specific groups that can be targeted for intervention. The sample consisted of 173 students who studied abroad in a variety of international locations for an average of 4 months. Participants completed questionnaires informed by the Triandis Theory of Interpersonal Behavior that have been predictive of risky sex in traditional traveling environments. The analyses revealed 3 different pathways for risky sexual behavior: Environmental involvement, historical condom use, and intentions to engage in risky sex. These findings can be used for identification of specific high-risk groups of students who can be targeted for predeparture prevention programs.

Toward a definition of "hypersexuality" in children and adolescents.

2012-09-01

Recent psychiatric literature has used the term "hypersexuality" to denote pathologically increased sexual behavior in children and adolescents. Various patterns of increased sexuality have been described in youth, including sexuality that is excessive, developmentally precocious, compulsive, aggressive, or otherwise socially inappropriate. Such "hypersexual" behavior in children and adolescents is associated with a variety of factors. Social factors include sexual abuse, physical abuse, life stress, and impaired family relationships. Psychiatric factors include emotional and behavioral problems in general, posttraumatic stress disorder and dissociative symptoms in particular, and possibly bipolar disorder. Despite the importance of increased sexual behavior in youth as a possible sign of these problems, there is currently no uniform definition in psychiatric literature of the term "hypersexuality" applied to children and adolescents. The usefulness of this term depends upon the degree to which it can be defined, measured, and distinguished from non-pathological juvenile sexual behavior. Research instruments are described that may be useful in measuring levels of sexual behavior in children and adolescents. Elements of a definition of juvenile hypersexuality are proposed based upon current knowledge about children and adolescents' sexuality in both normal development and a variety of conditions in which it is increased. Care is warranted in distinguishing between normal and abnormal sexual behavior in youth because of the variety of factors that can affect its measurement.

The association between sexual aggression and HIV risk behavior in heterosexual men.

Peterson, Zoë D; Janssen, Erick; Heiman, Julia R

2010-03-01

Perpetrating sexual coercion and rape can be conceptualized as a form of sexual risk taking. In this study, the authors evaluated the relationship between sexual aggression and other risky sexual behaviors (e.g., intercourse without a condom) using an online convenience sample of 1,240 heterosexual men. Sexually aggressive men engaged in more sexual risk taking (i.e., sex with multiple partners, unprotected sex, and one-night stands) than nonaggressive men, and almost half of the reported incidents of sexual aggression were unprotected (i.e., no condom was worn). Thus, sexual aggression was found to be part of a larger pattern of sexual risk taking. Regression analyses revealed that sexual aggression was associated with greater alcohol use and lower sexual inhibition-two variables that have consistently been found to be related to other forms of sexual risk taking.

Hormones orchestrate and coordinate human female sexual development, sexuality, and reproduction in relation to three types of phenotypic changes: life history transitions such as puberty and childbirth, responses to contextual factors such as caloric intake and stress, and cyclical patterns such as the ovulatory cycle. Here, we review the endocrinology underlying women's reproductive phenotypes, including sexual orientation and gender identity, mate preferences, competition for mates, sex drive, and maternal behavior. We highlight distinctive aspects of women's sexuality such as the possession of sexual ornaments, relatively cryptic fertile windows, extended sexual behavior across the ovulatory cycle, and a period of midlife reproductive senescence-and we focus on how hormonal mechanisms were shaped by selection to produce adaptive outcomes. We conclude with suggestions for future research to elucidate how hormonal mechanisms subserve women's reproductive phenotypes. Copyright © 2016 Elsevier Inc. All rights reserved.

Factors influencing the relationship between sexual trauma and risky sexual behavior in college students.

Johnson, Nicole L; Johnson, Dawn M

2013-07-01

While the relationship between sexual trauma and risky sexual behavior (RSB) has received much attention, only a handful of studies have investigated the factors that protect victims of sexual trauma from developing this maladaptive pattern of behavior. The current study investigated the protective role of social support, quality and quantity, in developing RSB, through the mechanism of problematic substance use. Two hundred and seventy-five female college students completed a series of self-reports assessing sexual trauma, problematic substance use, social support quality and quantity, and RSB. The results indicated a positive relationship between sexual trauma severity and RSB. Further, this relationship was mediated by participants' problematic substance use. Social support quality acted as a buffer against the relationship described above where quantity exacerbated this relationship. Implications will be discussed.

This study aimed at investigating sexual behavior patterns of elderly residents of urban areas in South Korea and their correlation with lower urinary tract symptoms. From May, 2009 to October, 2009, 154 males and 299 females over 60 years old who visited senior welfare centers of Seoul were administered a questionnaire on sex life patterns and voiding symptoms. Among the 154 males, 59 (38.3%) had sexual intercourse at least one time per month. The remaining 95 males (61.7%) did not have sexual intercourse, because of impotence for 52 males (52.6%), no sexual desire for 28 males (29.4%), and sex partner's problems for 15 males (15.7%). The higher International Prostate Symptom Score was, the lower International Index of Erectile Dysfunction-5 was (p=0.035). Among 299 females, 37 (12.4%) had sexual intercourse at least one time per month. The remaining 262 females (87.6%) did not have sexual intercourse, because of no spouse for 163 females (63.2%), no sexual desire for 48 females (18.6%), the spouse's impotence for 34 females (13.2%), and the spouse's bad health for 10 females (3.9%). It was found that self-diagnosis of overactive bladder affects sex life negatively. The sexual behaviors of the elderly included varying activity. Sexual intercourse were significantly associated with lower urinary tract symptoms. Our results suggest that the counseling with the elderly about sexual health is as important as it is with non-elderly individuals.

2017-11-20

This study used latent class analysis to identify patterns (i.e., classes) across a broad range of online sexual experiences among female adolescents (n = 312) and to explore offline sexual behavior and substance use correlates of as well as maltreatment differences in class membership. The following four classes were identified: Online Abstinent, Online Inclusive, Attractors, and Seekers. Maltreated female adolescents were more likely to be members of the Online Inclusive class and less likely to be members of the Online Abstinent class than nonmaltreated female adolescents. Offline sexual behaviors and substance use differentially predicted class membership. These results suggest online sexual experiences vary greatly and should not be aggregated together as a global risk factor for all female adolescents. © 2017 Society for Research on Adolescence.

Neural Substrates of Sexual Desire in Individuals with Problematic Hypersexual Behavior

Studies on the characteristics of individuals with hypersexual disorder have been accumulating due to increasing concerns about problematic hypersexual behavior (PHB). Currently, relatively little is known about the underlying behavioral and neural mechanisms of sexual desire. Our study aimed to investigate the neural correlates of sexual desire with event-related functional magnetic resonance imaging (fMRI). Twenty-three individuals with PHB and 22 age-matched healthy controls were scanned while they passively viewed sexual and nonsexual stimuli. The subjects' levels of sexual desire were assessed in response to each sexual stimulus. Relative to controls, individuals with PHB experienced more frequent and enhanced sexual desire during exposure to sexual stimuli. Greater activation was observed in the caudate nucleus, inferior parietal lobe, dorsal anterior cingulate gyrus, thalamus, and dorsolateral prefrontal cortex in the PHB group than in the control group. In addition, the hemodynamic patterns in the activated areas differed between the groups. Consistent with the findings of brain imaging studies of substance and behavior addiction, individuals with the behavioral characteristics of PHB and enhanced desire exhibited altered activation in the prefrontal cortex and subcortical regions. In conclusion, our results will help to characterize the behaviors and associated neural mechanisms of individuals with PHB. PMID:26648855

Sexual experience increases oxytocin receptor gene expression and protein in the medial preoptic area of the male rat.

Gil, Mario; Bhatt, Renu; Picotte, Katie B; Hull, Elaine M

2013-09-01

Oxytocin (OT) promotes social and reproductive behaviors in mammals, and OT deficits may be linked to disordered social behaviors like autism and severe anxiety. Male rat sexual behavior is an excellent model for OT regulation of behavior, as its pattern and neural substrates are well characterized. We previously reported that OT microinjected into the medial preoptic area (MPOA), a major integrative site for male sexual behavior, facilitates copulation in sexually experienced male rats, whereas intra-MPOA injection of an OT antagonist (OTA) inhibits copulation. In the present studies, copulation on the day of sacrifice stimulated OTR mRNA expression in the MPOA, irrespective of previous sexual experience, with the highest levels observed in first-time copulators. In addition, sexually experienced males had higher levels of OTR protein in the MPOA than sexually naïve males and first-time copulators. Finally, intra-MPOA injection of OT facilitated mating in sexually naive males. Others have reported a positive correlation between OT mRNA levels and male sexual behavior. Our studies show that OT in the MPOA facilitates mating in both sexually naive and experienced males, some of the behavioral effects of OT are mediated by the OTR, and sexual experience is associated with increased OTR expression in the MPOA. Taken together, these data suggest a reciprocal interaction between central OT and behavior, in which OT facilitates copulation and copulation stimulates the OT/OTR system in the brain.

Female homosexual behavior and inter-sexual mate competition in Japanese macaques: possible implications for sexual selection theory.

Vasey, Paul L; Leca, Jean-Baptiste; Gunst, Noëlle; VanderLaan, Doug P

2014-10-01

In this paper, we review research related to female homosexual behavior in Japanese macaques (Macaca fuscata), including our 20-year program of research on this species. Multiple lines of evidence indicate that female homosexual behavior in this species is sexually motivated. In contrast, many sociosexual hypotheses have been tested in relation to female homosexual behavior in Japanese macaques, but none have been supported. Female Japanese macaques sometimes engage in same-sex sexual activity even when motivated opposite-sex alternatives are available. Within this context of mate choice, males compete inter-sexually for opportunities to copulate with females above and beyond any intra-sexual competition that is required. Anecdotal evidence suggests that inter-sexual competition for female sexual partners has been observed in a number of other species, including humans. At present it is unclear whether inter-sexual competition for sexual partners influences patterns of reproduction. Our understanding of sexual selection and the evolution of mating systems may be improved by investigating whether inter-sexual mate competition influences the acquisition and maintenance of reproductive partners in those species in which such interactions occur.

Perceived verbal conflict behaviors associated with physical aggression and sexual coercion in dating relationships: a gender-sensitive analysis.

Katz, Jennifer; Carino, Andrew; Hilton, Angela

2002-02-01

We studied perceived partner verbal behaviors associated with participants' use of dating aggression. Men's reports of their partners' demanding, controlling, and psychologically abusive behaviors during conflicts were expected to predict men's perpetration against partners. In contrast, women's reports of their partners' withdrawal were expected to predict women's perpetration. Data were collected from heterosexual undergraduates (N = 223) in exclusive dating relationships. Participants' reports of partner demands and partner psychological abuse were associated with participants' use of physical aggression and sexual coercion. Reports of partner withdrawal and partner controlling behaviors were associated with participants' sexual coercion only. Significant moderating effects of gender emerged. As expected, partner demands, controlling behaviors, and psychological abuse were associated with physical aggression and sexual coercion in men, but not women. Partner withdrawal was associated with sexual coercion in both women and men. We conclude that gender-sensitive approaches are necessary to understand and prevent verbal conflict patterns associated with physical aggression and sexual coercion in intimate relationships.

This study assessed the utility of the Child Sexual Behavior Inventory (CSBI) in a child welfare sample. In this study, 97 children from ages 10 to 12 from either foster boarding homes or a residential treatment center participated. Researchers interviewed foster parents or primary therapists about children's sexual behavior, traumatic events, clinical symptoms, and their attitudes toward the child. Findings revealed that problematic sexualized behaviors were more prevalent in the residential treatment center (RTC) sample than they were in a normative sample. The pattern of associations between sexual behavior problems, traumatic events, and clinical syndromes in both the RTC and the foster boarding home (FBH) samples was similar to what has been found in samples in which biological custodial parents were the respondents. Analyses comparing youth who met the criterion for having problematic sexualized behaviors and youth who did not meet the criterion revealed that the two groups differed on clinical symptoms, prior traumatic events, and negative reports by caregivers. Results confirm the utility of the CSBI measure for this population and highlight several important clinical and programmatic concerns for addressing problematic sexual behavior in children in the child welfare system.

Is Young Adulthood a Critical Period for Suicidal Behavior among Sexual Minorities? Results from a US National Sample.

The developmental timing of suicide-related disparities between heterosexuals and sexual minorities (i.e., lesbian/gay and bisexual (LGB) people) is an understudied area that has critical prevention implications. In addition to developmentally situated experiences that shape risk for suicidality in the general population, sexual minorities also experience unique social stressors (e.g., anti-LGB stigma) that may alter their risk for suicidal behavior at different ages. Using a nationally representative US sample of adults, we assessed age-varying rates of suicidal behavior among heterosexuals and sexual minorities ages 18 to 60 and the age-varying association between anti-LGB discrimination and suicidal behavior. We also tested whether these age-varying prevalences and associations differed for men and women and for sexual minorities who did and did not endorse a sexual minority identity. Results indicate a critical period for suicide behavior risk for sexual minorities during young adulthood, with the highest rates of risk at age 18 followed by a steady decline until the early 40s. Disparities were particularly robust for sexual minorities who identified as lesbian, gay, or bisexual. This pattern was present for both men and women, though sexual minority women in their 30s were more likely to report suicidal behavior than heterosexuals and sexual minority men. Sexual minorities who experienced anti-LGB discrimination were more likely to report suicidal behavior, but the significance of this association was limited to those under 30. The effect of discrimination on suicidal behavior was stronger among young adult sexual minority men, relative to sexual minority women, but was present for a wider age range for sexual minority women (until age 30) relative to sexual minority men (until age 25).

Few data exist on the early sexual behavior patterns of contemporary young men who have sex with men (YMSM), the social context of these patterns, and which of these factors influence risk for HIV and other sexually transmitted infections (STI). We enrolled 94 YMSM (age 16-30) into a 1-year cohort study with serial online retrospective surveys and HIV/STI testing. The first three partnerships of YMSM were characterized by relatively high rates of unprotected anal sex and a rapidly expanding sexual repertoire, but also increasing rates of HIV status disclosure. During follow-up, 17 % of YMSM reported any nonconcordant unprotected anal intercourse (NCUAI) and 15 % were newly diagnosed with HIV/STI. Sex education in high school and current maternal support were protective against HIV/STI, while isolation from family and friends was associated with recent NCUAI. Social support-including from parents, peers, and school-based sex education-may help mitigate HIV/STI risk in this population.

Androphilia refers to attraction to adult males, whereas gynephilia refers to attraction to adult females. The current study employed self-report and viewing time (response time latency) measures of sexual attraction to determine the sexual orientation of Samoan cisgender men (i.e., males whose gender presentation and identity is concordant with their biological sex) who engage in sexual interactions with transgender male androphiles (known locally as fa'afafine) compared to: (1) Samoan cisgender men who only engage in sexual interactions with women, and (2) fa'afafine. As expected, both measures indicated that cisgender men who only engaged in sexual interactions with women exhibited a gynephilic pattern of sexual attraction, whereas fa'afafine exhibited an androphilic one. In contrast, both measures indicated that cisgender men who engaged in sexual interactions with fa'afafine demonstrated a bisexual pattern of sexual attraction. Most of the cisgender men who exhibited bisexual viewing times did not engage in sexual activity with both men and women indicating that the manner in which bisexual patterns of sexual attraction manifest behaviorally vary from one culture to the next.

Sexual behavior usually begins in adolescence, and is mediated by biological, personality and socio-cultural variables which can affect the expression of preventive and risky sexual performance, as well as sex and age differences. To determine sex differences in the age of sexual initiation, the use of protective methods and mate selectivity in young men and women, as well as preventive practices according to age, and the prevalence of partner aggression. Participants were 484 university students from public and private institutions, aged 22 ± 3 years (59% women) assessed using a diversity of self-report measures of personality traits, romantic relationship quality, sexual role, attachment type, socio-sexual openness, and self-esteem; they also answered questions regarding sexual behavior, and violence. Differences in age of sexual initiation, risky sexual behavior, and socio-sexual openness were observed between men and women. Aggression prevalence in romantic relationships also varied according to sex and age. Similarities and differences in patterns of behavior and personality variables were observed in relationship quality, sexual role, kindness, and responsibility in males and females. The findings present consistencies with the international evidence and differences that may be due to context specificities, providing also an empirical referent to consider in health planning.

Objective To determine the association between health-risk behaviors and a history of sexual coercion among urban Chinese high school students. Design A cross-sectional study was performed among 109,754 high school students who participated in the 2005 Chinese Youth Risk Behavior Survey. Data were analyzed for 5,215 students who had experienced sexual intercourse (1,483 girls, 3,732 boys). Multivariate logistic regression was used to determine the relationship between sexual coercion and the related covariates, and data were stratified by gender. Results Of those students who had had sexual intercourse, 40.9% of the females and 29.6% of the males experienced sexual coercion (p<0.01). When analyses controlled for demographic characteristics, in the study sample, that is, students who had sexual intercourse, drug use (odds ratios [OR], 2.44), attempted suicide (OR, 2.30), physical abuse (OR, 1.74), binge drinking (OR, 1.62), verbal abuse (OR, 1.29), experience of being drunk (OR, 0.68), and smoking of cigarettes (OR, 0.52) were related to a history of sexual coercion. Patterns of health-risk behaviors also differed among female and male students who had experienced sexual coercion. Conclusions Sexual coercion is associated with health-risk behaviors. Initiatives to reduce the harm associated with sexual coercion among high school students are needed. PMID:24836445

"Sexy stimulants": the interaction between psychomotor stimulants and sexual behavior in the female brain.

PubMed

Guarraci, Fay A; Bolton, Jessica L

2014-06-01

Research indicates gender differences in sensitivity to psychomotor stimulants. Preclinical work investigating the interaction between drugs of abuse and sex-specific behaviors, such as sexual behavior, is critical to our understanding of such gender differences in humans. A number of behavioral paradigms can be used to model aspects of human sexual behavior in animal subjects. Although traditional assessment of the reflexive, lordosis posture of the female rat has been used to map the neuroanatomical and neurochemical systems that contribute to uniquely female copulatory behavior, the additional behavioral paradigms discussed in the current review have helped us expand our description of the appetitive and consummatory patterns of sexual behavior in the female rat. Measuring appetitive behavior is particularly important for assessing sexual motivation, the equivalent of "desire" in humans. By investigating the effects of commonly abused drugs on female sexual motivation, we are beginning to elucidate the role of dopaminergic neurotransmission, a neural system also known to be critical to the neurobiology of drug addiction, in female sexual motivation. A better understanding of the nexus of sex and drugs in the female brain will help advance our understanding of motivation in general and explain how psychomotor stimulants affect males and females differently.

The Inevitability of Infidelity: Sexual Reputation, Social Geographies, and Marital HIV Risk in Rural Mexico

Marriage presents the single greatest risk for HIV infection among women in rural Mexico. We drew on 6 months of participant observation, 20 marital case studies, 37 key informant interviews, and archival research to explore the factors that shape HIV risk among married women in one of the country’s rural communities. We found that culturally constructed notions of reputation in this community lead to sexual behavior designed to minimize men’s social risk (threats to one’s social status or relationships), rather than viral risk and that men’s desire for companionate intimacy may actually increase women’s risk for HIV infection. We also describe the intertwining of reputation-based sexual identities with structurally patterned sexual geographies (i.e. the social spaces that shape sexual behavior). We propose that, because of the structural nature of men’s extramarital sexual behavior, intervention development should concentrate on sexual geographies and risky spaces rather than risky behaviors or identities.

Sexual identity and sex of sexual contacts can both be used to identify sexual minority youth. Significant health disparities exist between sexual minority and nonsexual minority youth. However, not enough is known about health-related behaviors that contribute to negative health outcomes among sexual minority youth and how the prevalence of these health-related behaviors compare with the prevalence of health-related behaviors among nonsexual minorities. September 2014-December 2015. The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-related behaviors among youth and young adults: 1) behaviors that contribute to unintentional injuries and violence; 2) tobacco use; 3) alcohol and other drug use; 4) sexual behaviors related to unintended pregnancy and sexually transmitted infections, including human immunodeficiency virus infection; 5) unhealthy dietary behaviors; and 6) physical inactivity. In addition, YRBSS monitors the prevalence of obesity and asthma and other priority health-related behaviors. YRBSS includes a national school-based Youth Risk Behavior Survey (YRBS) conducted by CDC and state and large urban school district school-based YRBSs conducted by state and local education and health agencies. For the 2015 YRBSS cycle, a question to ascertain sexual identity and a question to ascertain sex of sexual contacts was added for the first time to the national YRBS questionnaire and to the standard YRBS questionnaire used by the states and large urban school districts as a starting point for their YRBS questionnaires. This report summarizes results for 118 health-related behaviors plus obesity, overweight, and asthma by sexual identity and sex of sexual contacts from the 2015 national survey, 25 state surveys, and 19 large urban school district surveys conducted among students in grades 9-12. Across the 18 violence-related risk behaviors nationwide, the prevalence of 16 was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of 15 was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. Across the 13 tobacco use-related risk behaviors, the prevalence of 11 was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of 10 was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. Similarly, across the 19 alcohol or other drug use-related risk behaviors, the prevalence of 18 was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of 17 was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. This pattern also was evident across the six sexual risk behaviors. The prevalence of five of these behaviors was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of four was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. No clear pattern of differences emerged for birth control use, dietary behaviors, and physical activity. The majority of sexual minority students cope with the transition from childhood through adolescence to adulthood successfully and become healthy and productive adults. However, this report documents that sexual minority students have a higher prevalence of many health-risk behaviors compared with nonsexual minority students. To reduce the disparities in health-risk behaviors among sexual minority students, it is important to raise awareness of the problem; facilitate access to education, health care, and evidence-based interventions designed to address priority health-risk behaviors among sexual minority youth; and continue to implement YRBSS at the national, state, and large urban school district levels to document and monitor the effect of broad policy and programmatic interventions on the health-related behaviors of sexual minority youth.

The incidence of HIV infection in rural African youth remains high despite widespread knowledge of the disease within the region and increasing funds allocated to programs aimed at its prevention and treatment. This suggests that program efficacy requires a more nuanced understanding of the profiles of the most at-risk individuals. To evaluate the explanatory power of novel psychographic variables in relation to high-risk sexual behaviors, we conducted a survey to assess the effects of psychographic factors, both behavioral and attitudinal, controlling for standard predictors in 546 youth (12-26 years of age) across 8 villages in northern Tanzania. Indicators of high-risk sexual behavior included HIV testing, sexual history (i.e., virgin/non-virgin), age of first sexual activity, condom use, and number of lifetime sexual partners. Predictors in the statistical models included standard demographic variables, patterns of media consumption, HIV awareness, and six new psychographic features identified via factor analyses: personal vanity, family-building values, ambition for higher education, town recreation, perceived parental strictness, and spending preferences. In a series of hierarchical regression analyses, we find that models including psychographic factors contribute significant additional explanatory information when compared to models including only demographic and other conventional predictors. We propose that the psychographic approach used here, in so far as it identifies individual characteristics, aspirations, aspects of personal life style and spending preferences, can be used to target appropriate communities of youth within villages for leading and receiving outreach, and to build communities of like-minded youth who support new patterns of sexual behavior.

The purpose of this study is to describe patterns of care and service use among adolescent school-based health center (SBHC) users in New Mexico and contrast patterns and services between frequent and infrequent users. Medical claims/encounter data were analyzed from 59 SBHCs located in secondary schools in New Mexico during the 2011-2012 school year. We used Pearson's chi-square test to examine the differences between frequent (≥ 4 visits/year) and infrequent users in their patterns of SBHC care, and we conducted logistic regression to examine whether frequent use of the SBHC predicted receipt of behavioral, reproductive, and sexual health; checkup; or acute care services. Most of the 26,379 adolescent SBHC visits in New Mexico were for behavioral health (42.4%) and reproductive and sexual health (22.9%). Frequent users have greater odds of receiving a behavioral, reproductive, and sexual health; and acute care visit than infrequent users (p < .001). American Indians, in particular, have higher odds of receiving behavioral health and checkup visits, compared with other races/ethnicities (p < .001). SBHCs deliver core health care services to adolescents, including behavioral, reproductive, and checkup services, to high need populations. American-Indian youth, more than their peers, use SBHCs for behavioral health and checkups. © 2016, American School Health Association.

This study examines patterns of sexual behavior, sexual relating, and sexual risk among HIV-positive men sexually active with women. A total of 278 HIV-positive men were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many were not sexually active at all for months at a time; many continued to have multiple female and at times male partners. Over one-third of the cohort had one or more periods when they had engaged in unprotected sex with a female partner who was HIV-negative or status unknown (unsafe sex). Periods of unsafe sex alternated with periods of safer sex. Contextual factors such as partner relations, housing status, active drug use, and recently exchanging sex showed the strongest association with increased odds of unsafe sex. A number of predictors of unsafe sex among African American men were not significant among the Latino sub-population, suggesting race/ethnic differences in factors contributing to heterosexual transmission. Implications for prevention interventions are discussed.

Snooping and Sexting: Digital Media as a Context for Dating Aggression and Abuse Among College Students.

Digital dating abuse (DDA) is a pattern of behaviors that control, pressure, or threaten a dating partner using a cell phone or the Internet. A survey of 365 college students was conducted, finding that digital monitoring behaviors were especially common. There were no gender differences in number of DDA behaviors experienced, but women reported more negative hypothetical reactions to sexual messaging than men. DDA was associated with measures of physical, sexual, and psychological dating violence. Results suggest that digital media are a context for potentially harmful dating behaviors, and the experience of DDA may differ by gender for sexual behaviors. © The Author(s) 2016.

Neuroanatomical dichotomy of sexual behaviors in rodents: a special emphasis on brain serotonin.

PubMed

Angoa-Pérez, Mariana; Kuhn, Donald M

2015-09-01

Much of the social behavior in which rodents engage is related to reproduction, such as maintaining a breeding territory, seeking mates, mating, and caring for their young. Rodents belong to the internally fertilizing species that require sexual behavior for reproduction. The dyadic, heterosexual patterns of most mammalian species are sexually dimorphic, but they also share mutual components in both sexes: sexual attraction is reciprocal, sexual initiative is assumed, appetitive behavior is engaged in, and mating involves consummatory and postconsummatory phases in females as well as in males. Serotonin, a phylogenetically ancient molecule, is the most widely distributed neurotransmitter in the brain and its signaling pathways are essential for numerous functions including sexual behavior. Since the late 1960s, brain serotonergic neurotransmission has been considered to exert an inhibitory influence on the neural mechanisms mediating sexual behavior. This contention was based mainly on the observations that a decrease in central serotonergic activity facilitated the elicitation of sexual behavior, whereas an increase in central serotonergic activity attenuated it. However, the discovery of over 14 types of serotonin receptors has added numerous layers of complexity to the study of serotonin and sexual behavior. Evidence shows that, upon activation, certain receptor subtypes facilitate, whereas some others suppress, sexual behavior, as well as sexual arousal and motivation. Furthermore, the role of these receptors has been shown to be different in the male and female sexes. The use of serotonergic pharmacological interventions, mouse strains with genetic polymorphisms causing alterations in the levels of brain serotonin, and animal models with genetic manipulations of various serotonin effectors has helped delineate the fundamental role of this neurotransmitter in the regulation of sexual behavior. This review aims to examine the basics of the components of female and male sexual behavior and the participation of the serotonin system in the modulation of these behaviors, with emphasis on rodents.

Childhood sexual trauma has been demonstrated to increase survivors' risk for engaging in unrestricted sexual behaviors and experiencing adolescent sexual assault. The current study used the sexual self-schema construct to examine cognitive representations of sexuality that might drive these behavioral patterns. In Study 1 (N = 774), we attempted to improve the content validity of the Sexual Self Schema Scale for child sexual abuse (CSA) survivors, introducing a fourth sexual self-schema factor titled the "immoral/irresponsible" factor. In Study 2 (N = 1150), the potential differences in sexual self-views, as assessed by the four sexual self-schema factors, between CSA survivors and non-victims were explored. In addition, Study 2 evaluated how these sexual self-schema differences may contribute to participation in unrestricted sexual behaviors and risk for sexual assault in adolescence. Results indicated that a history of CSA impacted the way women viewed themselves as a sexual person on each of the four factors. CSA survivors were found to view themselves as more open and possessing more immoral/irresponsible cognitions about sexuality as compared to women who did not have a CSA history. In addition, the CSA survivors endorsed less embarrassment and passionate/romantic views of their sexual selves. The interaction of CSA severity and the sexual self-schemas explained variance in adolescent sexual assault experiences above and beyond the severity of CSA history and participation in risky sexual behaviors. The findings suggest that sexual self-views may serve to moderate the relationship between CSA and adolescent sexual assault. Implications of these findings and directions for future research are discussed.

The erosion of sexual dimorphism: challenges to religion and religious ethics.

Late modernity has been witnessing the erosion of the dimorphic sexual paradigm that, in both strong and weak forms, has characterized human history as we know it. Recent discoveries in biology and the social sciences have combined with altered patterns in human sexual behavior to raise critical new questions about the inherited paradigm. Religions of the West whose sacred texts, mythologies, and codes of behavior assume that maleness and femaleness are exclusive and complementary types of sexuality-each of which determines sexual identity, reproductive role, social role, and the sex of one's partner-increasingly must grapple with both theoretical evidence for and experiential evidence of polymorphous human sexuality. Inherited categories of dimorphic sexuality not only are challenged but become less and less intelligible.

Late positive potential to explicit sexual images associated with the number of sexual intercourse partners

2015-01-01

Risky sexual behaviors typically occur when a person is sexually motivated by potent, sexual reward cues. Yet, individual differences in sensitivity to sexual cues have not been examined with respect to sexual risk behaviors. A greater responsiveness to sexual cues might provide greater motivation for a person to act sexually; a lower responsiveness to sexual cues might lead a person to seek more intense, novel, possibly risky, sexual acts. In this study, event-related potentials were recorded in 64 men and women while they viewed a series of emotional, including explicit sexual, photographs. The motivational salience of the sexual cues was varied by including more and less explicit sexual images. Indeed, the more explicit sexual stimuli resulted in enhanced late positive potentials (LPP) relative to the less explicit sexual images. Participants with fewer sexual intercourse partners in the last year had reduced LPP amplitude to the less explicit sexual images than the more explicit sexual images, whereas participants with more partners responded similarly to the more and less explicit sexual images. This pattern of results is consistent with a greater responsivity model. Those who engage in more sexual behaviors consistent with risk are also more responsive to less explicit sexual cues.

To determine the sexual behavioral pattern, consequences, and adopted solutions among senior secondary schools students in Ojo military barracks, Lagos. This was a cross-sectional study of 400 senior secondary schools students in Ojo military barracks, Lagos, selected using a multistage sampling technique. Data was collected using pre-tested, self-administered semi-structured questionnaires. Data was analysed using statistical package for social sciences version 17. Tests of statistical significance were carried out using χ2-test, and a p-value of <0.05 was considered significant. The majority of them 391 (97.8%), were in the age group (10-19 years) while the mean age was 15±2.4 for males and 15±2.2 for females, respectively. One hundred and fifty four (38.5%) of the respondents have had penetrative sexual intercourse and were influenced mainly by peer pressure (p=0.0000). Their age at first sexual intercourse ranged between 10-19 years. Ten (6.5%) of the respondents (all males) had their sexual debut with a commercial sex worker. More girls 41 (56.2%) than boys 12 (14.8%), were forced into sexual intercourse (p=0.0000). Over half of the sexually active respondents had at least two sexual partners for either sex. Findings from this study have shown that young people living in the barracks indulged in sexual activity at very early ages and engaged in risky sexual behavior. We therefore recommend an improved multi-sectoral approach in reproductive health and sexually transmitted infections including HIV/AIDS education.

Sexual behavior is a key factor for susceptibility to sexually transmitted diseases. An evaluation of the sexual behavior of women at reproductive age was conducted in 1999. A replication of this study aims to evaluate the current situation and identify changes in sexual behavior, 13 years later. This is a population-based cross-sectional study, conducted with 1071 women in Pelotas, Brazil. Compared to the 1999 study, a 14% increase in early sexual debut and an 8% decrease in the non-use of condoms were observed in 2012. The proportion of women who reported anal sex doubled between these periods. There was no trend of increase or decrease in the prevalence of behaviors with distinct patterns being observed for each of them. Reduction of non-use of condoms may be an indicator of the effectiveness of campaigns to promote safe sex. However, the increased prevalence of early sexual debut and anal sex indicates the need for campaigns to continue and to expand their focus, especially among vulnerable groups.

To examine the relationship between specific youth assets and adolescents' engagement in risky sexual behaviors, as measured by an Aggregate Sexual Risk score, and to specifically explore which youth assets and demographic variables were predictive of youth engagement in risky sexual intercourse. A total of 2108 sexually active high school students attending public high schools in a southern state completed a self-report questionnaire that measured youth assets. Based upon responses to items measuring risk behaviors, an Aggregate Sexual Risk score was calculated for each student. Unconditional logistic regression and multivariate logistic regression analyses were conducted to examine the relationships between the assets and the Aggregate Risk Score. Four separate analyses (white females, white males, black females, and black males) were conducted. In general, the patterns in all four groups indicated that students who had an Aggregate Risk Score of > or = 3 (high risk) possessed less of the measured youth assets. The assets that were most significantly associated with engagement in risky sexual behaviors included self peer values regarding risky behaviors, quantity of other adult support, and youths' empathetic relationships. Thus, students who reported not having these assets were significantly more likely to engage in the risky sexual behaviors. Results underscore the relationship of specific youth assets to sexual risk behaviors. Health researcher and practitioners who work to prevent teen pregnancy and sexually transmitted infections among teenagers need to understand and acknowledge these factors within this population so that the assets can be built or strengthened.

Health-protective effects of attachment among African American girls in psychiatric care.

African American girls in psychiatric care are at increased risk for HIV and sexually transmitted infection (STI) through sexual risk taking. Adolescent sexual behavior often reflects peer norms and behavior. Secure attachment patterns with mothers and peers might lessen the effects of negative peer influences and reduce sexual risk taking among African American girls. This study examined the relationships among mother-daughter and peer attachment, peer norms, and sexual-risk behaviors in African American girls seeking outpatient psychiatric care. A group of 12-16-year-old African American girls (N = 262; M age = 14.45 years) reported on their attachment to their mothers and peers, peer risk-taking and dating behaviors, peer pressure, and sexual-risk behaviors (e.g., number of partners, high-risk partners, and condom use). Structural equation modeling examined whether peer attachment and peer norms mediated the relationship between mother attachment and sexual risk. Findings supported peer norms, but not peer attachment, as a mediator of mother attachment and girls' sexual-risk behaviors. Findings revealed important family and peer factors for African American girls in psychiatric care. HIV prevention programs may be strengthened by improving mother-daughter relationships, addressing the importance of peer relationships, and emphasizing how secure mother-daughter relationships can temper the impact of peer norms.

Controversy exists concerning mechanisms by which progesterone exerts central nervous system effects on behavior. Progesterone may affect behavior by genomic regulation of protein synthesis. Alternatively, it may work through non-genomic mechanisms, consistent with its short latency to act. Recent work suggests that progesterone may elicit its effects on sexual behavior by more than one mechanism in a tissue specific manner. In the present study, we have examined whether progesterone facilitation of sexual behavior is correlated with modification of protein synthesis patterns in the ventromedial hypothalamus (VMH). Ovariectomized rats were divided into three groups: estradiol (4 ug/ka at 0 and 18more » hrs), estradiol (at 0 and 18 hrs) plus progesterone (2 mg/kg at 37 hrs), and vehicle only. {sup 35}S-labeled cysteine and methionine were bilaterally infused into the VMH at 37 hrs (the time of progesterone administration). Following 4 hrs of infusion, animals were tested for sexual behavior and sacrificed. Newly synthesized VMH proteins were separated by two dimensional gel electrophoresis followed by fluorography. Analysis of approximately 660 spots/fluorogram in two independent replications indicated that no protein was completely induced or lost as a result of being treated with progesterone. The abundances of several proteins were significantly altered in response to progesterone treatment in each replication; however, none were changed in abundance in both replications. These findings present no evidence that progesterone causes detectable alterations in VIMH protein patterns between 10-100 kDa in the 4.8-6.7 apparent pI range.« less

The present study was designed to test a model of contextual and intrapersonal predictors of adolescent risky sexual behaviors and of sexually transmitted infection diagnoses. Using Waves I and II from the National Longitudinal Study of Adolescent Health, the authors estimated a structural model in which intrapersonal factors such as adolescents' attitudes about sex, perceived parental norms, knowledge about sexual health, and birth-control self-efficacy partially mediated the effects of contextual factors such as parent-adolescent relationship quality, school connectedness, and exposure to AIDS and pregnancy education on a number of risky sexual behaviors and outcomes: early sex initiation, sex under the influence of substances, condom use at last intercourse, and having been diagnosed with a sexually transmitted infection. Different patterns of direct and mediated effects emerged for each sexual outcome. Results are discussed in terms of the complex interplay between environment and individual and in terms of how, when, and with whom to intervene in order to improve adolescent sexual health outcomes.

Objectives. We examined (1) whether sexual minority youths (SMYs) are at increased risk for physical dating violence victimization (PDVV) compared with non-SMYs, (2) whether bisexual youths have greater risk of PDVV than lesbian or gay youths, (3) whether youths who have had sexual contact with both sexes are more susceptible to PDVV than youths with same sex–only sexual contact, and (4) patterns of PDVV among SMYs across demographic groups. Methods. Using 2 measures of sexual orientation, sexual identity and sexual behavior, and compiling data from 9 urban areas that administered the Youth Risk Behavior Surveys from 2001 to 2011, we conducted logistic regression analyses to calculate odds of PDVV among SMYs across demographic sub-samples. Results. SMYs have significantly increased odds of PDVV compared with non-SMYs. Bisexual youths do not have significantly higher odds of PDVV than gay or lesbian youths, but youths who had sexual contact with both-sexes possess significantly higher odds of PDVV than youths with same sex–only sexual contact. These patterns hold for most gender, grade, and racial/ethnic subgroups. Conclusions. Overall, SMYs have greater odds of PDVV versus non-SMYs. Among SMYs, youths who had sexual contact with both sexes have greater odds of PDVV than youths with same sex–only sexual contact. Prevention programs that consider sexual orientation, support tolerance, and teach coping and conflict resolution skills could reduce PDVV among SMYs. PMID:25121813

Variability in mood swings is a characteristic of borderline personality disorder (BPD) and is associated with suicidal behavior. This study investigated patterns of mood variability and whether such patterns could be predicted from demographic and suicide-related psychological risk factors. Eighty-two adults with BPD and histories of recurrent suicidal behavior were recruited from 3 outpatient psychiatric programs in Canada. Experience sampling methodology (ESM) was used to assess negative mood intensity ratings on a visual analogue scale, 6 random times daily, for 21 days. Three-level models estimated variability between times (52.8%), days (22.2%), and patients (25.1%) and supported a quadratic pattern of daily mood variability. Depression scores predicted variability between patients' initial rating of the day. Average daily mood patterns depended on levels of hopelessness, suicide ideation, and sexual abuse history. Patients reporting moderate to severe sexual abuse and elevated suicide ideation were characterized by worsening moods from early morning up through evening, with little or no relief; patients reporting mild sexual abuse and low suicide ideation reported improved mood throughout the day. These patterns, if replicated in larger ESM studies, may potentially assist the clinician in determining which patients require close monitoring.

This research compared data from two studies of women's sexual behavior--one conducted in the 1940s, the other in the 1980s. The first sample included 3952 white women, ages 18 to 36, drawn from the larger sample of women who participated in the original Kinsey study. The second comprised 122 white women, in the same age range, who had taken part in a recent study of sexual socialization and experiences among women in Los Angeles County, CA. Log-linear analyses were used to control for differences between the samples on age, education, and marital status. Comparisons were conducted in the areas of childhood family characteristics; sexual socialization and education; sexual behavior in childhood, adolescence, and adulthood; contraceptive practices; and child sexual abuse. Results tended to reflect changes that have taken place in society and in patterns of sexual behavior. Differences in sexual socialization pointed to the increased role of the media and the schools and to more relaxed attitudes about nudity in the home. Shifts in sexual behavior were particularly dramatic. As compared to women in the Kinsey sample, the newer subjects began intercourse earlier, were less likely to have a fiance or husband as their first partner, reported a higher number of sexual partners, and participated in a broader range of sexual behaviors. Contraceptive practices differed considerably, especially among never-married women. Women in the new study were also more likely to report instances of child sexual abuse. Methodological and social factors contributing to the findings are discussed.

Measuring Sexual Motives: A Test of the Psychometric Properties of the Sexual Motivations Scale.

Sexual motives refer to functions served by sexual behavior. The Sex Motivations Scale (SMS) has frequently been used to assess sexual motives. At its development, the SMS demonstrated good internal consistency; convergent, divergent, and criterion validity; and configural invariance across sex, age, and Caucasians and African Americans. Yet the metric and scalar invariance of the SMS has not been examined, nor has the measurement invariance of the SMS across Hispanic and Asian Americans, sexual minority status, and relationship status been tested. The criterion validity of the SMS also has yet to be examined for nonintercourse sexual behaviors, such as sexting. The present study aimed to address these gaps in a diverse sample of 2,201 college students (77.60% female; M age  = 22.06; 27.84% Caucasian). Results further affirmed the configural, metric, and scalar invariance of the SMS. The convergent and divergent validity of the SMS was supported in relation to positive and negative affect and attachment patterns; and specific SMS subscales demonstrated associations with sexual intercourse behaviors and sexting, supporting the criterion validity of the SMS. These findings suggest the relevance of the SMS in assessing sexual motives across diverse populations and behaviors.

Viewing Time Measures of Sexual Orientation in Samoan Cisgender Men Who Engage in Sexual Interactions with Fa’afafine

2015-01-01

Androphilia refers to attraction to adult males, whereas gynephilia refers to attraction to adult females. The current study employed self-report and viewing time (response time latency) measures of sexual attraction to determine the sexual orientation of Samoan cisgender men (i.e., males whose gender presentation and identity is concordant with their biological sex) who engage in sexual interactions with transgender male androphiles (known locally as fa’afafine) compared to: (1) Samoan cisgender men who only engage in sexual interactions with women, and (2) fa’afafine. As expected, both measures indicated that cisgender men who only engaged in sexual interactions with women exhibited a gynephilic pattern of sexual attraction, whereas fa’afafine exhibited an androphilic one. In contrast, both measures indicated that cisgender men who engaged in sexual interactions with fa’afafine demonstrated a bisexual pattern of sexual attraction. Most of the cisgender men who exhibited bisexual viewing times did not engage in sexual activity with both men and women indicating that the manner in which bisexual patterns of sexual attraction manifest behaviorally vary from one culture to the next.

2010-01-01

Forty-two patients treated for in situ vulvar cancer at two institutions participated in structured assessment interviews and completed questionnaires to examine postoperative sexual, marital, and psychological adjustment. Patient responses were compared with a matched sample of gynecologically healthy women. The results indicated a specific pattern of sexual disruption for the women treated for preinvasive disease. Sexual behavior patterns appeared to be maintained, as was the desire phase of the sexual response cycle. However, there was specific disruption of the phases of excitement and resolution and, to a lesser extent, orgasm. In addition to a two- to threefold increase in the frequency of sexual dysfunction, 30% of the sample was sexually inactive at follow-up. Although replication of these findings is necessary, this investigation suggests that sexual functioning correlates with the magnitude of treatment. PMID:3336539

Objective: The current study develops an empirically determined classification of sexual orientation developmental patterns based on participants’ annual reports of self-identifications, sexual attractions, and sexual behaviors during the first 4 years of college. A secondary aim of the current work was to examine trajectories of alcohol involvement among identified subgroups. Method: Data were drawn from a subsample of a longitudinal study of incoming first-time college students at a large, public university (n = 2,068). Longitudinal latent class analysis was used to classify sexual minority participants into empirically derived subgroups based on three self-reported facets of sexual orientation. Multivariate repeated-measures analyses were conducted to examine how trajectories of alcohol involvement varied by sexual orientation class membership. Results: Four unique subclasses of sexual orientation developmental patterns were identified for males and females: one consistently exclusively heterosexual group and three sexual minority groups. Despite generally similar alcohol use patterns among subclasses, certain sexual minority subgroups reported elevated levels of alcohol-related negative consequences and maladaptive motivations for use throughout college compared with their exclusively heterosexual counterparts. Conclusions: Elevations in coping and conformity motivations for alcohol use were seen among those subgroups that also evidenced heightened negative alcohol-related consequences. Implications and limitations of the current work are discussed. PMID:22333337

On sexual behavior and sex-role reversal.

PubMed

Schuiling, Gerard A

2005-09-01

Sex is not about reproduction; sex is about (re-)combination of DNA. Sex, not reproduction, always involves physical contact between two individuals; to achieve this, strategies of sexual behavior evolved. Sexual behavior, therefore, did not evolve as part of a reproductive strategy, but evolved to enable exchange of genetic material. In multicellular organisms the situation is more complicated than in unicellular organisms, as it is impossible for each cell within a multicellular body to have sex with another cell. Hence, evolution selected a system in which the possibility to have sex was limited to only one cell-line: the germ cells. As a result, sex adopted the character of fertilization, and sex and reproduction became inseparably linked. Still, in some species, including humans, sexual behavior still exhibits features of its evolutionary past: in humans (like in bonobo's) most sexual activity and many sexual behavioral patterns have nothing to do with reproduction (masturbation, homosexual behavior, for example); in humans, sexual behavior also became associated with other strategic objectives, such as intensifying the pair bond, expression of love or power. Different genders - male and female - evolved, and each gender evolved typical gender-related sexual and reproductive strategies as well. In most multicellular species, these strategies became inextricably mixed, and sexual behavior increasingly more - and in most species even exclusively - 'served' the interests of reproduction: sexual behavior became more or less synonymous with reproductive behavior. In most species, the 'mix' of sexual and reproductive strategies evolved into typical gender-related patterns of behavior, that is, in typical 'sex-roles'. Often, males are bigger and more 'beautiful' (= more intensely ornamented) than females; males compete with each other for access to females; males court females, while females choose males ('female choice'). However, ecological circumstances may cause a reversal of sex-roles, resulting in a situation in which females are bigger and more intensely ornamented than males, females compete for access to males, females court males and only males invest in care for the young, provided they are relatively certain of their paternity. Also, as in the case of the spotted hyena, females may be highly virilized and be socially dominant. This 'sex-role reversal' is seen, e.g., when males are relatively rare due to high predation pressure, or when the process of reproduction is very risky for the same reason: then it is 'better' that males, with their plenty of sperm, are wasted, than females with their few, precious eggs. It can be argued, with women being the fair sex, exhibiting competitive behavior and with an actively displaying courtship, and with men investing heavily in their offspring, meanwhile taking all (cultural) kinds of measures to guarantee their paternity, that humans, too, exhibit some degree of sex-role reversal.

Sexual partner preference in female Japanese macaques.

PubMed

Vasey, Paul L

2002-02-01

Whether animals ever exhibit a preference for same-sex sexual partners is a subject of debate. Japanese macaques represent excellent models for examining issues related to sexual preference in animals because females, in certain populations, routinely engage in both heterosexual and homosexual behavior over the course of their life spans. Multiple lines of evidence indicate that female homosexual behavior in Japanese macaques is a sexual behavior, not a sociosexual one. Additional evidence indicates that female Japanese macaques do not engage in homosexual behavior simply because acceptable male mates are unavailable or unmotivated to copulate. Patterns of sexual partner choice by female Japanese macaques that are the focus of intersexual competition indicate that females of this species choose same-sex sexual partners even when they are simultaneously presented with a motivated, opposite-sex alternative. Thus, in some populations of Japanese macaques, females prefer certain same-sex sexual partners relative to certain male mates, and vice versa. Taken together, this evidence suggests that female Japanese macaques are best characterized as bisexual in orientation, not preferentially homosexual or preferentially heterosexual.

Postpartum months provide a challenging period for poor women. This study examined patterns of menstrual resumption, sexual behaviors and contraceptive use among urban poor postpartum women. Women were eligible for this study if they had a birth after the period September 2006 and were residents of two Nairobi slums of Korogocho and Viwandani. The two communities are under continuous demographic surveillance. A monthly calendar type questionnaire was administered retrospectively to cover the period since birth to the interview date and data on sexual behavior, menstrual resumption, breastfeeding patterns, and contraception were collected. The results show that sexual resumption occurs earlier than menses and postpartum contraceptive use. Out of all postpartum months where women were exposed to the risk of another pregnancy, about 28% were months where no contraceptive method was used. Menstrual resumption acts as a trigger for initiating contraceptive use with a peak of contraceptive initiation occurring shortly after the first month when menses are reported. There was no variation in contraceptive method choice between women who initiate use before and after menstrual resumption. Overall, poor postpartum women in marginalized areas such as slums experience an appreciable risk of unintended pregnancy. Postnatal visits and other subsequent health system contacts provide opportunities for reaching postpartum women with a need for family planning services.

Risky Sex in High-Risk Adolescents: Associations with Alcohol Use, Marijuana Use, and Co-Occurring Use.

2018-04-01

Risky sexual behavior and substance use appear to be interconnected behaviors among adolescents, but data are scarce regarding the extent to which sexual risk behavior is associated with high levels of marijuana and alcohol use, both separately and in combination. 301 adolescents were recruited from a short-term detention facility, and substance use and risky sexual behavior were assessed. We found that adolescents who frequently used marijuana, but not alcohol, reported significantly less risky sex as well as greater intentions to use condoms than either adolescents who frequently used alcohol, but not marijuana, or adolescents who frequently used both substances. Substance use status as a predictor of future risky sexual behavior followed a similar pattern. When designing interventions to reduce substance use in the context of risky sex, it might be especially effective to target efforts toward reducing harm associated with alcohol use, either alone or in combination with marijuana use.

Broad Autism Phenotypic Traits and the Relationship to Sexual Orientation and Sexual Behavior.

Individuals with higher levels of the broad autism phenotype (BAP) have some symptoms of autism spectrum disorder (ASD). Like individuals with ASD, people with higher-BAP may have fewer sexual experiences and may experience more same-sex attraction. This study measured BAP traits, sexual experiences, and sexual orientation in typically developing (TD) individuals to see if patterns of sexual behavior and sexual orientation in higher-BAP resemble those in ASD. Although BAP characteristics did not predict sexual experiences, one BAP measure significantly predicted sexual orientation, β = 0.22, t = 2.72, p = .007, controlling for demographic variables (R 2 change = .04, F = 7.41, p = .007), showing individuals with higher-BAP also reported increased same-sex attraction. This finding supports the hypothesis that individuals with higher-BAP resemble ASD individuals in being more likely than TD individuals to experience same-sex attraction.

HIV-Positive Men Sexually Active with Women: Sexual Behaviors and Sexual Risks

2006-01-01

This study examines patterns of sexual behavior, sexual relating, and sexual risk among HIV-positive men sexually active with women. A total of 278 HIV-positive men were interviewed every 6–12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many were not sexually active at all for months at a time; many continued to have multiple female and at times male partners. Over one-third of the cohort had one or more periods when they had engaged in unprotected sex with a female partner who was HIV-negative or status unknown (unsafe sex). Periods of unsafe sex alternated with periods of safer sex. Contextual factors such as partner relations, housing status, active drug use, and recently exchanging sex showed the strongest association with increased odds of unsafe sex. A number of predictors of unsafe sex among African American men were not significant among the Latino sub-population, suggesting race/ethnic differences in factors contributing to heterosexual transmission. Implications for prevention interventions are discussed. PMID:16770702

Predictors of Intrusive Sexual Behaviors in Preschool-Aged Children.

Intrusive sexual behaviors (ISBs) are a specific type of problematic sexual behavior characterized by the invasive nature of the acts (e.g., touching others' private parts, attempting intercourse; Friedrich, 1997). The limited amount of research on ISBs has focused on sexual abuse history as the primary predictor. However, Friedrich, Davies, Feher, and Wright (2003) found that ISBs in children up to age 12 were related to four broad conceptual factors: (a) exposure to sexual content, (b) exposure to violent behavior, (c) family adversity, and (d) child vulnerabilities. The current study sought to replicate Friedrich's study using a clinical sample of 217 preschool-aged children (ages two to six). Results supported variables from within the child vulnerabilities construct (externalizing behaviors, β EXT  = 0.032, p = 0.001), post-traumatic stress disorder (PTSD) criteria met (β PTSD  = 0.177, p = 0.02), and an inverse relationship with age (β AGE  = -0.206, p = 0.024). These results highlight the importance of considering childhood behavioral patterns and reactivity to traumatic events as correlates of ISBs in young children.

We describe the sexual behaviors of women at elevated risk of HIV acquisition who reside in areas of high HIV prevalence and poverty in the US. Participants in HPTN 064, a prospective HIV incidence study, provided information about individual sexual behaviors and male sexual partners in the past 6 months at baseline, 6- and 12-months. Independent predictors of consistent or increased temporal patterns for three high-risk sexual behaviors were assessed separately: exchange sex, unprotected anal intercourse (UAI) and concurrent partnerships. The baseline prevalence of each behavior was >30 % among the 2,099 participants, 88 % reported partner(s) with >1 HIV risk characteristic and both individual and partner risk characteristics decreased over time. Less than high school education and food insecurity predicted consistent/increased engagement in exchange sex and UAI, and partner's concurrency predicted participant concurrency. Our results demonstrate how interpersonal and social factors may influence sustained high-risk behavior by individuals and suggest that further study of the economic issues related to HIV risk could inform future prevention interventions.

Geosocial networking applications (e.g., "hookup apps") are widely used among adult men who have sex with men (MSM). Little is known about adolescent MSM's (AMSM) use of these apps. Exploratory research is needed as AMSM's app use poses various ethical, legal, and sexual health concerns. This article examined AMSM's app use patterns and its associations with their sexual health and behavior. Two hundred sexually experienced AMSM in the United States (M age = 16.6, 49% racial/ethnic minority) completed online survey questions assessing their use of apps specific to MSM and not specific to MSM to meet partners for dating and sex, as well as their sexual behavior and HIV risk. Overall, 52.5% of participants (n = 105) reported using MSM-specific apps to meet partners for sex. Of these, most participants reported having oral (75.7%, n = 78) and anal sex (62.1%, n = 64) with those partners. Of those who reported having anal sex, 78.1% (n = 50) had sex with those partners more than once, and only 25.0% (n = 16) always used condoms with those partners. Relative to those who used only non-MSM-specific apps, MSM-specific app users reported more sex partners and condomless anal sex partners, greater perceived risk of HIV, more engagement in sexual health services, and greater odds of HIV testing. Use of MSM-specific apps was not uncommon among this sample of AMSM. Patterns of risk behavior and HIV testing were similar to samples of adult MSM app users. Further research should investigate AMSM's app-related sexual and HIV/sexually transmitted infection prevention decision-making to guide sexual health education efforts for AMSM.

This study evaluated relations between sexual sensation seeking, co-occurring sex and alcohol use, and sexual risk behaviors (eg, unprotected intercourse and multiple sex partners) among adolescents receiving treatment for substance abuse problems. The ethnically diverse sample included 394 adolescents recruited from outpatient treatment (280 males; Mage  = 16.33 years, SDage  = 1.15). Structural equation modeling (SEM) was used to test direct and indirect paths between sexual sensation seeking and sexual risk behaviors via the frequency of co-occurring sex and alcohol use. Conditional indirect effects by gender were also tested. Analyses identified significant effects of sexual sensation seeking on co-occurring sex and alcohol use and sexual risk behaviors. The path from co-occurring sex and alcohol use to unprotected intercourse was significantly stronger among adolescent girls, suggesting a mediation effect moderated by gender. No gender difference was found for the indirect path from sexual sensation seeking and number of past year sexual partners via co-occurring sex and alcohol use. Selected prevention efforts are needed to promote HIV risk reduction among adolescents in substance abuse treatment. The documented conditional indirect effect for unprotected intercourse suggests that HIV prevention programs should pay special attention to gender-specific patterns of alcohol use and sexual risk behavior when tailoring program content.

1979-01-01

Sexual behavior patterns among Nigerian university students and factors influencing them were studied. While permarital cohabitation is common, a large percentage (48%) had their first coital experience between the ages of 22 and 27. Religion does not appear to have a strong inhibiting influence on premarital sex, although it does affect the frequency of changing partners. Contraceptives, although known to almost all the respondents, are not widely used. The use of contraceptives had little influence on premarital cohabitation. Oral-genital, male-male, and female-female sexual practices are very uncommon.

Maternal Patterns of Marijuana Use and Early Sexual Behavior in Offspring of Teenage Mothers

Teenage mothers use marijuana more frequently than older mothers, and marijuana use may predict HIV risk behavior in offspring. Our goals were to (1) describe trajectories of marijuana use in teenage mothers and (2) determine if these trajectories were associated with early sexual behavior in their offspring. Pregnant adolescents (12–18 years) were recruited at a prenatal clinic and interviewed during pregnancy, at delivery, and during follow-up visits when offspring were 6, 10, 14 and 16 years old. At 16 years, 332 women (71 % Black, 29 % White) and their offspring were assessed. Mothers were asked about their marijuana use at each time point. Offspring reported on their sexual behavior at age 14. Trajectory analyses using growth mixture models revealed four maternal patterns of marijuana use: no use, only at the 6 year follow-up, quit by the 16 year follow-up, and used across most of the time points. The children of chronic users were more likely to have early sex. The maternal marijuana trajectory group variable remained a statistically significant predictor in multivariate models controlling for race, gender, socioeconomic status, child pubertal timing, child externalizing behavior problems, and child marijuana use. These findings suggest that a minority of teenage mothers continue to use marijuana over time. Chronic maternal marijuana use across a decade was associated with early sex in offspring (oral or vaginal sex by age 14). Early sexual behavior places these children at significantly higher risk of teenage pregnancy and HIV risk behaviors. PMID:24942139

HIV/AIDS continues to be a health disparity faced by sexual minority men, and is exacerbated by non-injection drug use. We sought to delineate growth in non-injection drug use and condomless sex in a sample of racially and economically diverse of gay, bisexual, and other young men who have sex with men (YMSM) as they emerged into adulthood between the ages of 18 and 21 and who came of age in the post-HAART era. Behavioral data on drug use and condomless sex, collected via a calendar based technique over 7 waves of a cohort study of 600 YMSM, were analyzed using latent growth curve modeling to document patterns of growth in these behaviors, their associations, and the extent to which patterns and associations are moderated by race/ethnicity and socioeconomic status. Significant growth was noted in the frequencies of condomless oral and anal intercourse, alcohol to intoxication, marijuana use, and inhalant nitrate use. High levels of association were noted between all behaviors across time but associations did not differ by either race/ethnicity or socioeconomic status. The link between drug use and risky sexual behavior continue to be evident in YMSM with significant increases in these behaviors demonstrated as YMSM transition between adolescence and young adulthood. Conclusions/Importance: Healthcare for a new generation of sexual minority males must address the synergy of these behaviors and also nest HIV prevention and care within a larger context of sexual minority health that acknowledges the advances made in the last three decades.

Effects of Intranasal Oxytocin Administration on Sexual Functions in Healthy Women: A Laboratory Paradigm.

The neuropeptide oxytocin (OXT) has a variety of physiological functions in maternal behavior and attachment including sexual behavior. Based on animal research and our previous human studies, we set out to investigate intranasal administration of OXT and hypothesized that OXT should be able to modulate sexual function in women. In a double-blind, placebo-controlled, crossover laboratory setting, the acute effects of intranasal administered OXT (24 international units) on sexual drive, arousal, orgasm, and refractory aspects of sexual behavior were analyzed in 27 healthy females (mean age ± SD, 27.52 ± 8.04) together with physiological parameters using vaginal photoplethysmography. Oxytocin administration showed no effect on subjective sexual parameters (eg, postorgasmic tension; P = 0.051). Physiological parameters (vaginal photoplethysmography amplitude and vaginal blood volume) showed a response pattern towards sexual arousal but were not affected by OXT. Using a well-established laboratory paradigm, we did not find that intranasal OXT influences female sexual parameters. Also, sexual drive and other functions were not affected by OXT. These findings indicate that OXT is not able to significantly increase subjective and objective parameters of sexual function in a setting with high internal validity; however, this might be different in a more naturalistic setting.

Perinatal administration of aromatase inhibitors in rodents as animal models of human male homosexuality: similarities and differences.

PubMed

Olvera-Hernández, Sandra; Fernández-Guasti, Alonso

2015-01-01

In this chapter we briefly review the evidence supporting the existence of biological influences on sexual orientation. We focus on basic research studies that have affected the estrogen synthesis during the critical periods of brain sexual differentiation in male rat offspring with the use of aromatase inhibitors, such as 1,4,6-androstatriene-3,17 (ATD) and letrozole. The results after prenatal and/or postnatal treatment with ATD reveal that these animals, when adults, show female sexual responses, such as lordosis or proceptive behaviors, but retain their ability to display male sexual activity with a receptive female. Interestingly, the preference and sexual behavior of these rats vary depending upon the circadian rhythm.Recently, we have established that the treatment with low doses of letrozole during the second half of pregnancy produces male rat offspring, that when adults spend more time in the company of a sexually active male than with a receptive female in a preference test. In addition, they display female sexual behavior when forced to interact with a sexually experienced male and some typical male sexual behavior when faced with a sexually receptive female. Interestingly, these males displayed both sexual behavior patterns spontaneously, i.e., in absence of exogenous steroid hormone treatment. Most of these features correspond with those found in human male homosexuals; however, the "bisexual" behavior shown by the letrozole-treated rats may be related to a particular human population. All these data, taken together, permit to propose letrozole prenatal treatment as a suitable animal model to study human male homosexuality and reinforce the hypothesis that human sexual orientation is underlied by changes in the endocrine milieu during early development.

Endocrine systems play critical roles in facilitating sexual behavior in seasonally breeding vertebrates. Much of the research exploring this topic has focused on the endocrine correlates of signaling behavior in males and sexual proceptivity in females. What is less understood is how hormones promote the expression of the often complex and highly selective set of stimulus-response behaviors that are observed in naturally breeding animals. In female frogs, phonotaxis is a robust and sensitive bioassay of mate choice and is exhibited by gravid females during the breeding season. In stark contrast, females exhibit low phonotactic responsiveness outside the breeding season, but the administration of hormones can induce sexual proceptivity. Here we test the hypothesis that manipulation of a minimal set of reproductive hormones-progesterone and prostaglandin F2α-are capable of evoking not only proceptive behavior in non-breeding females, but also the patterns of intraspecific selectivity for male sexual displays observed in gravid females tested during the breeding season. Specifically, we investigated whether preferences for faster call rates, longer call durations, and higher call efforts were similar between breeding and hormone-treated females of Cope's gray treefrog (Hyla chrysoscelis). Hormone injections induced patterns of selective phonotaxis in non-breeding females that were remarkably similar to those observed in breeding females. These results suggest that there may be an important contribution of hormonal pleiotropy in regulating this complex, acoustically-guided sexual behavior. Our findings also support the idea that hormonal induction could be used to evaluate hypotheses about selective mate choice, and its underlying mechanisms, using non-breeding females.

Female methamphetamine users: social characteristics and sexual risk behavior.

PubMed

Semple, Shirley J; Grant, Igor; Patterson, Thomas L

2004-01-01

The primary objective of this research was to expand our knowledge regarding the personal and social characteristics of female methamphetamine (meth) users, their motivations for using meth, patterns of meth use, medical and social problems associated with meth use, and the relationship between meth use and sexual risk behaviors. The sample consisted of 98 HIV-negative, heterosexually-identified, meth-using females residing in San Diego, California. Female meth users were characterized by personal and social disadvantage, high rates of psychiatric symptomatology, and high levels of sexual risk behavior, including multiple partners, risky partner types (e.g., anonymous sex partners), and high rates of unprotected vaginal and oral sex. Meth use was also associated with the subjective positive experience of sex. These finding suggest that behavioral interventions should be tailored to the social characteristics of female meth users, and program content should reflect the intertwining of women's sexual experience and meth use.

Does the Organized Sexual Murderer Better Delay and Avoid Detection?

PubMed

Beauregard, Eric; Martineau, Melissa

2016-01-01

According to the organized-disorganized model, organized sexual murderers adopt specific behaviors during the commission of their crimes that contribute to avoiding police detection. The current study examines the effect of sexual murderers' organized behaviors on their ability to both delay and/or avoid police detection. Using a combination of negative binomial and logistic regression analyses on a sample of 350 sexual murder cases, findings showed that although both measures of delaying and avoiding detection are positively correlated, different behavioral patterns were observed. For instance, offenders who moved the victim's body were more likely to avoid detection but the victim's body was likely to be recovered faster. Moreover, victim characteristics have an impact on both measures; however, this effect disappears for the measure of delaying detection once the organized behaviors are introduced. Implications of the findings are discussed. © The Author(s) 2014.

Symbolic meanings of sex in relationships: Developing the Meanings of Sexual Behavior Inventory.

PubMed

Shaw, Amanda M; Rogge, Ronald D

2017-10-01

Consistent with symbolic interactionism and motivation research, the study explored the meanings of sexual behavior in romantic relationships in a sample of 3,003 online respondents. Starting with a pool of 104 respondent-generated items, Exploratory and Confirmatory Factor analyses in separate sample halves revealed a stable set of 9 dimensions within that item pool that formed 2 higher-order factors representing positive (to share pleasure, to bond, to de-stress, to energize the relationship, to learn more about each other) and negative (to manage conflict, as an incentive, to express anger, and to control partner) meanings of sexual behavior within relationships. Item Response Theory analyses helped select the 4-5 most effective items of each dimension for inclusion in the Meanings of Sexual Behavior Inventory (MoSBI). Generalizability analyses suggested that the MoSBI subscale scores continued to show high levels of internal consistency across a broad range of demographic subgroups (e.g., racial/ethnic groups, gay and lesbian respondents, and various levels of education). The MoSBI subscales demonstrated moderate and distinct patterns of association with a range of conceptual boundary scales (e.g., relationship and sexual satisfaction, emotional support, negative conflict behavior, and frequency of sexual behavior) suggesting that these scales represent novel relationship processes. Consistent with this, analyses in the 862 respondents completing a 2-month follow-up assessment suggested that the meanings of sexual behavior predicted residual change in relationship satisfaction, even after controlling for frequency of sexual behavior within the relationships. Implications are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Post-traumatic stress disorder (PTSD) in Veterans is associated with increased sexual risk behaviors, but the nature of this association is not well understood. Typical PTSD measurement deriving a summary estimate of symptom severity over a period of time precludes inferences about symptom variability, and whether momentary changes in symptom severity predict risk behavior. We assessed the feasibility of measuring daily PTSD symptoms, substance use, and high-risk sexual behavior in Veterans using ecological momentary assessment (EMA). Feasibility indicators were survey completion, PTSD symptom variability, and variability in rates of substance use and sexual risk behavior. Nine male Veterans completed web-based questionnaires by cell phone three times per day for 28 days. Median within-day survey completion rates maintained near 90%, and PTSD symptoms showed high within-person variability, ranging up to 59 points on the 80-point scale. Six Veterans reported alcohol or substance use, and substance users reported use of more than one drug. Eight Veterans reported 1 to 28 high-risk sexual events. Heightened PTSD-related negative affect and externalizing behaviors preceded high-risk sexual events. Greater PTSD symptom instability was associated with having multiple sexual partners in the 28-day period. These results are preliminary, given this small sample size, and multiple comparisons, and should be verified with larger Veteran samples. Results support the feasibility and utility of using of EMA to better understand the relationship between PTSD symptoms and sexual risk behavior in Veterans. Specific antecedent-risk behavior patterns provide promise for focused clinical interventions. Published by Elsevier B.V.

By 2015, one-half of all HIV-positive persons in the U.S. will be 50-plus years of age, and as many as 30 % of older adults living with HIV/AIDS continue to engage in unprotected sexual intercourse. Contemporary positive prevention models often include mental health treatment as a key component of HIV prevention interventions. This secondary data analysis characterized longitudinal patterns of sexual behavior in HIV-positive older adults enrolled in a randomized controlled trial of group mental health interventions and assessed the efficacy of psychosocial treatments that targeted depression to reduce sexual risk behavior. Participants were 295 HIV-positive adults ≥50 years of age experiencing mild to severe depressive symptoms, randomized to one of three study conditions: a 12-session coping improvement group intervention, a 12-session interpersonal support group intervention, or individual therapy upon request. Approximately one-fifth of participants reported one or more occasions of unprotected anal or vaginal intercourse with HIV-negative sexual partners or persons of unknown HIV serostatus over the study period. Changes in sexual behavior did not vary by intervention condition, indicating that standalone treatments that target and reduce depression may be insufficient to reduce sexual risk behavior in depressed HIV-positive older adults.

As reflected in elevated rates of sexually transmitted infections, there is a high prevalence of risky sexual behavior among Ugandan university students. It has been assumed that alcohol contributes to risky sexual behavior. However, perhaps owing to methodological issues, this relationship has found only mixed support in empirical research. The present study analyzes the association between alcohol use and risky sexual behavior at the global, situational, and event level among Uganda university students with sexual experience. A cross-sectional survey was carried out in 2010 among 1954 students at Mbarara University of Science and Technology, Uganda, using a self-administered questionnaire. Alcohol use was measured as consumption over the previous 12 months, during situations related to sexual activity and on the most recent occasion of sexual intercourse. Risky sexual behavior was defined as having two or more sexual partners in the previous 12 months or inconsistent condom use with new partners. Bivariate and multivariate logistic regression was performed to analyze the association between alcohol use and risky sexual behavior separately for males and females. Even after adjusting for confounders, the odds ratio (OR) of having two or more sexual partners in the past year indicated a statistically significant association with alcohol use on all levels (global, situational, and event) for both males and females. The ORs of inconsistent condom use with a new partner were significant for males who often consumed alcohol in relation to sexual activity--even after adjusting for potential confounders (OR, 1.75; confidence interval, 1.01-3.08). The risk of inconsistent condom use with a new partner was twice as high for females who often consumed alcohol in relation to sexual activity, although this association was not statistically significant. The study supports previous research that alcohol consumption is associated with having multiple sexual partners. Inconsistent condom use was associated with the situational use of alcohol in relation to sexual activity and was similar for both genders. Interventions to reduce alcohol-related risky sexual behavior should target both male and female drinkers, particularly subgroups of students, who often consume alcohol in relation to sexual activity.

This study investigated: (1) the prevalence and development of 2 receptive (sexually explicit Internet material [SEIM] use and sexual information seeking) and 2 interactive (cybersex and general social networking site [SNS] use) online behaviors in adolescence; (2) whether development of these behaviors predict adolescents' body and sexual self-perceptions; and (3) whether parental strategies regarding adolescents' Internet use reduce engagement in sex-related online behaviors. Four-wave longitudinal data among 1132 seventh- to 10th-grade Dutch adolescents (mean age at wave 1: 13.95 years; 52.7% boys) were collected. Developmental trajectories of sex-related online behaviors were estimated by using latent growth curve modeling. Self-perception outcomes at wave 4 and parental strategies predicting online behaviors were investigated by adding regression paths to growth models. Boys occasionally and increasingly used SEIM. Patterns for girls' SEIM use and boys' and girls' sexual information seeking and cybersex were consistently low. SNS use, however, was a common, daily activity for both. Higher initial levels and/or faster increases in sex-related online behaviors generally predicted less physical self-esteem (girls' SNS use only), more body surveillance, and less satisfaction with sexual experience. Private Internet access and less parental rule setting regarding Internet use predicted greater engagement in sex-related online behaviors. Although most sex-related online behaviors are not widespread among youth, adolescents who engage in such behaviors are at increased risk for developing negative body and sexual self-perceptions. Particular attention should be paid to adolescents' SNS use because this behavior is most popular and may, through its interactive characteristics, elicit more critical self-evaluations. Prevention efforts should focus on parents' role in reducing risky sex-related online behaviors. Copyright © 2014 by the American Academy of Pediatrics.

Affect and Sexual Responsivity in Men with and without a History of Sexual Aggression

Despite increased attention to understanding risk factors for sexual aggression, knowledge regarding the emotional and sexual arousal patterns of sexually aggressive men remains limited. The current study examined whether sexually aggressive men exhibit unique profiles of affective responsivity, in particular to negatively-valenced stimuli, as well as sexual arousal patterns that differentiate them from nonaggressive men. We presented 78 young men (38 sexually aggressive and 40 nonaggressive) with a series of videos designed to induce positive, sad, or anxious affect. Affect and subjective sexual arousal were assessed following each film and erectile responses were measured continuously. Sexually aggressive men reported significantly higher levels of sexual arousal following both the positive and negative conditions as compared to nonaggressive men. Erectile responses of sexually aggressive men were significantly greater than nonaggressive men’s following the positive affect induction. Self-reported positive affect, but not negative affect, was a significant predictor of subjective sexual arousal for both groups of men. Compared to nonaggressive men, sexually aggressive men showed significantly weaker correlations between subjective and physiological sexual arousal. Findings suggest that generalized heightened propensity for sexual arousal may be a risk factor for sexually aggressive behavior. PMID:28388245

Rethinking sexual initiation: pathways to identity formation among gay and bisexual Mexican male youth.

Carrillo, Héctor; Fontdevila, Jorge

2011-12-01

The topic of same-sex sexual initiation has generally remained understudied in the literature on sexual identity formation among sexual minority youth. This article analyzes the narratives of same-sex sexual initiation provided by 76 gay and bisexual Mexican immigrant men who participated in interviews for the Trayectos Study, an ethnographic study of sexuality and HIV risk. These participants were raised in a variety of locations throughout Mexico, where they also realized their same-sex attraction and initiated their sexual lives with men. We argue that Mexican male same-sex sexuality is characterized by three distinct patterns of sexual initiation--one heavily-based on gender roles, one based on homosociality, and one based on object choice--which inform the men's interpretations regarding sexual roles, partner preferences, and sexual behaviors. We analyzed the social factors and forms of cultural/sexual socialization that lead sexual minority youth specifically to each of these three patterns of sexual initiation. Our findings confirm the importance of studying same-sex sexual initiation as a topic in its own right, particularly as a tool to gain a greater understanding of the diversity of same-sex sexual experiences and sexual identities within and among ethnic/cultural groups.

Since self-reports of sensitive behaviors play an important role in HIV/AIDS research, the accuracy of these measures has often been examined. In this paper we (1) examine the effect of three survey interview methods on self-reported sexual behavior and perceptions of community sexual norms in Botswana, and (2) introduce an interview method to research on self-reported sexual behavior in sub-Saharan Africa. Comparing across these three survey methods (face-to-face, ballot box, and randomized response), we find that ballot box and randomized response surveys both provide higher reports of sensitive behaviors; the results for randomized response are particularly strong. Within these overall patterns, however, there is variation by question type; additionally the effect of interview method differs by sex. We also examine interviewer effects to gain insight into the effectiveness of these interview methods, and our results suggest that caution be used when interpreting the differences between survey methods.

Differential patterns of amygdala and ventral striatum activation predict gender-specific changes in sexual risk behavior.

Although the initiation of sexual behavior is common among adolescents and young adults, some individuals express this behavior in a manner that significantly increases their risk for negative outcomes including sexually transmitted infections. Based on accumulating evidence, we have hypothesized that increased sexual risk behavior reflects, in part, an imbalance between neural circuits mediating approach and avoidance in particular as manifest by relatively increased ventral striatum (VS) activity and relatively decreased amygdala activity. Here, we test our hypothesis using data from seventy 18- to 22-year-old university students participating in the Duke Neurogenetics Study. We found a significant three-way interaction between amygdala activation, VS activation, and gender predicting changes in the number of sexual partners over time. Although relatively increased VS activation predicted greater increases in sexual partners for both men and women, the effect in men was contingent on the presence of relatively decreased amygdala activation and the effect in women was contingent on the presence of relatively increased amygdala activation. These findings suggest unique gender differences in how complex interactions between neural circuit function contributing to approach and avoidance may be expressed as sexual risk behavior in young adults. As such, our findings have the potential to inform the development of novel, gender-specific strategies that may be more effective at curtailing sexual risk behavior.

Paced mating behavior is affected by clitoral-vaginocervical lidocaine application in combination with sexual experience.

The present study tested the effects of lidocaine anesthetic ointment applied to the vaginocervical (Experiment 1) or clitoral-vaginocervical (Experiment 2) areas on the display of paced mating behavior over the course of five weekly tests in ovariectomized, hormone-primed, Long-Evans rats. Experiment 3 tested whether rats that acquired sexual experience without ointment application would exhibit altered paced mating behavior on a fifth test under clitoral-vaginocervical lidocaine or vehicle application. Although rats in Experiment 1 and Experiment 2 exhibited shorter contact-return latencies after intromission and reduced likelihood of leaving the male compartment following mounts and intromissions after gaining sexual experience, only rats that received clitoral-vaginocervical lidocaine exhibited altered paced mating behavior relative to vehicle. Specifically, clitoral-vaginocervical lidocaine resulted in shorter contact-return latency to ejaculation and greater percentage of time with the male. Paced mating behavior of sexually experienced rats in Experiment 3 was not disrupted when tested after clitoral-vaginocervical lidocaine treatment. Together, these studies suggest that the sensory input during repeated mating encounters affects the pattern of paced mating behavior that develops with sexual experience.

Domain-Specific Relationships in Sexual Measures of Impulsive Behavior.

PubMed

Mahoney, Colin T; Lawyer, Steven R

2018-04-25

Impulsivity is an important construct for understanding sexual behaviors, but behavioral and self-report measures of impulsivity often are not correlated. One possible explanation for this is that there is little shared variance in the measures because behavioral measures index impulsivity by asking questions about monetary preferences, while self-report measures index impulsivity by asking about a broad range of real-world outcomes (including those of a sexual nature) largely unrelated to money-related preferences. Undergraduate students (total N = 105; female n = 77, male n = 28) completed laboratory measures-delay discounting (DD) and probability discounting (PD)-for two different outcomes-money and sexual activity. Participants also completed the Delaying Gratification Inventory (DGI), which measures difficulty with delaying gratification (i.e., impulsivity) across different domains, including money and physical pleasures. Findings indicated that DD and PD for money were not related to any of the DGI subscales. However, DD for sexual activity was significantly related to the DGI Physical Pleasures subscale, but not other subscales. These findings suggest that the relationship between behavioral and self-report measures of impulsive choice may be stronger when both are measuring domain-specific rather than domain-general behavioral patterns, but further research is warranted.

Male rats that differ in novelty exploration demonstrate distinct patterns of sexual behavior

High versus low novelty exploration predicts a variety of behavioral differences. For example, rats selectively-bred for high novelty exploration (bred High Responders, bHR) exhibit exaggerated aggression, impulsivity, and proclivity to addictive behaviors compared to low novelty-reactive rats (bred Low Responders, bLRs), which are characterized by a high anxiety/depressive-like phenotype. Since bHR/bLR rats exhibit differences in dopaminergic circuitry and differential response to rewarding stimuli (i.e., psychostimulants, food), the present study examined whether they also differ in another key hedonic behavior – sex. Thus, adult bHR/bLR males were given five 30-min opportunities to engage in sexual activity with a receptive female. Sexual behavior and motivation were examined and compared between the groups. The bHR/bLR phenotype affected both sexual motivation and behavior, with bLR males demonstrating reduced motivation for sex compared with bHR males (i.e., fewer animals copulated, longer latency to engage in sex). The bHR males required more intromissions at a faster pace per ejaculation than did bLR males. Thus, neurobiological differences that affect motivation for drugs of abuse, aggression, and impulsivity in rats also affect sexual motivation and performance. PMID:23398441

We assessed whether a meaningful set of latent risk profiles could be identified in an inner-city population through individual and network characteristics of substance use, sexual behaviors, and mental health status. Data came from 600 participants in Social Network Study III, conducted in 2009 in Winnipeg, Manitoba, Canada. We used latent class analysis (LCA) to identify risk profiles and, with covariates, to identify predictors of class. A 4-class model of risk profiles fit the data best: (1) solitary users reported polydrug use at the individual level, but low probabilities of substance use or concurrent sexual partners with network members; (2) social-all-substance users reported polydrug use at the individual and network levels; (3) social-noninjection drug users reported less likelihood of injection drug and solvent use; (4) low-risk users reported low probabilities across substances. Unstable housing, preadolescent substance use, age, and hepatitis C status predicted risk profiles. Incorporation of social network variables into LCA can distinguish important subgroups with varying patterns of risk behaviors that can lead to sexually transmitted and bloodborne infections.

Differences in gay men's AIDS risk knowledge and behavior patterns in high and low AIDS prevalence cities.

Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters.

Objectives. We sought to examine the relationships among childhood sexual abuse, social discrimination, psychological distress, and HIV-risk among Latino gay and bisexual men in the United States. Methods. Data were from a probability sample of 912 men from Miami, FL; Los Angeles, CA; and New York, NY. We used logistic regression and path analyses to examine direct and indirect effects of childhood sexual abuse on psychological distress and sexual risk behavior. Results. We found a 15.8% (95% confidence interval = 12.3%, 19.2%) prevalence of childhood sexual abuse. Not having sex before age 16 years and having consensual sex before age 16 years did not differ from each other in predicting any of the outcomes of interest. Forced sex was associated with a significantly increased risk for all outcomes. A path analyses yielded direct effects of childhood sexual abuse and exposure to homophobia during childhood and during adulthood on psychological distress and indirect effects on risky sexual behavior. Conclusions. HIV-risk patterns among Latino gay and bisexual men are related to childhood sexual abuse and a social context of discrimination, which combined lead to symptoms of psychological distress and participation in risky sexual situations that increase risky sexual behaviors associated with HIV acquisition.

Sexual orientation has been shown to be a risk factor for psychiatric disorders. This study compared whether sexual orientation-related disparities in the prevalence of psychiatric disorders are similar based on homosexual behavior versus attraction and tested whether, with increased acceptance of homosexuality, these disparities have diminished over time. The Composite International Diagnostic Interview 3.0 was administered with a total of 6,646 Dutch persons, aged 18 to 64 years. Between 2.0% and 2.5% of the participants reported same-sex sexual behavior in the preceding year or same-sex attraction. Homosexually active persons and persons with same-sex attraction reported a higher prevalence of disorders than heterosexual persons. There were more disparities in the prevalence of disorders based on sexual attraction than based on sexual behavior. Comparing these results with a previous study, showed that no significant changes over time have occurred in the pattern of health disparities. Sexual orientation continues to be a risk factor for psychiatric disorders, stressing the need for understanding the origins of these disparities.

Sexual risk-taking behaviors, gambling, and heavy drinking among U.S. College athletes.

The purpose of this study was to empirically examine the prevalence patterns of sexual risk-taking behaviors (i.e., unprotected sex and having multiple sex partners) in relation to levels of gambling problems and heavy episodic drinking (HED) status among U.S. college athletes. Data from a representative national sample of 20,739 U.S. college athletes were derived from the first National Collegiate Athletic Association national survey of problem gambling and health-risk behaviors. Among college athletes who were sexually active during the past year, males reported significantly higher prevalence of unprotected sex (10.2%) and multiple sex partners (14.6%) than females (7.9% and 9.3%, respectively). Using the DSM-IV Gambling Screen classification, as the level of gambling severity increased, the prevalence of sexual risk-taking behaviors also increased among female athletes, but decreased among male athletes. As regards the effect of heavy drinking, while both male and female HED athletes reported elevated sexual risk-taking, the effect of HED was twice as large in females as in males. It is important to note that the definitions of sexual risk behaviors in this study took into account committed sexual relationship status; hence, the results of this study need to be interpreted with the refined sexual risk measures in mind. Further investigations are warranted to help us better understand and explicate the interrelationships of sexual risk-taking behaviors, gambling, and heavy drinking among these college athletes. Findings from this exploratory study suggest new directions for future research and practice and also highlight the importance of a more inclusive multi-component approach to address these co-occurring youth risk behaviors.

Latent class analysis (LCA) is a useful statistical tool that can be used to enhance understanding of how various patterns of combined sexual behavior risk factors may confer differential levels of HIV infection risk and to identify subtypes among African American adolescent girls. Data for this analysis is derived from baseline assessments completed prior to randomization in an HIV prevention trial. Participants were African American girls (n=701) aged 14-20 years presenting to sexual health clinics. Girls completed an audio computer-assisted self-interview, which assessed a range of variables regarding sexual history and current and past sexual behavior. Two latent classes were identified with the probability statistics for the two groups in this model being 0.89 and 0.88, respectively. In the final multivariate model, class 1 (the "higher risk" group; n=331) was distinguished by a higher likelihood of >5 lifetime sexual partners, having sex while high on alcohol/drugs, less frequent condom use, and history of sexually transmitted diseases (STDs), when compared with class 2 (the "lower risk" group; n=370). The derived model correctly classified 85.3% of participants into the two groups and accounted for 71% of the variance in the latent HIV-related sexual behavior risk variable. The higher risk class also had worse scores on all hypothesized correlates (e.g., self-esteem, history of sexual assault or physical abuse) relative to the lower risk class. Sexual health clinics represent a unique point of access for HIV-related sexual risk behavior intervention delivery by capitalizing on contact with adolescent girls when they present for services. Four empirically supported risk factors differentiated higher versus lower HIV risk. Replication of these findings is warranted and may offer an empirical basis for parsimonious screening recommendations for girls presenting for sexual healthcare services.

The National Social Life, Health, and Aging Project (NSHAP) was designed to examine the relationship between sexual behavior, sexual problems, and health among older women and men. We describe measures of sexual partnerships, sexual practices, sexual problems, attitudes toward sex, and nonsexual intimacy in the first wave of NSHAP. We compare measures of sexuality for those 57-85 years old, by age, separately for men and women. We construct scales of sexual mores, sexual interest, and relationship satisfaction and discuss properties of each scale. Sexuality among older adults tends to vary with age and gender. At all ages in this study, men are more likely than women to have a partner, more likely to be sexually active with that partner, and tend to have more positive and permissive attitudes toward sex. The proportions in a sexual partnership, behavior, problems, and attitudes all differ substantially by age. And these age patterns often differ for men and women. Data obtained in the NSHAP can be used to construct key measures of sexuality among older adults; to examine sexuality itself; and to explore the link between sexuality, health, well-being, and other dimensions of the lives of older adults.

The purpose of this paper is to review field studies of human male hormones and reproductive behavior. We first discuss life history theory and related conceptual considerations. As illustrations, distinctive features of human male life histories such as coalitional aggression, long-term partnering and paternal care are noted, along with their relevance to overall reproductive effort and developmental plasticity. We address broad questions about what constitutes a human male field study of hormones and behavior, including the kinds of hormone and behavioral measures employed in existing studies. Turning to several sections of empirical review, we present and discuss evidence for links between prenatal and juvenile androgens and sexual attraction and aggression. This includes the proposal that adrenal androgens-DHEA and androstenedione-may play functional roles during juvenility as part of a life-stage specific system. We next review studies of adult male testosterone responses to competition, with these studies emphasizing men's involvement in individual and team sports. These studies show that men's testosterone responses differ with respect to variables such as playing home/away, winning/losing, and motivation. Field studies of human male hormones and sexual behavior also focus on testosterone, showing some evidence of patterned changes in men's testosterone to sexual activity. Moreover, life stage-specific changes in male androgens may structure age-related differences in sexual behavior, including decreases in sexual behavior with senescence. We overview the considerable body of research on male testosterone, partnerships and paternal care, noting the variation in social context and refinements in research design. A few field studies provide insight into relationships between partnering and paternal behavior and prolactin, oxytocin, and vasopressin. In the third section of the review, we discuss patterns, limitations and directions for future research. This includes discussion of conceptual and methodological issues future research might consider as well as opportunities for contributions in under-researched male life stages (juvenility, senescence) and hormones (e.g., vasopressin).

Human immunodeficiency virus (HIV) transmission models that include variability in sexual behavior over time have shown increased incidence, prevalence, and acute-state transmission rates for a given population risk profile. This raises the question of whether dynamic variation in individual sexual behavior is a real phenomenon that can be observed and measured. To study this dynamic variation, we developed a model incorporating heterogeneity in both between-person and within-person sexual contact patterns. Using novel methodology that we call iterated filtering for longitudinal data, we fitted this model by maximum likelihood to longitudinal survey data from the Centers for Disease Control and Prevention's Collaborative HIV Seroincidence Study (1992-1995). We found evidence for individual heterogeneity in sexual behavior over time. We simulated an epidemic process and found that inclusion of empirically measured levels of dynamic variation in individual-level sexual behavior brought the theoretical predictions of HIV incidence into closer alignment with reality given the measured per-act probabilities of transmission. The methods developed here provide a framework for quantifying variation in sexual behaviors that helps in understanding the HIV epidemic among gay men.

LHRH administration is reported to facilitate male sexual behavior. The aim of the present study was to investigate whether male sexual behavior is associated with the number of LHRH neurons in the forebrain in middle-aged rats. Male Long-Evans rats (18-19 months) were assigned to three groups on the basis of sexual performance: (1) group MEI consisted of rats showing complete copulatory patterns, including mounts, intromissions and ejaculations, (2) group MI was composed of rats showing mounts and intromissions, but no ejaculation and (3) group NC were non-copulators, i.e. they did not show any copulatory behavior. Young adult rats (4-5 months), displaying sexual behavior, were used as controls. Following the sexual behavior tests, the number of LHRH neurons in the medial septum (MS), organum vasculosum of the lamina terminalis (OVLT), preoptic area (POA) and anterior hypothalamus (AH) was determined by immunocytochemistry. No difference was seen in the total number of LHRH neurons in these combined brain areas between group MIE and young controls. In the three middle-aged groups, the total number of LHRH neurons was greatest in group MIE, less in group MI, and lowest in group NC. In general, a similar trend was seen separately in the MS, OVLT and POA. These results suggest that changes in the number of LHRH neurons in the forebrain, in most cases, are age-related, at least in the middle-aged rats, but they also seem to be associated with male sexual performance.

Although transgender women are acknowledged as a priority population for HIV prevention, there is little knowledge on men who have sex with transgender women (MSTGWs). MSTGWs challenge conventional sexual orientation categories in public health and HIV prevention research, and warrant increased attention from the public health community. This paper used qualitative techniques to analyze how MSTGWs describe their sexual orientation identities, and to explore the correspondence between men's identities and sexual behaviors with transgender women. We conducted in-depth semi-structured individual interviews with 46 MSTGWs in San Francisco. We observed a diversity in the ways participants identified and explained their sexual orientation, and found no consistent patterns between how men described their sexual orientation identity versus their sexual behavior and attraction to transgender women. Findings from this qualitative study question the utility of category-based approaches to HIV prevention with MSTGWs and offer insights into developing HIV interventions for these men.

Pedophilia refers to the recurrent, intense sexual interest in prepubescent children who, by definition, have not developed any secondary sex characteristics. Researchers have begun to investigate whether persons with pedophilia are qualitatively different from those without pedophilia (pedophilia is a taxon) or if people vary in their level of sexual interest toward children (pedophilia is dimensional). Two relatively small studies have previously attempted to address this question, but produced conflicting results. The present study built on these studies with a substantially larger sample of 2,227 men who committed sexual offenses and were assessed at a sexual behavior clinic. The present study also examined a broader range of measures more closely approximating the diagnostic criteria for pedophilic disorder, including phallometric assessment of sexual arousal patterns. The results of 3 taxometric analyses did not find support for the assertion that pedophilia is a taxon. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Technological advancements and Internet sexuality: does private access to the Internet influence online sexual behavior?

The aim of this study was to investigate whether demographic characteristics and sexual behavior online and offline were associated with private, respectively, nonprivate access to the Internet in a Web sample of people who use the Internet for sexual purposes. A total of 1,913 respondents completed an online questionnaire about Internet sexuality, and 1,614 reported using the Internet for sexual purposes. The majority of these respondents reported having access to an Internet-connected computer no one else had access to (62 percent women and 70 percent men). The results showed that it is possible to differentiate between those who have access to an Internet-connected computer no one else has access to and those who have shared access to an Internet-connected computer. Not only did they differ in demographic characteristics, but also in the sexual activities they engaged in on the Internet. Different patterns were found for women and men. For example, men who had private access to Internet-connected computers were more likely than those who had shared access to seek information about sexual issues. Thus, having access to Internet computers no one else has access to may promote sexual knowledge and health for men. The results of this study along with the technological development implies that in future research, attention should be paid to where and how people access the Internet in relation to online behavior in general and online sexual behavior in particular.

Neurobehavioral models of pedophilia and child sexual offending suggest a pattern of temporal and in particular prefrontal disturbances leading to inappropriate behavioral control and subsequently an increased propensity to sexually offend against children. However, clear empirical evidence for such mechanisms is still missing. Using a go/nogo paradigm in combination with functional magnetic resonance imaging (fMRI) we compared behavioral performance and neural response patterns among three groups of men matched for age and IQ: pedophiles with (N = 40) and without (N = 37) a history of hands-on sexual offences against children as well as healthy non-offending controls (N = 40). As compared to offending pedophiles, non-offending pedophiles exhibited superior inhibitory control as reflected by significantly lower rate of commission errors. Group-by-condition interaction analysis also revealed inhibition-related activation in the left posterior cingulate and the left superior frontal cortex that distinguished between offending and non-offending pedophiles, while no significant differences were found between pedophiles and healthy controls. Both areas showing distinct activation pattern among pedophiles play a critical role in linking neural networks that relate to effective cognitive functioning. Data therefore suggest that heightened inhibition-related recruitment of these areas as well as decreased amount of commission errors is related to better inhibitory control in pedophiles who successfully avoid committing hands-on sexual offences against children.

Although research has long documented the relevance of gender for health, studies that simultaneously incorporate the relevance of disparate sexual orientation groups are sparse. We address these shortcomings by applying an intersectional perspective to evaluate how sexual orientation and gender intersect to pattern self-rated health status among U.S. adults. Our project aggregated probability samples from the Behavioral Risk Factor Surveillance System (BRFSS) across seven U.S. states between 2005 and 2010, resulting in an analytic sample of 10,128 sexual minority (gay, lesbian, and bisexual) and 405,145 heterosexual adults. Logistic regression models and corresponding predicted probabilities examined how poor self-rated health differed across sexual orientation-by-gender groups, before and after adjustment for established health risk factors. Results reveal distinct patterns among sexual minorities. Initially, bisexual men and women reported the highest--and gay and lesbian adults reported the lowest--rates of poor self-rated health, with heterosexuals in between. Distinct socioeconomic status profiles accounted for large portions of these differences. Furthermore, in baseline and fully adjusted regression models, only among heterosexuals did women report significantly different health from men. Importantly, the findings highlight elevated rates of poor health experienced by bisexual men and women, which are partially attributable to their heightened economic, behavioral, and social disadvantages relative to other groups.

Rethinking Sexual Initiation: Pathways to Identity Formation among Gay and Bisexual Mexican Male Youth

Carrillo, Héctor; Fontdevila, Jorge

2010-01-01

The topic of same-sex sexual initiation has generally remained understudied in the literature on sexual identity formation among sexual minority youth. This article analyzed the narratives of same-sex sexual initiation provided by 76 gay and bisexual Mexican immigrant men who participated in interviews for the Trayectos Study, an ethnographic study of sexuality and HIV risk. These participants were raised in a variety of locations throughout Mexico, where they also realized their same-sex attraction and initiated their sexual lives with men. We argue that Mexican male same-sex sexuality is characterized by three distinct patterns of sexual initiation-- one heavily-based on gender roles, one based on homosociality, and one based on object choice-- which inform the men’s interpretations regarding sexual roles, partner preferences, and sexual behaviors. We analyzed the social factors and forms of cultural/sexual socialization that lead sexual minority youth specifically to each of these three patterns of sexual initiation. Our findings confirm the importance of studying same-sex sexual initiation as a topic in its own right, particularly as a tool to gain a greater understanding of the diversity of same-sex sexual experiences and sexual identities within and among ethnic/cultural groups.

The viewing of sexually explicit media (SEM) is widespread, especially among men, and research linking SEM viewing and sexual behavior has shown a variety of results, some positive (e.g., sexuality education) and some negative (e.g., poorer body image). These results might be due to limitations in measuring SEM consumption, particularly around typology. The goal of the current study was to examine potential patterns of SEM viewing activities. Using data from an online survey of men who have sex with men (MSM), we conducted latent class analyses of 15 SEM activities. Results suggested a three-class solution. The most prevalent class included over 60% of men and was characterized by viewing primarily safer-sex or conventional behaviors. The second class included 32% of men and had a similar albeit amplified pattern of viewing. The final class included just 7% of men and was marked by high levels of viewing of all activities, including fetish and kink. Compared to the conventional or safer-sex class, the other classes had lower internalized homonegativity, lower condom use self-efficacy, and higher SEM consumption or dose. Implications for HIV prevention, sexuality research and the SEM industry are discussed. PMID:25642301

Background Although humans experience orgasms with a degree of statistical regularity, they remain among the most enigmatic of sexual responses; difficult to define and even more difficult to study empirically. The question of whether animals experience orgasms is hampered by similar lack of definition and the additional necessity of making inferences from behavioral responses. Method Here we define three behavioral criteria, based on dimensions of the subjective experience of human orgasms described by Mah and Binik, to infer orgasm-like responses (OLRs) in other species: 1) physiological criteria that include pelvic floor and anal muscle contractions that stimulate seminal emission and/or ejaculation in the male, or that stimulate uterine and cervical contractions in the female; 2) short-term behavioral changes that reflect immediate awareness of a pleasurable hedonic reward state during copulation; and 3) long-term behavioral changes that depend on the reward state induced by the OLR, including sexual satiety, the strengthening of patterns of sexual arousal and desire in subsequent copulations, and the generation of conditioned place and partner preferences for contextual and partner-related cues associated with the reward state. We then examine whether physiological and behavioral data from observations of male and female rats during copulation, and in sexually-conditioned place- and partner-preference paradigms, are consistent with these criteria. Results Both male and female rats display behavioral patterns consistent with OLRs. Conclusions The ability to infer OLRs in rats offers new possibilities to study the phenomenon in neurobiological and molecular detail, and to provide both comparative and translational perspectives that would be useful for both basic and clinical research.

Sexual variation in India: A view from the west

Sexual variation has been reported across cultures for millennia. Sexual variation deals with those facets of sexual behavior which are not necessarily pathological. It is any given culture that defines what is abnormal and what is deviant. In scriptures, literature and poetry in India same sex love has been described and explained in a number of ways. In this paper we highlight homosexual behavior and the role of hijras in the Indian society, among other variations. These are not mental illnesses and these individuals are not mentally ill. Hence the role of psychiatry and psychiatrists has to be re-evaluated. Attitudes of the society and the individual clinicians may stigmatize these individuals and their behavior patterns. Indian psychiatry in recent times has made some progress in this field in challenging attitudes, but more needs to be done in the 21st century. We review the evidence and the existing literature.

Until now, research on sexual behavior and HIV in Israel has been carried out mainly on the general population, and focused primarily on defining populations at risk, without adequate consideration given to the reasons bringing these populations to be tested, and their specific sexual behaviors. In Israel, one can choose whether to take an HIV test in confidential centers (giving one's name under medical confidentiality) or in anonymous centers (Israel AIDS Task Force in Tel Aviv and Beer Sheva, Levinsky Clinic in Tel Aviv and Haparsim Clinic in Haifa]. At least 21% of the clients of the anonymous testing centers in Israel belong to a high risk population in contrast to 2.6% in confidential clinics, and so, in this study, we hypothesize that characterization of sexual behavior patterns in anonymous testing centers might enable us to better characterize sexual behavior patterns in high risk populations. In this cross-sectional study, we used questionnaires distributed in the clinics by the Israel AIDS Task Force in order to characterize their clinic's clients. The questionnaires were completed by the Israel AIDS Task Force consultants during the consultation period at which the anonymous test was performed. Data collected included: gender, age, testing history, specific sexual behaviors and reasons for applying for the current test. A total of 926 questionnaires were collected; 29.9% of them were of female patients. The average age was 29.47 years (1±8.66]; 21.3% of the clients were men who have sex with men [MSM]; only 2.3% of the clients belonged to other high risk populations. In all groups, the majority of the patients reported high risk sexual behavior (any sexual contact without a condom) and the average age for the first test was much higher than the average age of first sexual intercourse common in Israel. Women reported more participation in unprotected vaginal intercourse than heterosexual men, and a substantial part of MSM reported performing unprotected anal intercourse. More heterosexuals than MSM stated a new relationship as a reason for applying for the test, and more MSM than heterosexuals reported arriving for a routine check-up. There is a need for comprehensive programs encouraging testing for HIV in all age groups, focusing on Sthe ages 18-25 years, and encouraging the use of a condom as a preventive measure in all populations, especially women. We feel it is essential to emphasize the need for educational programs tailored for each sub-population's psychosocial characteristics and specific issues.

Although the prevalence of human immunodeficiency virus (HIV) decreased in the last decade worldwide, the number of deaths due to HIV/AIDS and communicable diseases including syphilis, hepatitis, and tuberculosis had dramatically increased in developing countries. Education and behavior are incredibly important factors to prevent these diseases' spread. This study highlights the range of differences in knowledge, attitude, and behavior of 434 sexually active medical students towards HIV/AIDS and sexually transmitted infections (STIs). Because the surveyed population constitutes the forefront of healthcare providers and was originated from different area of the world, this is the first time a study sought to investigate the behavioral attitude of this group of population irrespective of the three levels of their academic and professional knowledge. Several factors including sociodemographic characteristics, sexual behavior, HIV/AIDS, and STIs related patterns play a key role in medical student attitude and behavior towards people infected with HIV/AIDS and STIs. Our findings add consistent value in prior studies which aimed to stop new infections and also imply further investigations on the management of the studied infections by medical students. The present study arouses much interest among participants and provides evidence of reinforcing medical students' education on HIV/AIDS and STIs.

Parent-based HIV prevention programming may play an important role in reaching youths early to help establish lifelong patterns of safe and healthy sexual behaviors. Families Matter! is a 5-session, evidence-based behavioral intervention designed for primary caregivers of children aged 9 to 12 years to promote positive parenting and effective parent–child communication about sexuality and sexual risk reduction. The program’s 5-step capacity-building model was implemented with local government, community, and faith-based partners in 8 sub-Saharan African countries with good intervention fidelity and high levels of participant retention. Families Matter! may be useful in other resource-constrained settings. PMID:24028229

Hypersexuality: A Critical Review and Introduction to the "Sexhavior Cycle".

Walton, Michael T; Cantor, James M; Bhullar, Navjot; Lykins, Amy D

2017-11-01

An empirical review of hypersexuality is timely as "compulsive sexual behavior" is being considered as an impulse control disorder for inclusion in the forthcoming International Classification of Diseases, 11th ed. Specifically, hypersexuality has been conceptualized in the literature as the inability to regulate one's sexual behavior that is a source of significant personal distress. Various theoretical models have been posited in an attempt to understand the occurrence of hypersexuality, although disagreement about these divergent conceptualizations of the condition has made assessment and treatment of hypersexual clients more challenging. Theories of sexual compulsivity, sexual impulsivity, dual control (sexual inhibition/excitation), and sex addiction are critically examined, as are the diagnostic criteria for clinically assessing hypersexuality as a sexual disorder. Our discussion of hypersexuality covers a diversity of research and clinical perspectives. We also address various challenges associated with reliably defining, psychometrically measuring, and diagnosing hypersexuality. Furthermore, literature is reviewed that expresses concerns regarding whether hypersexuality (conceptualized as a disorder) exists, whether it is simply normophilic behavior at the extreme end of sexual functioning, or alternatively is a presenting problem that requires treatment rather than a clinical diagnosis. Following our literature review, we developed the "sexhavior cycle of hypersexuality" to potentially explain the neuropsychology and maintenance cycle of hypersexuality. The sexhavior cycle suggests that, for some hypersexual persons, high sexual arousal may temporarily and adversely impact cognitive processing (cognitive abeyance) and explain a repeated pattern of psychological distress when interpreting one's sexual behavior (sexual incongruence). We also suggest that further research is required to validate whether hypersexuality is a behavioral disorder (such as gambling), although some presentations of the condition appear to be symptomatic of a heterogeneous psychological problem that requires treatment.

Differences in gay men's AIDS risk knowledge and behavior patterns in high and low AIDS prevalence cities.

Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters. PMID:2502813

This study characterized rates of sexual activity and identified psychosocial and behavioral correlates of sexual activity and condom use in a metropolitan sample of 290 HIV-infected adults 50-plus years of age. Thirty-eight percent of participants were sexually active in the past three months, 33% of whom had at least one occasion of anal or vaginal intercourse that was not condom protected. Rates and correlates of sexual activity and condom use differed between gay/bisexual men, heterosexual men, and heterosexual women. In the past three months, 72% of heterosexual men were sexually active compared to only 36% of gay/bisexual men and 21% of heterosexual women. However, among sexually active persons, only 27% of heterosexual men reported inconsistent condom use compared to 37% of gay/bisexual men and 35% of heterosexual women. As the number of older adults living with HIV/AIDS in the U.S. continues to increase, age-appropriate secondary risk-reduction interventions are urgently needed. PMID:18389361

Cichlid fishes of Lake Tanganyika display a variety of mating and parental care behaviors, including polygamous and monogamous mouthbrooding and substrate breeding, cooperative breeding, as well as various alternative reproductive tactics such as sneaking and piracy. Moreover, reproductive behaviors sometimes vary within species both in space and in time. Here, I survey reports on mating and parenting behaviors of Lake Tanganyika cichlid species and address the evolution of mating and parental care patterns and sexual dimorphism. Notes on measures of sexual selection intensity and the difficulties of defining mating systems and estimating selection intensities at species level conclude the essay. PMID:21822482

Adverse Childhood Environment: Relationship With Sexual Risk Behaviors and Marital Status in a Large American Sample.

PubMed

Anderson, Kermyt G

2017-01-01

A substantial theoretical and empirical literature suggests that stressful events in childhood influence the timing and patterning of subsequent sexual and reproductive behaviors. Stressful childhood environments have been predicted to produce a life history strategy in which adults are oriented more toward short-term mating behaviors and less toward behaviors consistent with longevity. This article tests the hypothesis that adverse childhood environment will predict adult outcomes in two areas: risky sexual behavior (engagement in sexual risk behavior or having taken an HIV test) and marital status (currently married vs. never married, divorced, or a member of an unmarried couple). Data come from the Behavioral Risk Factor Surveillance System. The sample contains 17,530 men and 23,978 women aged 18-54 years living in 13 U.S. states plus the District of Columbia. Adverse childhood environment is assessed through 11 retrospective measures of childhood environment, including having grown up with someone who was depressed or mentally ill, who was an alcoholic, who used or abused drugs, or who served time in prison; whether one's parents divorced in childhood; and two scales measuring childhood exposure to violence and to sexual trauma. The results indicate that adverse childhood environment is associated with increased likelihood of engaging in sexual risk behaviors or taking an HIV test, and increased likelihood of being in an unmarried couple or divorced/separated, for both men and women. The predictions are supported by the data, lending further support to the hypothesis that childhood environments influence adult reproductive strategy.

Objectives The National Social Life, Health, and Aging Project (NSHAP) was designed to examine the relationship between sexual behavior, sexual problems, and health among older women and men. We describe measures of sexual partnerships, sexual practices, sexual problems, attitudes toward sex, and nonsexual intimacy in the first wave of NSHAP. Methods We compare measures of sexuality for those 57–85 years old, by age, separately for men and women. We construct scales of sexual mores, sexual interest, and relationship satisfaction and discuss properties of each scale. Results Sexuality among older adults tends to vary with age and gender. At all ages in this study, men are more likely than women to have a partner, more likely to be sexually active with that partner, and tend to have more positive and permissive attitudes toward sex. The proportions in a sexual partnership, behavior, problems, and attitudes all differ substantially by age. And these age patterns often differ for men and women. Discussion Data obtained in the NSHAP can be used to construct key measures of sexuality among older adults; to examine sexuality itself; and to explore the link between sexuality, health, well-being, and other dimensions of the lives of older adults.

"Excessive" viewing of visual sexual stimuli (VSS) is the most commonly reported hypersexual behavior problem and is especially amenable to laboratory study. A pattern of enhanced sexual cue responsiveness is expected in this sample if hypersexuality shares features of other addiction models. Participants (N=122) who either reported or denied problematic VSS use were presented with emotional, including explicit sexual, images while their evoked response potentials were recorded. An interaction of hypersexual problem group and the level of desire for sex with a partner predicted LPP amplitude. Specifically, those reporting problems regulating their VSS use who also reported higher sexual desire had lower LPP in response to VSS. This pattern appears different from substance addiction models. These are the first functional physiological data of persons reporting VSS regulation problems. Copyright © 2015 Elsevier B.V.

This study was conducted to assess the magnitude and pattern of sexual abuse among male inmates of an observation home in Delhi. A total of 189 boys aged 6 to 18 years were assessed for sexual abuse using Finkelhors scale and Child Maltreatment History Self-Report followed by clinical examination using American Medical Associations guidelines. Majority of boys were runaways and 38.1 percent had suffered sexual abuse. On clinical examination, 61.1 percent showed physical signs and 40.2 percent showed behavioral signs of sexual abuse. Forcible sex was reported by 44.4 percent of victims and 25 percent had signs suggestive of sexually transmitted diseases. Strangers were the most common perpetrators of sexual abuse.

2009-10-01

We asked 298 heterosexual Canadian university students about their definitions of the terms abstinence and having sex. For both terms, students were provided with a list of 17 sexual behaviors and indicated whether they would include each in their definition. The majority of both male and female students included activities that did not involve genital stimulation in their definition of sexual abstinence and did not include these activities in their definition of having sex. Conversely, most students did not include bidirectional sexual stimulation (penile-vaginal intercourse or penile-anal intercourse) in their definitions of sexual abstinence but did include them in their definitions of having sex. Students were quite mixed in whether activities involving unidirectional genital stimulation (e.g., oral sex, genital fondling) constituted abstinence, having sex, or neither abstinence nor having sex. However, they were more likely to see these behaviors as abstinent than as having sex. Students were more likely to rate a behavior as abstinence if orgasm did not occur. A canonical correlation analysis was used to examine the patterns of association between a number of predictors and inclusions of behaviors involving no genital stimulation, unidirectional stimulation, and bidirectional genital stimulation in abstinence definitions. The results indicated that male participants who were more involved with their religion and sexually conservative, less sexually experienced, and who had not received sexual health education at home were more likely to define bidirectional genital stimulation and less likely to define no genital stimulation and unidirectional sexual stimulation as sexual abstinence. The research and health promotion implications of these results are discussed.

Is sexual motivational state linked to dopamine release in the medial preoptic area?

PubMed

Kleitz-Nelson, H K; Dominguez, J M; Cornil, C A; Ball, G F

2010-04-01

The medial preoptic area (mPOA) is a key site for the dopaminergic enhancement of male sexual behavior. Dopamine release increases in the rat mPOA with mating, supporting the critical stimulatory role played by preoptic dopamine on male sexual behavior. However, it has been questioned whether dopamine is specifically related to the occurrence of male sexual behavior and not simply involved in general arousal. To address this question, we asked whether dopamine release in the mPOA is linked to the production of male sexual behavior in Japanese quail (Coturnix japonica), a species that exhibits a much shorter temporal pattern of copulation than rats and does not have an intermittent organ, resulting in a very different topography of their sexual response. Extracellular samples from the mPOA of adult sexually experienced male quail were collected every 6 min before, during, and after exposure to a female using in vivo microdialysis and analyzed using high-performance liquid chromatography with electrochemical detection. Extracellular dopamine significantly increased in the presence of a female and returned to baseline after removal of the female. However, quail that failed to copulate did not display this increased release. These findings indicate that it is not solely the presence of a female that drives dopamine release in males, but how a male responds to her. Furthermore, in quail that copulated, dopamine release did not change in samples collected during periods of no copulation. Together, these findings support the hypothesis that dopamine action in the mPOA is specifically linked to sexual motivation and not only to copulatory behavior or physical arousal.

The purpose of this study was to investigate consumption patterns of gay-oriented sexually explicit media (SEM) among men who have sex with men (MSM) in Norway, with a particular emphasis on a possible relationship between gay SEM consumption and HIV risk behavior. Participants included 529 MSM living in Norway recruited online to complete a SEM consumption and sexual risk survey. Of the 507 participants who responded to the all items measuring exposure to SEM, 19% reported unprotected anal intercourse with a casual partner (UAI) in last 90 days, and 14% reported having had sero-discordant UAI. Among those with UAI experience, 23% reported receptive anal intercourse (R-UAI) and 37% reported insertive anal intercourse (I-UAI). SEM consumption was found to be significantly associated with sexual risk behaviors. Participants with increased consumption of bareback SEM reported higher odds of UAI and I-UAI after adjusting for other factors using multivariable statistics. MSM who started using SEM at a later age reported lower odds of UAI and I-UAI than MSM who started earlier. Future research should aim at understanding how MSM develop and maintain SEM preferences and the relationship between developmental and maintenance factors and HIV sexual risk behavior.

Sex, politics, and social change in the eighteenth and the nineteenth centuries: evidence from the Swiss Alps.

PubMed

Guzzi-Heeb, Sandro

2011-01-01

The eighteenth-century "sexual revolution" cannot simply be explained as a consequence of economic or institutional factors -- industrialization, agricultural revolution, secularization, or legal hindrances to marriages. The example of western Valais (Switzerland) shows that we have to deal with a complex configuration of factors. The micro-historical approach reveals that in the eighteenth- and nineteenth-century sexuality -- and above all illicit sexuality -- was a highly subversive force that was considerably linked to political innovation and probably more generally to historical change. Nonmarital sexuality was clearly tied to political dissent and to innovative ways of behavior, both among the social elites and the common people. This behavior patterns influenced crucial evolutions in the social, cultural, and economic history of the region.

The organizational effects of pubertal testosterone on sexual proficiency in adult male Syrian hamsters.

PubMed

De Lorme, Kayla C; Sisk, Cheryl L

2016-10-15

Social proficiency requires making appropriate behavioral adaptations as a result of social experience. For example, male rodents become sexually proficient with experience as demonstrated by a reduction in ectopic (misdirected) mounts, mount-to-intromission ratio, and latency to ejaculation. We previously found that over a series of timed tests with a receptive female, male hamsters deprived of testosterone specifically during puberty (NoT@P) have overall lower levels of sexual behavior and continue to display high levels of ectopic mounts, compared with males that experienced endogenous testosterone during puberty (T@P). These results suggested that pubertal testosterone programs sexual proficiency in adulthood, but because NoT@P males engaged in less sexual behavior than T@P males in these tests, the amount of sexual experience may have been insufficient to improve sexual proficiency. To more rigorously test the hypothesis that pubertal testosterone is necessary for social proficiency in adulthood, the present study compared the behavior of NoT@P and T@P males in a series of 4 trials with a 48-h interval between each trial. Sexual experience was equated by limiting each trial to 5 intromissions. Sexually-naïve males were either gonadectomized prepubertally (NoT@P) or in adulthood (T@P) and received subcutaneous testosterone capsules four weeks later. Two weeks after testosterone replacement, these groups and a group of adult gonad-intact controls began sexual behavior testing. We found that NoT@P males had more ectopic mounts/min across all four tests compared to gonad-intact and T@P males. Moreover, both gonad-intact and T@P males, but not NoT@P males, showed an increase in the number of mounts and intromissions/min between trials 1 and 3. Unexpectedly, both gonad-intact and T@P, but not NoT@P, males showed a decrease in sexual behaviors during trial 4. Thus, T@P males display multiple behavioral adaptations to sexual experience that are not observed in NoT@P males: a reduction in ectopic mounts after repeated encounters with a receptive female and an inverted U-shape pattern in mounts and intromissions when these encounters do not lead to ejaculations. These results support the hypothesis that pubertal testosterone organizes neural circuits underlying behavioral flexibility and adaptability to promote sexual proficiency in adulthood.

This paper presents the profile and experience of sexuality generated from a data mining classification task. We used a database about sexuality and gender violence performed on a university population in southern Brazil. The data mining task identified two relationships between the variables, which enabled the distinction of subgroups that better detail the profile and experience of sexuality. The identification of the relationships between the variables define behavioral models and factors of risk that will help define the algorithms being implemented in the data mining classification task.

Sexual behavior, reproductive physiology and sperm competition in male mammals.

PubMed

Dixson, Alan F; Anderson, Matthew J

2004-11-15

Sperm competition involves competition between the gametes of two or more males of a species for fertilization of a given set of ova. Sperm competition is widespread among mammals, as in many other groups of vertebrates. Effects of sexual selection, via sperm competition, upon the evolution of reproductive physiology and behavior are much better understood in invertebrates (and especially in insects) than is the case for mammals. However, if the reproductive organs of male mammals are viewed as an integrated system for production and delivery of spermatozoa (and accessory glandular secretions) to females, then it is logical to assume that sperm competition might influence the evolution of all parts of the system, as well as associated physiological mechanisms (e.g., testicular endocrinology) and behavior (e.g., copulatory patterns). Here we analyze and review relationships between mating systems, relative testes sizes and sperm morphology, phallic morphology, circulating testosterone levels and sexual behavior in male mammals.

Religious Attendance as Reproductive Support

PubMed Central

Weeden, Jason; Cohen, Adam B.; Kenrick, Douglas T.

2009-01-01

We argue that a central function of religious attendance in the contemporary U.S. is to support a high-fertility, monogamous mating strategy. Although religious attendance is correlated with many demographic, personality, moral, and behavioral variables, we propose that sexual and family variables are at the core of many of these relationships. Numerous researchers have assumed that religious socialization causes people to feel moral reactions and engage in behaviors promoted by religious groups. On our view, mating preferences are centrally involved in individual differences in attraction to religious groups. In a sample of 21,131 individuals who participated in the U.S. General Social Survey, sexual behaviors were the relatively strongest predictors of religious attendance, even after controlling for age and gender. Effects of age and gender on religious attendance were weaker, and substantially reduced when controlling for sexual and family patterns. A sample of 902 college students provided more detailed information on religious, moral, and sexual variables. Results suggest that 1) moral views about sexual behavior are more strongly linked to religious attendance than other moral issues, and 2) mating strategy is more powerful than standard personality variables in predicting religious attendance. These findings suggest that reproductive strategies are at the heart of variations in religious attendance. PMID:21874105

Evolutionary psychology accounts of gender differences in sexual behaviors in general and men's sexual aggression, in particular, has been criticized for legitimizing males' sexual misconduct. To empirically assess such critiques, two studies examined how men's judgments of male sex crimes (solicitation of sex from a prostitute; rape) are influenced by exposure to (a) evolutionary psychological theories and (b) social-constructivist theories. Across two studies, a consistent pattern emerged compared with a control condition (a) exposure to evolutionary psychology theories had no observable impact on male judgments of men's criminal sexual behavior, whereas (b) exposure to social-constructivist theories did affect judgments, leading men to evaluate sex crimes more harshly. Additional results (from Study 2) indicate that this effect is mediated by perceptions of male control over sexual urges. These results have implications for journalists, educators, and scientists.

Background Problem Behavior Theory posits that risky behaviors cluster in individuals, implying that protective behaviors may follow a similar pattern. The purpose of this study was to determine whether the protective behavior of effective dual method contraception use at first and most recent sexual intercourse is associated with HPV vaccination among adolescent and young adult females. Methods National Survey of Family Growth (2006–2010) data were used to examine the association between women’s contraception use during first and most recent sexual intercourse and HPV vaccination. Women aged 15 to 24 years (n = 1,820) served as the study sample. Findings At first and last sexual intercourse, effective dual method contraception use was reported by 15.3% and 16.8% women, respectively; 27.8% reported receiving at least one dose of the human papillomavirus (HPV) vaccine. Higher HPV vaccination rates were observed among dual method users at first and last sexual intercourse (36.4% and 48.2%, respectively). This trend was also observed across age groups (15–19 year olds vs. 20–24 year olds). In adjusted models, among all respondents, dual users at last sexual intercourse were significantly more likely to be vaccinated, whereas at first sexual intercourse only younger dual users were more likely to report HPV vaccination. Conclusions Findings suggest that the protective behavior of dual method contraceptive use at first and most recent sexual intercourse may serve as a predictor of another complementary health behavior, HPV vaccination, particularly among adolescent females. More research is needed to understand behavioral clustering to design related multi-focused women’s health interventions. PMID:25213746

So far, a recognizable pattern of clinical symptoms for child sexual abuse (CSA), especially in young male children, is lacking. To improve early recognition of CSA, we reviewed physical complaints, physical examination, and tests on sexually transmitted infections (STIs) in confirmed victims (predominantly preschool boys) of CSA from the Amsterdam sexual abuse case (ASAC). We retrospectively analyzed the outcomes of the primary assessment using mixed methods: descriptive analysis of physical complaints, physical exams, and STI tests from medical files and a qualitative analysis on expert's interpretations of physical complaints and children's behavior during physical examination. We included 54 confirmed CSA victims, median age 3.2 (0-6) years, 43 boys (80%), and 11 girls (20%). Physical complaints were reported in 50%, of which gastrointestinal and anogenital complaints were most common. None of the children showed CSA-specific genital signs at physical examination. Most prominent finding during physical examination was a deviant behavioral response (anxiety, withdrawal, too outgoing) in 15 children (28%), especially in children who experienced anal/vaginal penetration. Testing for STIs was negative. Physical complaints and physical signs at examinations were non-specific for CSA. Deviant behavioral reactions during physical examination were the most prominent finding. Precise observation of a child's behavior during physical examination is needed. What is known • Child sexual abuse (CSA) affects many children on both the short and the long term but remains unrecognized in most cases. • So far, there is a lack of studies on symptom patterns of CSA in male, preschool children. What is new • None of the children showed CSA-specific findings at physical and anogenital examination; STIs were not found in the confirmed victims of CSA. • The most prominent finding was the deviant behavioral response of the children examined, especially in children who experienced anal/vaginal penetration; therefore, precise observation of a child's behavior during physical examination is a crucial part of the evaluation of suspected CSA.

Patterns of physical and psychological teen dating violence (TDV) perpetration, victimization, and related behaviors were examined with data from the evaluation of the Start Strong: Building Healthy Teen Relationships initiative, a dating violence primary prevention program targeting middle school students. Latent class and latent transition models were used to estimate distinct patterns of TDV and related behaviors of bullying and sexual harassment in seventh grade students at baseline and to estimate transition probabilities from one pattern of behavior to another at the 1-year follow-up. Intervention effects were estimated by conditioning transitions on exposure to Start Strong. Latent class analyses suggested four classes best captured patterns of these interrelated behaviors. Classes were characterized by elevated perpetration and victimization on most behaviors (the multiproblem class), bullying perpetration/victimization and sexual harassment victimization (the bully-harassment victimization class), bullying perpetration/victimization and psychological TDV victimization (bully-psychological victimization), and experience of bully victimization (bully victimization). Latent transition models indicated greater stability of class membership in the comparison group. Intervention students were less likely to transition to the most problematic pattern and more likely to transition to the least problem class. Although Start Strong has not been found to significantly change TDV, alternative evaluation models may find important differences. Latent transition analysis models suggest positive intervention impact, especially for the transitions at the most and the least positive end of the spectrum. Copyright © 2015.

YOUNG ADULT DATING RELATIONSHIPS AND THE MANAGEMENT OF SEXUAL RISK

2012-01-01

Young adult involvement in sexual behavior typically occurs within a relationship context, but we know little about the ways in which specific features of romantic relationships influence sexual decision-making. Prior work on sexual risk taking focuses attention on health issues rather than relationship dynamics. We draw on data from the Toledo Adolescent Relationships Study (TARS) (n = 475) to examine the association between qualities and dynamics of current/most recent romantic relationships such as communication and emotional processes, conflict, demographic asymmetries, and duration and the management of sexual risk. We conceptualize ‘risk management’ as encompassing multiple domains, including (1) questioning the partner about previous sexual behaviors/risks, (2) using condoms consistently, and (3) maintaining sexual exclusivity within the relationship. We identify distinct patterns of risk management among dating young adults and find that specific qualities and dynamics of these relationships are linked to variations in risk management. Results from this paper suggest the need to consider relational dynamics in efforts to target and influence young adult sexual risk-taking and reduce STIs, including HIV. PMID:23805015

To provide a foundation for those who provide sexual health services and programs to men in the United States, the need for population-based data that describes men's sexual behaviors and their correlates remains. The purpose of this study was to, in a national probability survey of men ages 18-94 years, assess the occurrence and frequency of sexual behaviors and their associations with relationship status and health status. A national probability sample of 2,522 men aged 18 to 94 completed a cross-sectional survey about their sexual behaviors, relationship status, and health. Relationship status; health status; experience of solo masturbation, partnered masturbation, giving oral sex, receiving oral sex, vaginal intercourse and anal intercourse, in the past 90 days; frequency of solo masturbation, vaginal intercourse and anal intercourse in the past year. Masturbation, oral intercourse, and vaginal intercourse are prevalent among men throughout most of their adult life, with both occurrence and frequency varying with age and as functions of relationship type and physical health status. Masturbation is prevalent and frequent across various stages of life and for both those with and without a relational partner, with fewer men with fair to poor health reporting recent masturbation. Patterns of giving oral sex to a female partner were similar to those for receiving oral sex. Vaginal intercourse in the past 90 days was more prevalent among men in their late 20s and 30s than in the other age groups, although being reported by approximately 50% of men in the sixth and seventh decades of life. Anal intercourse and sexual interactions with other men were less common than all other sexual behaviors. Contemporary men in the United States engage in diverse solo and partnered sexual activities; however, sexual behavior is less common and more infrequent among older age cohorts. © 2010 International Society for Sexual Medicine.

Sexual selection modulates genetic conflicts and patterns of genomic imprinting

PubMed Central

Faria, Gonçalo S.; Varela, Susana A. M.; Gardner, Andy

2017-01-01

Recent years have seen a surge of interest in linking the theories of kin selection and sexual selection. In particular, there is a growing appreciation that kin selection, arising through demographic factors such as sex‐biased dispersal, may modulate sexual conflicts, including in the context of male–female arms races characterized by coevolutionary cycles. However, evolutionary conflicts of interest need not only occur between individuals, but may also occur within individuals, and sex‐specific demography is known to foment such intragenomic conflict in relation to social behavior. Whether and how this logic holds in the context of sexual conflict—and, in particular, in relation to coevolutionary cycles—remains obscure. We develop a kin‐selection model to investigate the interests of different genes involved in sexual and intragenomic conflict, and we show that consideration of these conflicting interests yields novel predictions concerning parent‐of‐origin specific patterns of gene expression and the detrimental effects of different classes of mutation and epimutation at loci underpinning sexually selected phenotypes.

The objective of this study was to explore patterns of drug use and sexual risk behaviors among people who inject drugs (PWID) in Iran. We surveyed 500 PWID in Kermanshah concerning demographic characteristics, sexual risk behaviors, and drug-related risk behaviors in the month prior to study. We used latent class analysis (LCA) to establish a baseline model of risk profiles and to identify the optimal number of latent classes, and we used ordinal regression to identify factors associated with class membership. Three classes of multiple HIV risk were identified. The probability of membership in the high-risk class was 0.33, compared to 0.26 and 0.40 for the low- and moderate-risk classes, respectively. Compared to members in the lowest-risk class (reference group), the highest-risk class members had higher odds of being homeless (OR = 4.5, CI: 1.44-8.22; p = 0.001) in the past 12 months. Members of the high-risk class had lower odds of regularly visiting a needle and syringe exchange program as compared to the lowest-risk class members (AOR = 0.42, CI: 0.2-0.81; p = 0.01). Findings show the sexual and drug-related HIV risk clusters among PWID in Iran, and emphasize the importance of developing targeted prevention and harm reduction programs for all domains of risk behaviors, both sexual and drug use related.

Background and aims Compulsive sexual behaviors (CSBs) are an important clinical and social issue. Despite the increasing number of studies, some of CSB's aspects remain under-investigated. Here, we explore the nature of CSB, such as binge pornography use and masturbation (PuM), and verify the correspondence between self-perceived factors leading to such behavior with its measures obtained in a diary assessment. Methods Semi-structuralized interviews with nine treatment-seeking males aged 22-37 years (M = 31.7, SD = 4.85) were followed by a questionnaire and a 10-week-long diary assessment, allowing us to acquire real-life daily patterns of CSB. Results Six out of nine subjects experienced binge (multiple hours or times a day) PuM. All subjects presented a high level of anxiety and perceived PuM as a way to regulate mood and stress. Data collected in the diary assessment uncovered a high diversity in the patterns of sexual behaviors (such as frequency of regular and binge PuM) and its correlates. Binge PuM was related to decreased mood and/or increased stress or anxiety. The causal relation between these correlates remains undetermined. Discussion and conclusions Binge PuM seems to be one of the most characteristic behavior among males who are seeking treatment for CSB and is related to the feeling of losing control over one's sexual activity. CSB individuals indicate a variety of binge triggers. Also, diary assessment data indicate that specific correlates of binge PuM (decreased mood, increased stress, and anxiety) differ between subjects. It suggests the existence of significant individual differences in binge PuM behaviors, and a need to study these differences, as it may help guide personalized treatment.

Purpose To explore the association between sexual orientation and teen pregnancy (before age 20) in a U.S. nationally representative cohort of young adult females aged 24–32. Methods 5,972 participants in Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health were included. Self-reported sexual orientation identity was categorized as heterosexual, and three sexual minority [SM] groups: mostly heterosexual; bisexual; and lesbian [combining ‘mostly homosexual’ & ‘100% homosexual’]. Stepwise multivariate logistic regression models were fit to compare odds of teen pregnancy, and timing of teen pregnancy, between heterosexual and sexual minority [SM] groups, adjusting for sociodemographic characteristics, sexual victimization history, and sexual risk behaviors. Results After adjusting for sociodemographics and sexual victimization, bisexual women had significantly higher odds than heterosexual peers of teen pregnancy (OR=1.70; 95% CI=1.05, 2.75); this association was marginally significant after adjusting for sexual risk behaviors. Bisexuals were also more likely to have an early (before age 18) teen pregnancy (OR=2.04; 95% CI=1.17, 3.56). In contrast, lesbian women were significantly less likely to have a teen pregnancy than heterosexual (OR=0.47; 95% CI=0.23, 0.97), mostly heterosexual (OR=0.46; 95% CI=0.21, 0.99), and bisexual (OR=0.29; 95% CI=0.12, 0.71) women in final models. Conclusions Expanding upon extant literature, we found opposing risk patterns for teen pregnancy between bisexual and lesbian women, likely due to distinct patterns of sexual risk taking. Findings suggest that SM-inclusive teen pregnancy prevention efforts tailored to meet the unique needs of SM young women, particularly bisexuals, are needed. PMID:27444867

The present investigations applied a theoretical perspective regarding the impact of executive functioning (EF) on sexual risk among substance users, by using a methodological approach designed to examine whether EF subtypes differentially predict behavior patterns. Participants included 104 substance-using HIV-negative gay and bisexual men. Participants completed five neuropsychological assessment tasks selected to tap discrete EF components, and these data were linked to data on substance dependence and behavioral reports of substance use and sexual risk in the past 30 days. Cluster analysis identified three EF subtypes: a) High-performing (good performance across all measures); b) Low Performing (poor performance across all measures); and c) Poor IGT Performance (impairment on the Iowa Gambling Task (IGT) and its variant, but good performance on all other tasks). The three subtypes did not differ in amount of substance use, but the Low-Performing subtype was associated with greater rates of substance dependence. The Low-Performing subtype reported the highest rates of sexual behavior and risk, while the Poor IGT-Performance subtype reported the lowest rates of sexual risk-taking. Global associations between substance use and sexual risk were strongest among the Low-Performing subtype, but event-level associations appeared strongest among individuals in the High-Performing subtype. These data suggest complex associations between EF and sexual risk among substance users, and suggest that the relationship between substance use and sexual risk may vary by EF subtypes.

As an ever-increasing number of people infected with HIV are living longer, healthier lives, concerns about continued transmission are growing along with an awareness of the need to develop "prevention for positives." This study of HIV-positive adults in New York City is the first examination of patterns of sexual behavior in a large, representative cohort of HIV-infected individuals followed over an extended time period. A total of 968 HIV-positive adults were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many persons were not sexually active at all for months at a time; some continued to have multiple partners. Over one third of the cohort had one or more periods when they had engaged in unprotected sex with a partner who was HIV-negative or status unknown (unsafe sex) and one in five reported exchanging sex. Periods of unsafe sex alternated with periods of safer sex. Predictors of sexual risk varied by gender, and among men who had sex with men, and men sexually active with women only. Contextual factors such as partner relations, housing status, and receipt of HIV services were as important as individual attributes as predictors of unsafe sex and sex exchange. The variability observed in sexual risk behavior reported over time provides new insight into the importance of engaging persons living with HIV in ongoing prevention programs.

Thailand has undergone rapid modernization with implications for changes in sexual norms. We investigated sexual behavior and attitudes across generations and gender among a probability sample of the general population of Nonthaburi province located near Bangkok in 2012. A tablet-based survey was performed among 2,138 men and women aged 15-59 years identified through a three-stage, stratified, probability proportional to size, clustered sampling. Descriptive statistical analysis was carried out accounting for the effects of multistage sampling. Relationship of age and gender to sexual behavior and attitudes was analyzed by bivariate analysis followed by multivariate logistic regression analysis to adjust for possible confounding. Patterns of sexual behavior and attitudes varied substantially across generations and gender. We found strong evidence for a decline in the age of sexual initiation, a shift in the type of the first sexual partner, and a greater rate of acceptance of adolescent premarital sex among younger generations. The study highlighted profound changes among young women as evidenced by a higher number of lifetime sexual partners as compared to older women. In contrast to the significant gender gap in older generations, sexual profiles of Thai young women have evolved to resemble those of young men with attitudes gradually converging to similar sexual standards. Our data suggest that higher education, being never-married, and an urban lifestyle may have been associated with these changes. Our study found that Thai sexual norms are changing dramatically. It is vital to continue monitoring such changes, considering the potential impact on the HIV/STIs epidemic and unintended pregnancies.

Receptive anal intercourse has long been recognized as a risk factor for the transmission of HIV and STIs. Most HIV/STI prevention messages continue to emphasize penile-vaginal transmission, so many teens do not recognize anal intercourse as risky sexual behavior. This purpose of this study was to determine the prevalence of anal intercourse, and to describe the relationship between types of sexual relationships (main vs. casual), types of sexual behaviors (vaginal vs. anal sex), and types of contraception used among inner-city sexually experienced adolescents. Reproductive health histories were obtained from 350 sexually experienced adolescent females aged 12-18 years participating in a 5-year STI acquisition study at an urban health center. Baseline sexual behavior data was analyzed and described using frequencies, percentages and chi-square tests. 41% of teens and 86.5% of teens reported engaging in sexual activity with casual and main partners respectively. Sixteen percent of teens with main partners and 12% of those with casual partners engaged in receptive anal intercourse (P = 0.31). Condom use is more prevalent for both vaginal (61% vs. 32.4%, P < or = 0.0001) and anal (47.1% vs. 21.3%, P = 0.0428) intercourse in the context of casual as compared to main sexual relationships. Teens involved in a casual relationship were more likely to use anal intercourse as a form of contraception (41.2% vs. 8.5%, P = 0.0022). It is imperative that health care providers recognize that adolescents engage in anal sex, specifically inquire about their types of sexual behavior and types of sexual relationships so that anticipatory guidance regarding HIV/STI transmission risk reduction education can be tailored to meet their needs.

Sexually transmitted infections are diseases provoking a great social and economic burden as well as health-related problems, and with the aging of society and the extension of life expectancy sexually transmitted infections in the elderly have drawn more attention these days. For the management of sexually transmitted infections in this population, basic epidemiological data need to be established. In this study, 1,804 persons from the general population aged over 60 years visiting health examination centers were tested for syphilis, gonorrhea, and chlamydia, and interviewed about the patterns of sexual behavior of elderly people through questionnaires. The prevalence rates of syphilis, gonorrhea, and chlamydia recorded were 0.222% (4/1804), 0 (none), and 0.776% (14/1804), respectively. The results of the survey showed that the sexual life of the elderly people was currently active, and the sexual behavior of chlamydia patients was distinguished in some characteristics from that of the general participants. Political management to prevent sexually transmitted infections needs to be continued in elderly people as it is in other age groups. More detailed follow-up studies are necessary to determine the incidence and prevalence rates of the diseases in the elderly population in future, and the results of this study are considered to be useful as basic data for such studies.

Sexual risk is an important, oft-neglected area in addiction treatment. This report examines computerized sexual risk assessment and client feedback at intake as means of enhancing counselor awareness of client risk behavior during early treatment, as well as any clinical impact of that counselor awareness. In 2009-2011, new clients at both opiate treatment and drug-free treatment programs endorsed in a computer-assisted assessment at intake 90-day retrospective indices for: being sexually active, having multiple partners, having sex under drug influence, and inconsistently using condoms. Clients were randomly assigned in a 2:1 ratio to receive or not receive a personal feedback report, and those receiving a report chose if a counselor copy was also distributed. Ninety days later, retained clients (N = 79) repeated the assessment and their counselors concurrently reported perceptions of recent client risk behavior. Based on client reports, pretreatment risk behaviors were prevalent among men and women and remained so during treatment. A general linear model revealed greater counselor awareness of subsequent client risk behavior with mutual distribution of intake feedback reports to client and counselor, and at the opiate treatment program. A repeated-measures analysis of variance indicated that counselor awareness did not predict change in temporally stable patterns of sexual risk behavior. CONCLUSIONS/IMPORTANCE: Findings document that computerized intake assessment of sexual risk and mutually distributed feedback reports prompt greater counselor awareness of clients' subsequent risk behavior. Future research is needed to determine how best to prepare counselors to use such awareness to effectively prompt risk reduction in routine care.

Adolescent African-American females are disproportionately impacted by HIV, thus there is a clear need to understand factors associated with increased HIV-risk behaviors among this vulnerable population. We sought to explore the association between a dopamine D4 receptor gene (DRD4), a genetic marker associated with natural variations in rewarding behaviors, and self-reported alcohol-use and sexual risk-behaviors, while controlling for other known correlates of risk-taking such as impulsivity, sensation seeking, and peer norms among a group of high-risk African American female adolescents to evaluate whether this biological factor enhances our understanding of patterns of risk in this vulnerable group.

Abstract Background: the decline in South Africa’s HIV infection rates especially among young women is encouraging. However, studies show that the 15–24-year-old cohort remains vulnerable. As they still report early sexual debut, being involved in sexual partnerships with older men as well as having unprotected sex. These risky sexual behaviors may be linked to factors such as the parent–child sexual health communication and the timing of the first talk. The quality of sexual health information received in school may also be important for enhancing healthier sexual behaviors. Aims and Objectives: to investigate the what, when and how sexual health communication occurs in rural South African families and to determine whether such communication patterns have changed over time. We also wanted to get an in-depth understanding of the roles played by culture, sexual health education and peers in the socialization of young women on sexual matters. Methods: a purposive sample of (n = 55) women who were 18–35 years old was selected and interviewed in focus group discussions (FGDs). Results: the FGD findings show that parent–child communication on sexual matters in rural communities is limited to messages that warn against pregnancy. It is also laden with cultural idioms that are not well explained. The school sexual health curriculum also fails to adequately equip adolescents to make informed decisions regarding sexual matters. All this seems to leave room for reception of misguided information from peers. Conclusions: findings highlight a need for designing interventions that can create awareness for parents on the current developmental needs and sexual behavior of adolescents. For adolescents programs would need to focus on providing skills on personal responsibility, and how to change behavior to enhance sexual health. PMID:29621922

One of the most striking features of the ongoing conflict in the Democratic Republic of Congo (DRC) is the use of sexual violence. In spite of the brutality of these crimes, the experiences of women affected by sexual violence in Eastern DRC remain poorly characterized. This analysis aimed to (1) provide detailed demographics of sexual violence survivors presenting to Panzi Hospital; (2) examine how demographic factors might impact patterns of sexual violence; and (3) describe care-seeking behavior among sexual violence survivors. The demographics and care-seeking behavior of sexual violence survivors in South Kivu Province were described from a retrospective registry-based study of sexual violence survivors presenting to Panzi Hospital (2004-2008). A total of 4311 records were reviewed. The mean age of survivors was 35 years. Most women (53%) were married, self-identified with the Bashi tribe (65%), and reported agriculture as their livelihood (74%). The mean time delay between sexual assault and seeking care was 10.4 months. Five reasons were identified to help explain the lengthy delays to seeking care: waiting for physical symptoms to develop or worsen before seeking medical attention, lack of means to access medical care, concerns that family would find out about the sexual assault, stigma surrounding sexual violence, and being abducted into sexual slavery for prolonged periods of time. Many sexual assault survivors have very delayed presentations to medical attention. Promoting timely access of medical care may best be facilitated by reducing stigma and by educating women about the benefits of early medical care, even in the absence of injuries or symptoms.

Child sexual abuse (CSA) continues to be a significant problem with significant short and long term consequences. However, extant literature is limited by the reliance on retrospective recall of adult samples, single-time assessments, and lack of longitudinal data during the childhood and adolescent years. The purpose of this study was to compare internalizing and externalizing behavior problems of those with a history of sexual abuse to those with a history of maltreatment, but not sexual abuse. We examined whether gender moderated problems over time. Data were drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) at ages 4, 6, 8, 10, 12, 14, and 16 (N=977). The Child Behavior Checklist was used to assess internalizing and externalizing problems. Maltreatment history and types were obtained from official Child Protective Services (CPS) records. Generalized Estimating Equations (GEE) were used to assess behavior problems over time by maltreatment group. Findings indicated significantly more problems in the CSA group than the maltreated group without CSA over time. Internalizing problems were higher for sexually abused boys compared to girls. For sexually abused girls internalizing problems, but not externalizing problems increased with age relative to boys. This pattern was similar among maltreated but not sexually abused youth. Further efforts are needed to examine the psychological effects of maltreatment, particularly CSA longitudinally as well as better understand possible gender differences in order to best guide treatment efforts.

Sexual minorities in the United States are at elevated risk of bullying, discrimination, and violence victimization, all stressors that have been linked to psychological and behavioral stress responses including depressive and anxious symptoms and substance use. Acute and chronic stressors may also elicit physiologic stress responses, including changes in the regulation of the hypothalamic-pituitary-adrenocortical (HPA) axis. Few studies, however, have examined the relationship between minority sexual orientation and diurnal cortisol patterns. The present study included 1670 young adults ages 18-32 years (69% female, 31% male) from the Growing Up Today Study, a prospective cohort of U.S. youth. Participants provided five saliva samples over one day to estimate diurnal cortisol patterns. Sexual orientation groups included: completely heterosexual with no same-sex partners (referent), completely heterosexual with same-sex partners/mostly heterosexual, and gay/lesbian/bisexual. Covariates included perceived stress and stressful life events in the past month. Sex-stratified multilevel models of log-transformed cortisol values were used to model diurnal cortisol patterns, and generalized estimating equations were used to model area under the curve (AUC), both with respect to ground (AUCg) and increase (AUCi). Among females, sexual minorities reported significantly more stressful life events in the past month than their heterosexual counterparts. In adjusted multilevel models, sexual orientation was not significantly associated with diurnal cortisol patterns or with AUCg or AUCi in either females or males. There were no significant interactions between sexual orientation and stressful life events. Time-varying negative mood was significantly associated with higher cortisol levels across the day for both female and male participants, after adjusting for all covariates. This study from a large cohort of U.S. young adults did not detect a relationship between sexual orientation and diurnal cortisol patterns. Despite consistent evidence indicating that, compared to heterosexuals, sexual minorities experience elevated exposure to multiple forms of stressors and adversity across the life course, we did not find differences in diurnal cortisol rhythms by sexual orientation. One possible explanation is that sexual minority participants in the study exhibited physiologic resilience. Copyright © 2016 Elsevier Ltd. All rights reserved.

Background HIV transmission in India is primarily heterosexual and there is a concentrated HIV epidemic among female sex workers (FSWs). Earlier reports demonstrate that many FSWs consume alcohol regularly before sexual encounters. This qualitative study is part of a larger quantitative study designed to assess alcohol consumption patterns among female sex workers and their association with sexual risk taking. Here we investigate the environmental influence, reasons for and consequences of consuming alcohol in the FSW population. Methods Trained staff from two Non-Governmental Organizations in Andhra Pradesh and Kerala conducted semi-structured interviews with 63 FSWs in Chirala, Andhra Pradesh (n=35) and Calicut, Kerala (n=28) following extensive formative research, including social mapping and key informant interviews, to assess drinking patterns and sexual risk behaviors. Results FSWs reported consuming alcohol in multiple contexts: sexual, social, mental health and self-medication. Alcohol consumption during sexual encounters with clients was usually forced, but some women drank voluntarily. Social drinking took place in public locations such as bars and in private locations including deserted buildings, roads and inside autorickshaws (motorcycle taxis). Consequences of alcohol consumption included failure to use condoms and to collect payments from clients, violence, legal problems, gastrointestinal side effects, economic loss and interference with family responsibilities. Conclusion FSWs consume alcohol in multilevel contexts. Alcohol consumption during transactional sex is often forced and can lead to failure to use condoms. Social drinkers consume alcohol with other trusted FSWs for entertainment and to help cope with psychosocial stressors. There are multiple reasons for and consequences of alcohol consumption in this population and future interventions should target each specific aspect of alcohol use. PMID:22608567

2018-01-01

The Juvenile Sex Offender Assessment Protocol-Revised (J-SOAP-II) is the most commonly used measure in the assessment of recidivism risk among juveniles who have committed sexual offenses (JSOs), but mixed support exists for its predictive validity. This study compared the predictive validity of the J-SOAP-II across two offender characteristics, age and sexual drive, in a sample of 156 JSOs who had been discharged from a correctional facility or a residential treatment program. The J-SOAP-II appeared to be a better predictor of sexual recidivism for younger JSOs (14-16 years old) than for older ones (17-19 years old), with significant differences found for the Dynamic Summary Scale and Scale III (Intervention). In addition, several of the measure's scales significantly predicted sexual recidivism for JSOs with a clear pattern of sexualized behavior but not for those without such a pattern, indicating that the J-SOAP-II may have greater clinical utility for JSOs with heightened sexual drive. The implications of these findings are discussed.

In rats, sexual reward, appetitive sexual behaviors and reproduction are modulated by the amount and rate of vaginocervical stimulation. Here the effect of clitoral stimulation (CLS) on proceptivity was assessed. In Exp 1, ovariectomized, hormone-primed Wistar females formed three groups: G1 (1 CLS every second), G2 (1 CLS every 5s) and G3 (no CLS). Precopulatory CLS consisted of 5cycles of 1min of stimulation with the tip of a cotton swab connected to a vibrator device, followed by 1-2min of rest. CLS increased proceptive behavior in G1 compared to G2, but not compared to G3. In Exp 2, gonadally-intact rats in late proestrous received CLS prior to copulation. No differences in sexual behavior were detected between the groups, but CLS enhanced reproduction in females that received >9 intromissions. 28, 66 and 10% of females became pregnant in G1, G2, and G3, respectively. These data indicate that precopulatory CLS affects proceptive behaviors depending on the pattern and rhythm of stimulation in hormone-primed females. In virgin rats that have received sufficient vagino cervical stimulation CLS also increases fertility. Copyright 2010 Elsevier Inc. All rights reserved.

Some quantitative behavioral studies in the USA have concluded that bisexually behaving Latino men are less likely than White men to disclose to their female partners that they have engaged in same-sex risk behavior and/or are HIV-positive, presumably exposing female partners to elevated risk for HIV infection. Nevertheless, very little theoretical or empirical research has been conducted to understand the social factors that promote or inhibit sexual risk disclosure among Latino men who have sex with men (MSM), and much of the existing literature has neglected to contextualize disclosure patterns within broader experiences of stigma and social inequality. This paper examines decisions about disclosure of sex work, same-sex behavior, and sexual risk for HIV among male sex workers in two cities in the Dominican Republic. Data derive from long-term ethnography and qualitative in-depth interviews with 72 male sex workers were used to analyze the relationships among experiences of stigma, social inequality, and patterns of sexual risk disclosure. Thematic analysis of interviews and ethnographic evidence revealed a wide range of stigma management techniques utilized by sex workers to minimize the effects of marginality due to their engagement in homosexuality and sex work. These techniques imposed severe constraints on men’s sexual risk disclosure, and potentially elevated their own and their female partners’ vulnerability to HIV infection. Based on the study’s findings, we conclude that future studies of sexual risk disclosure among ethnic minority MSM should avoid analyzing disclosure as a decontextualized variable, and should seek to examine sexual risk communication as a dynamic social process constrained by hierarchical systems of power and inequality.

This study explored potential variations in childhood sexual abuse (CSA) by examining qualitative accounts of first sexual experiences among non-disclosing, non-gay identified Black men who have sex with men and women (MSMW). We analyzed data from semi-structured qualitative interviews with 33 MSMW who described first sexual experiences with male and female partners. Thematic analysis revealed four patterns of first sexual experiences including: unwanted sexual experiences with a male or female consistent with definitions of childhood sexual abuse; consensual sex with an older male or female; bodily exploration with another male or female child; and consensual sex with a peer-age female. Most of the experiences described by participants as consensual with an older male or female, however, met criteria for childhood sexual abuse found in the extant literature. Several men discussed childhood sexual experiences (CSE) relative to their experiences with alcohol, drugs, and same-sex behavior as adults. Findings suggest that the relationship between CSE and risk-taking behavior may be shaped by whether men perceive their experiences as abusive or consensual, and have implications for researchers, treatment providers and counselors.

Abstract Purpose: Gay and bisexual men (GBM) have poorer health outcomes than the general population. Improved health outcomes will require that GBM have access to healthcare and that healthcare providers are aware of their sexual behaviors. This study sought to examine factors associated with having health insurance and disclosure of same-sex sexual behaviors to primary care providers (PCPs) among GBM in primary same-sex relationships. Methods: We conducted an online survey of a national sample of 722 men in same-sex couples living in the United States. Logistic regression and multinomial regression models were conducted to assess whether characteristic differences existed between men who did and did not have health insurance, and between men who did and did not report that their PCP knew about their same-sex sexual activity. Results: Our national sample of same-sex partnered men identified themselves predominantly as gay and white, and most reported having an income and health insurance. Having health insurance and disclosing sexual behavior to PCPs was associated with increasing age, higher education, and higher income levels. Insurance was less prevalent among nonwhite participants and those living in the south and midwest United States. Disclosure of sexual behavior was more common in urban respondents and in the western United States. In 25% of couples, one partner was insured, while the other was not. Conclusions: Having health insurance and disclosing one's sexual behavior to PCPs was suboptimal overall and occurred in patterns likely to exacerbate health disparities among those GBM already more heavily burdened with poorer health outcomes. These factors need to be considered by PCPs and health policymakers to improve the health of GBM. Patient- and provider-targeted interventions could also improve the health outcomes of GBM.

To assess the seminal characteristics as well as the sexual behavior of men of various age groups to establish the presence of an aging effect on those characteristics. Semen samples were collected from men (n = 792) undergoing in vitro fertilization or intrauterine insemination in cases of female factor infertility only. Samples were collected using a seminal collection device at intercourse and evaluated manually according to World Health Organization (WHO) standards. Men were divided into four groups according to their ages: (i) 20-30, (ii) 31-40, (iii) 41-50 and (iv) 51-60 years, and their seminal characteristics and responses to a sexual behavior questionnaire were compared. The data showed statistically significant differences in the seminal characteristics tested, most notably in the sperm concentration, motility, grade of motility, hypo-osmotic swelling and normal sperm morphology. Furthermore, the decline in normal sperm morphology with age was more pronounced when using strict criteria rather than WHO standards. There were also differences in total sperm count, total motile sperm and total functional sperm fraction (assessed by both WHO and strict criteria). Significant differences were also observed in the sexual behavior patterns in older men in terms of the number of years they have been trying to conceive, sexual frequency and sexual satisfaction. The data clearly illustrate an aging effect on semen characteristics and sexual behavior in men as they age. It is suggested that the aging effect be taken into consideration when proposing normal standard values for semen characteristics in routine semen analysis as outlined by WHO standards.

Sexual size dimorphism, canine dimorphism, and male-male competition in primates: where do humans fit in?

PubMed

Plavcan, J Michael

2012-03-01

Sexual size dimorphism is generally associated with sexual selection via agonistic male competition in nonhuman primates. These primate models play an important role in understanding the origins and evolution of human behavior. Human size dimorphism is often hypothesized to be associated with high rates of male violence and polygyny. This raises the question of whether human dimorphism and patterns of male violence are inherited from a common ancestor with chimpanzees or are uniquely derived. Here I review patterns of, and causal models for, dimorphism in humans and other primates. While dimorphism in primates is associated with agonistic male mate competition, a variety of factors can affect male and female size, and thereby dimorphism. The causes of human sexual size dimorphism are uncertain, and could involve several non-mutually-exclusive mechanisms, such as mate competition, resource competition, intergroup violence, and female choice. A phylogenetic reconstruction of the evolution of dimorphism, including fossil hominins, indicates that the modern human condition is derived. This suggests that at least some behavioral similarities with Pan associated with dimorphism may have arisen independently, and not directly from a common ancestor.

To describe the pattern of drug use among men who have sex with men (MSM) living in Spain and its association with sexual risk practices. The European MSM Internet Survey was implemented in 2010 in 38 European countries on websites for MSM and collected data on sociodemographics, sexual behavior, and other sexual health variables. The association between unprotected anal intercourse (UAI) with casual partners and drug consumption was evaluated using multivariate logistic regression models. Among the 13,111 participants, most consumed drugs were cannabis (30.1%), popper (28.4%) and cocaine (18.7%). The risk of UAI with casual partners was 1.5 among those who had used drugs in relation to the other participants. The proportion of MSM who had injected drugs at least once in life was 2.5%, and 1.4% in the last 12 months. The prevalence of UAI with casual partners (53.4%), human immunodeficiency virus (HIV) (23%), hepatitis C (8.2%) and sexually transmitted infections (STI) (15.8%) was higher in MSM injectors related to those who had not used injected drugs (P<.05). The results of this study confirm a high prevalence of drug use in MSM and their relationship to sexual risk behavior. Although the use of injected drugs in MSM is a minority, this group reported a higher level of sexual risk behaviors, self-reported HIV, hepatitis C and other STI.

Young people in the Middle East and North Africa (MENA) are profoundly affected by violence, high unemployment, and economic hardship. Experiences of community-level violence and personal trauma increase the likelihood that young people will engage in risky behaviors that include smoking, drug use, and unsafe sex. Little is known about the sexual behavior of young people in the region, particularly in the occupied Palestinian territory (oPt). Our aim in this study was to gain an insight into the perceived prevalence and patterns of sexual behavior among Palestinian youth. The study was based on ten focus groups and 17 in-depth interviews with young people aged 16-24 years as part of the formative phase of a cross-sectional representative study of risk behaviors in the West Bank, including Jerusalem, in 2012. The sample was selected using a combination of purposive and convenience sampling. Qualitative analysis was used to code detailed notes of focus groups and interviews. Based on participants' reports, different types of sexual activity outside marriage were not uncommon, even in conservative communities. The most reported sexual activity was non-penetrative sex: oral and anal intercourse, and virtual sex. Some young people had sexual intercourse with sex workers; they went to brothels in Israel and to brothels operating clandestinely in the West Bank, including East Jerusalem. Most respondents were of the opinion that young people did not usually use protection during sexual intercourse. Many reported that youth engage in different types of sexual activity outside marriage for several reasons: to challenge the culture, financial constraints and inability to marry, basic human need, personal pleasure, suppression, to kill boredom, and to prove manhood. In contrast with the conservative social context of the occupied Palestinian territory (oPt), the findings suggest that sexual activities outside marriage may be more common than is currently assumed. Sexual behavior in the oPt is a concern because of the low awareness of the potential health consequences. The results draw attention to the need to incorporate sexual reproductive health into the national agenda and ensure that it is included in the programs of national institutions.

Parallel bodies of research have described the diverse and complex ways that men understand and construct their masculine identities (often termed“masculinities”) and, separately, how adherence to traditional notions of masculinity places men at risk for negative sexual and health outcomes. The goal of this analysis was to bring together these two streams of inquiry. Using data from a national, online sample of 555 hetero-sexually active young men, we employed latent class analysis (LCA) to detect patterns of masculine identities based on men’s endorsement of behavioral and attitudinal indicators of“dominant” masculinity, including sexual attitudes and behaviors. LCA identified four conceptually distinct masculine identity profiles. Twogroups, termed the Normative and Normative/Male Activities groups, respectively, constituted 88 % of the sample and were characterized by low levels of adherence to attitudes, sexual scripts, and behaviors consistent with“dominant”masculinity, but differed in their levels of engagement in male-oriented activities (e.g., sports teams). Only eight percent of the sample comprised a masculinity profile consistent with “traditional” ideas about masculinity; this group was labeled Misogynistic because of high levels of sexual assault and violence toward female partners. The remaining four percent constituted a Sex-Focused group, characterized by high numbers of sexual partners, but relatively low endorsement of other indicators of traditional masculinity. Follow-up analyses showed a small number of differences across groups on sexual and substance use health indicators. Findings have implications for sexual and behavioral health interventions and suggest that very few young men embody or endorse rigidly traditional forms of masculinity. PMID:26496914

Relative growth, ontogeny, and sexual dimorphism in gorilla (Gorilla gorilla gorilla and G. g. beringei): evolutionary and ecological considerations.

PubMed

Taylor, A B

1997-01-01

Gorillas are the largest and among the most sexually dimorphic of all extant primates. While gorillas have been incorporated in broad-level comparisons among large-bodied hominoids or in studies of the African apes, comparisons between gorilla subspecies have been rare. During the past decade, however, behavioral, morphological, and molecular data from a number of studies have indicated that the western lowland (Gorilla gorilla gorilla) and eastern mountain (Gorilla gorilla beringei) subspecies differ to a greater extent than has been previously believed. In this study I compare patterns of relative growth of the postcranial skeleton to evaluate whether differences between subspecies result from the differential extension of common patterns of relative growth. In addition, patterns of ontogeny and sexual dimorphism are also examined. Linear skeletal dimensions and skeletal weight were obtained for ontogenetic series of male and female G.g. gorilla (n = 315) and G.g. beringei (n = 38). Bivariate and multivariate methods of analysis were used to test for differences in patterns of relative growth, ontogeny, and sexual dimorphism between sexes of each subspecies and in same-sex comparisons between subspecies. Results indicate males and females of both subspecies are ontogenetically scaled for postcranial proportions and that females undergo an earlier skeletal growth spurt compared to males. However, results also indicate that the onset of the female growth spurt occurs at different dental stages in lowland and mountain gorillas and that mountain gorillas may be characterized by higher rates of growth. Finally, data demonstrate lowland and mountain gorilla females do not differ significantly in adult body size, but mountain gorilla males are significantly larger than lowland gorilla males, suggesting mountain gorillas are characterized by a higher degree of sexual dimorphism in body size. Thus, although lowland and mountain gorillas do not appear to have evolved novel adaptations of the postcranium which correlate with differences in locomotor behavior, the present investigation establishes subspecies differences in ontogeny and sexual dimorphism which may be linked with ecological variation. Specifically, these findings are evaluated in the context of risk aversion models which predict higher growth rates and increased levels of sexual dimorphism in extreme folivores.

Understanding current practices of lubricant use during anal intercourse can help to assess the contexts for the introduction of topical rectal microbicides as an HIV prevention tool for men who have sex with men (MSM). We used quantitative and qualitative methods to assess: current patterns of lubricant use; preferred characteristics of commercial lubricant formulations; and social and behavioral contexts of lubricant use within male sexual partnerships in Lima, Peru. Between 2007 and 2008, we conducted a quantitative behavioral survey with 547 MSM followed by qualitative individual and group interviews with 36 MSM from Lima, Peru. Approximately half of all participants in the quantitative survey (50.3%) reported using commercial lubricant during intercourse occasionally or consistently during the preceding two months, with lack of availability at the time of intercourse the most commonly reported reason for non-use. No clear preferences regarding the color, smell, taste, or viscosity of commercial lubricants were identified, and all participants who reported using a commercial lubricant used the same product (“Love-Lub”). In the qualitative analysis, participants characterized lubricant use as a sexual practice consistently controlled by the receptive partner, who typically obtained and applied lubricant independently, with or without the consent of the insertive partner. Quantitative findings supported this differential pattern of lubricant use, with men who reported sexual identities or roles consistent with receptive anal intercourse, including unprotected receptive intercourse, more likely to report lubricant use than MSM who claimed an exclusively insertive sexual role. Given the social, behavioral, and biological factors contributing to increased vulnerability for HIV and STI acquisition by the receptive partner in anal intercourse, delivery of a topical rectal microbicide as a lubricant formulation could provide an important HIV prevention resource for at-risk MSM in Lima, Peru.

Traditional views of sexual behaviors are frequently changing as the factors influencing them are changing. Therefore, assessing sexual practices that are not part of the tradition would be necessary. The objective of this study was to identify the types of sexual practices, their development pattern and how these development patterns expose students to sexually transmitted infections and unplanned pregnancy. A cross-sectional survey was conducted on a sample of 1986 (1612 males, 365 females, and with 9 subjects' gender not indicated) Jimma university students in August 2009 with their age ranging from 17-45 years (median = 20). Quantitative data was collected using a piloted, precoded questionnaire and qualitative data was collected from six focus group discussions. Logistic regression and descriptive statistics were computed and qualitative findings were triangulated with quantitative findings. P-value less than 0.05 was considered significant. Practice of penile to vaginal intercourse, masturbation, kissing, oral sex, and anal sex were reported by 567 (28.9%), 688 (36.7%), 840 (42.4%), 179 (9.2%) and 83 (4.3%) of the respondents, respectively. Respondents had two years (one year with and one year without condom) of sexual experience before marriage. Sixty percent of those who had sexual experience were exposed to sexually transmitted infections and 46.6% were exposed to both unplanned pregnancy and sexually transmitted infections. Forty seven percent of those who practiced oral sex and 29% of those who practiced anal sex did not consider their acts as sexual intercourse. University students are high risk groups that need more focused research and concerted health care. The term 'sexual intercourse' should be consciously defined for its future use in Ethiopia. Furthermore, Service providers and researchers should address all types of sexual practices.

Background Behavioral interventions based on the Protection Motivation Theory (PMT) have been demonstrated to reduce HIV risk behavior among mid- and older adolescents in different settings across the globe but have not been evaluated among Caribbean nations and have received limited evaluation among pre-adolescents. Objective To determine 1) the effectiveness among pre-adolescents in The Bahamas of a PMT-based HIV prevention program “Focus on Youth in the Caribbean” (FOYC) and 2) the role of the targeted PMT constructs in intervention effect. Methods 1,360 sixth grade youth (10-11 years of age) from 15 urban schools in New Providence, The Bahamas were randomized by school to receive either FOYC or a control condition. Data collected at baseline, six and 12 months post intervention were analyzed. A five-step scheme was used to assess sexual behavior progression, ranging from “1” = “a virgin without intention to have sex” to” 5″ = “having sex without a condom”. Group-based trajectory analysis was utilized in assessing the program effect. Results Two sexual behavior progression patterns were detected: slow progressors and quick progressors. Receiving FOYC reduced the likelihood for adolescents to become quick progressors (adjusted OR = 0.77, 95% CI: 0.64-1.00). The observed effectiveness was especially impacted by a subset of the targeted PMT constructs. Conclusion FOYC effectively delays sexual risk among Bahamian pre-adolescents. The group-based trajectory analysis provides an analytical approach for assessing interventions among adolescents with low rates and diverse progression patterns of sexual activity. PMID:19116781

This study aims to document the prevalence of repeated patterns of dating victimization and to examine, within the frameworks of an ecological model and lifestyle/routine activities theories, associations between such patterns and family, peer, and individual factors. Dating victimization in adolescence (age 15) and early adulthood (age 21) was evaluated in 443 female participants. Multinomial logistic regression analyses revealed that history of family violence, childhood behavior problems, and adolescent high-risk behaviors were associated with an increased risk for girls of being victimized (psychologically and/or physically/sexually) in their dating relationships, either in adolescence or early adulthood, or at both developmental periods. © The Author(s) 2015.

The impact of adolescent risk behavior on partner relationships

2015-01-01

Prior literature suggests that involvement in adolescent risk behaviors will have short- and long-term consequences that disrupt the orderly flow of later development, including impacts on patterns of partner relationships. In this study, we explore how adolescent involvement in delinquency, drug use, and sexual behavior at an early age affects the likelihood and timing of both marriage and cohabitation using a sample from the Rochester Youth Development Study. We also examine the direct effects of dropping out of high school, teenage parenthood, and financial stress during emerging adulthood as well as their potential role as mediators of the relationships between adolescent risk behaviors and partnering for both males and females. Overall, there is not very strong support for a direct relationship between adolescent delinquency, drug use, or early sexual behavior and patterns of partner formation. In contrast, the more proximal relationships, indicated by precocious transitions to adulthood and financial instability, are more consistently related to partner formation. These findings support models of cumulative disadvantage: early adolescent problem behaviors are weakly related to partner formation, but appear to set in motion cascading consequences that influence the transition to adulthood and, in turn, these more proximal variables are more consistently related to partner formation.

CONTEXT Studies have shown that obesity is associated with increased sexual risk-taking, particularly among adolescent females, but the relationships between obesity, perceived weight and sexual risk behaviors are poorly understood. METHODS Integrative data analysis was performed that combined baseline data from the 1994–1995 National Longitudinal Study of Adolescent Health (from 17,606 respondents in grades 7–12) and the 1997 National Longitudinal Survey of Youth (from 7,752 respondents aged 12–16). Using six sexual behaviors measured in both data sets (age at first intercourse, various measures of contraceptive use and number of partners), cluster analysis was conducted that identified five distinct behavior clusters. Multivariate ordinal logistic regression analysis examined associations between adolescents’ weight status (categorized as underweight, normal-weight, overweight or obese) and weight perception and their cluster membership. RESULTS Among males, being underweight, rather than normal-weight, was negatively associated with membership in increasingly risky clusters (odds ratio, 0.5), as was the perception of being overweight, as opposed to about the right weight (0.8). However, being overweight was positively associated with males’ membership in increasingly risky clusters (1.3). Among females, being obese, rather than normal-weight, was negatively correlated with membership in increasingly risky clusters (0.8), while the perception of being overweight was positively correlated with such membership (1.1). CONCLUSIONS Both objective and subjective assessments of weight are associated with the clustering of risky sexual behaviors among adolescents, and these behavioral patterns differ by gender.

The effects of prior workplace behavior on subsequent sexual harassment judgments.

Wiener, Richard L; Winter, Ryan; Rogers, Melanie; Arnot, Lucy

2004-02-01

A dual processing model of sexual harassment judgments predicted that the behavior of a complainant in a prior case would influence evaluations in an unrelated subsequent case. In the first of two experimental scenarios depicting social-sexual conduct at work, the female complainant's conduct was manipulated to be aggressive, submissive, ambiguous, or neutral. Half of the participants were asked to reflect upon the first scenario after reading it and before answering responsibility questions. The other half simply reviewed the scenario and answered the questions. When the complainant acted aggressively, her behavior in the first scenario caused men who reflected on the fact pattern to find less evidence of harassment. Most interestingly, an aggressive complainant observed in the first scenario caused participants (especially women) to rate lower the likelihood that a neutral complainant in a second independent case was the victim of gender discrimination. Across cases, men found less evidence of harassment than did women.

Sexual selection modulates genetic conflicts and patterns of genomic imprinting.

Recent years have seen a surge of interest in linking the theories of kin selection and sexual selection. In particular, there is a growing appreciation that kin selection, arising through demographic factors such as sex-biased dispersal, may modulate sexual conflicts, including in the context of male-female arms races characterized by coevolutionary cycles. However, evolutionary conflicts of interest need not only occur between individuals, but may also occur within individuals, and sex-specific demography is known to foment such intragenomic conflict in relation to social behavior. Whether and how this logic holds in the context of sexual conflict-and, in particular, in relation to coevolutionary cycles-remains obscure. We develop a kin-selection model to investigate the interests of different genes involved in sexual and intragenomic conflict, and we show that consideration of these conflicting interests yields novel predictions concerning parent-of-origin specific patterns of gene expression and the detrimental effects of different classes of mutation and epimutation at loci underpinning sexually selected phenotypes. © 2016 The Author(s).

Personality as a predictor of unprotected sexual behavior among people living with HIV/AIDS: a systematic review.

PubMed

Shuper, Paul A; Joharchi, Narges; Rehm, Jürgen

2014-02-01

The present investigation involved a systematic literature review to (1) identify associations between personality constructs and unprotected sex among people living with HIV/AIDS (PLWH); (2) assess patterns of direct versus indirect personality-risky sex associations; and (3) explore possible differences in personality-risky sex associations among PLWH versus non-infected populations. Among the 26 studies yielded through the systematic search, sensation seeking and sexual compulsivity were the constructs most frequently examined, with fewer studies investigating traditional personality typologies. Personality constructs that were more conceptually proximal to the sexual act, such as sexual compulsivity and sex-related sub-components of sensation seeking, showed relatively direct associations with unprotected sex, whereas more conceptually distal constructs such as generalized impulsivity demonstrated only weak or indirect associations. Associations were also frequently mediated by other risk factors, including perceived responsibility and substance use. These findings have implications for the development of interventions to reduce high risk sexual behavior among PLWH.

To elucidate patient language that supports changing a health behavior (change talk) or sustaining the behavior (sustain talk). We developed a novel coding system to characterize topics of patient speech in a motivational intervention targeting alcohol and HIV/sexual risk in 90 Emergency Department patients. We further coded patient language as change or sustain talk. For both alcohol and sex, discussions focusing on benefits of behavior change or change planning were most likely to involve change talk, and these topics comprised a large portion of all change talk. Greater discussion of barriers and facilitators of change also was associated with more change talk. For alcohol use, benefits of drinking behavior was the most common topic of sustain talk. For sex risk, benefits of sexual behavior were rarely discussed, and sustain talk centered more on patterns and contexts, negations of drawbacks, and drawbacks of sexual risk behavior change. Topic coding provided unique insights into the content of patient change and sustain talk. Patients are most likely to voice change talk when conversation focuses on behavior change rather than ongoing behavior. Interventions addressing multiple health behaviors should address the unique motivations for maintaining specific risky behaviors. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Social context of human immunodeficiency virus transmission in Africa: historical and cultural bases of east and central African sexual relations.

Larson, A

The literature relating to the social context of sexual relations in East and Central Africa has several implications for the heterosexual transmission of human immunodeficiency virus (HIV). Colonially created cities in the region still discriminate economically and socially against women. Rapid urbanization is occurring, but migrants maintain strong ties with rural areas. Traditional attitudes towards marriage and sexuality affect urban behavior in the extent of marital stability, the frequency of polygyny, and the emotional bond between spouses. Ethnic groups in Kampala and Nairobi exemplify the cultural foundations of two forms of sexual relations found in the region, one characterized by prostitution and the other by small circles of interchanging lovers. The first results in a more rapid spread of HIV through the urban population and outwards into rural areas. Each pattern exerts unique constraints on behavioral change and requires different prevention campaigns.

This study compares sexual risk behaviors among male and female migrant market vendors in Almaty, Kazakhstan. From the Barakholka Market, 209 male and 213 female market vendors were randomly recruited. Self-reported data were collected through standardized face-to-face interviews. Dry blood spot was used as specimen for syphilis testing. Propensity score stratification was used to estimate adjusted prevalence or rate ratios by gender. Compared to male migrant workers, females had lower HIV knowledge and were less likely to have multiple sexual partners. There was no evidence of a gender difference for prevalence of syphilis, condom use with unsteady partners, and safe sex communication between couples. Associations between mobility patterns and engagement in multiple sexual partnerships were stronger among women than men. Efforts should be made to mitigate the gender differential in HIV knowledge among migrants, especially women. Such efforts need to be implemented in both home and host countries.

Effect of changes in human ecology and behavior on patterns of sexually transmitted diseases, including human immunodeficiency virus infection.

Wasserheit, J N

The last 20 years have witnessed six striking changes in patterns of sexually transmitted diseases (STDs): emergence of new STD organisms and etiologies, reemergence of old STDs, shifts in the populations in which STDs are concentrated, shifts in the etiological spectra of STD syndromes, alterations in the incidence of STD complications, and increases in antimicrobial resistance. For example, human immunodeficiency virus (HIV) emerged to devastate the United States with a fatal pandemic involving at least 1 million people. The incidence of syphilis rose progressively after 1956 to reach a 40-year peak by 1990. In both cases, disease patterns shifted from homosexual men to include minority heterosexuals. Over the last decade, gonorrhea became increasingly concentrated among adolescents, and several new types of antimicrobial resistance appeared. Three interrelated types of environments affect STD patterns. The microbiologic, hormonal, and immunologic microenvironments most directly influence susceptibility, infectiousness, and development of sequelae. These microenvironments are shaped, in part, by the personal environments created by an individual's sexual, substance-use, and health-related behaviors. The personal environments are also important determinants of acquisition of infection and development of sequelae but, in addition, they mediate risk of exposure to infection. These are, therefore, the environments that most directly affect changing disease patterns. Finally, individuals' personal environments are, in turn, molded by powerful macroenvironmental forces, including socioeconomic, demographic, geographic, political, epidemiologic, and technological factors. Over the past 20 years, the profound changes that have occurred in many aspects of the personal environment and the macroenvironment have been reflected in new STD patterns. PMID:8146135

Objectives. We assessed disparities in weight and weight-related behaviors among college students by sexual orientation and gender. Methods. We performed cross-sectional analyses of pooled annual data (2007–2011; n = 33 907) from students participating in a Minnesota state-based survey of 40 two- and four-year colleges and universities. Sexual orientation included heterosexual, gay or lesbian, bisexual, unsure, and discordant heterosexual (heterosexuals engaging in same-sex sexual experiences). Dependent variables included weight status (derived from self-reported weight and height), diet (fruits, vegetables, soda, fast food, restaurant meals, breakfast), physical activity, screen time, unhealthy weight control, and body satisfaction. Results. Bisexual and lesbian women were more likely to be obese than heterosexual and discordant heterosexual women. Bisexual women were at high risk for unhealthy weight, diet, physical activity, and weight control behaviors. Gay and bisexual men exhibited poor activity patterns, though gay men consumed significantly less regular soda (and significantly more diet soda) than heterosexual men. Conclusions. We observed disparities in weight-, diet-, and physical activity–related factors across sexual orientation among college youths. Additional research is needed to better understand these disparities and the most appropriate intervention strategies to address them. PMID:25393177

Copulation with intromission or manual vaginocervical stimulation (VCS) shortens the duration that intact female rats maintain lordosis responding during estrus. The present study examined whether VCS could shorten the duration of both appetitive and consummatory measures of female sexual behavior, and whether these effects occur differentially in time and across different hormone priming intervals. Ovariectomized, sexually experienced female rats were administered subcutaneous injections of estradiol benzoate 48 h and progesterone 4 h, before receiving 50 manual VCSs with a lubricated glass rod distributed over 1 h. Control females received sham VCSs distributed over the same time. The females were then tested for sexual behavior in bilevel chambers with two sexually vigorous males (to one ejaculatory series or 10 min with each male, separated by 5 min) 12, 16, and 20 h after VCS. Prior to the final hormone treatment, different groups of females had been given the same hormone treatment either 28, 14, 7, or 4 days before. In females tested at 28- and 14-day hormone intervals, VCS induced both active and passive rejection responses at 12, 16, and 20 h. In contrast, females that received sham VCS displayed relatively normal sexual behavior at 12 h, although by 16 and 20 h these females displayed active and passive rejection. Females tested at 7- or 4-day intervals displayed normal levels of lordosis at all testing times, regardless of VCS treatment. These data indicate that VCS facilitates rejection responses that precede the decrease in lordosis responsiveness. However, the effects of VCS are dependent on the frequency of hormone priming, suggesting that hormone treatment may block some of the long-term inhibitory effects of VCS on female sexual behavior.

The repeated pattern of heavy intoxication followed by withdrawal from alcohol (i.e., "binge drinking") has been found to have substantial adverse effects on prefrontal neural systems associated with decision-making and impulse control. Repeated binge drinking has been linked to risky and unplanned sexual behavior; however few studies have examined the role of impulsivity and related cognitive processes in understanding this association. The aim of this study was to examine the relationship between binge drinking, "reflection impulsivity" (deficits in gathering and evaluating information during decision-making), alcohol-related expectancies, and unplanned sexual behavior in a sample of young social drinkers. Ninety-two university students completed the alcohol use questionnaire (AUQ) to measure alcohol intake and binge drinking. Two groups (low-binge and high-binge) were generated from the AUQ data. The Information Sampling Task (IST) was used to measure reflection impulsivity; the Alcohol Expectancy Questionnaire (AEQ) for alcohol outcome expectancies; and an unplanned sexual behavior questionnaire, which asked about the number of unplanned sexual events. When compared to the low-binge drinking group, the high-binge drinkers had significantly more unplanned sexual encounters and were impaired on the IST, reflection-impulsivity task. They scored higher on the alcohol expectancy factors of sociability, risk and aggression, negative self-perception, and in particular liquid courage. In a regression analysis, number of unplanned sexual encounters, binge drinking score, and liquid courage were all significantly related. These results support the role of binge drinking in reduced impulse control and decision-making deficits. The findings indicate that high-binge drinkers demonstrate impairments on an impulse control task similar to that observed in dependent samples and this may be a factor in understanding the negative behavioral consequences associated with excessive alcohol use.

Potential contribution of progesterone receptors to the development of sexual behavior in male and female mice.

We previously showed that estradiol can have both defeminizing and feminizing effects on the developing mouse brain. Pre- and early postnatal estradiol defeminized the ability to show lordosis in adulthood, whereas prepubertal estradiol feminized this ability. Furthermore, we found that estradiol upregulates progesterone receptors (PR) during development, inducing both a male-and female-typical pattern of PR expression in the mouse hypothalamus. In the present study, we took advantage of a newly developed PR antagonist (ZK 137316) to determine whether PR contributes to either male- or female-typical sexual differentiation. Thus groups of male and female C57Bl/6j mice were treated with ZK 137316 or OIL as control: males were treated neonatally (P0-P10), during the critical period for male sexual differentiation, and females were treated prepubertally (P15-P25), during the critical period for female sexual differentiation. In adulthood, mice were tested for sexual behavior. In males, some minor effects of neonatal ZK treatment on sexual behavior were observed: latencies to the first mount, intromission and ejaculation were decreased in neonatally ZK treated males; however, this effect disappeared by the second mating test. By contrast, female mice treated with ZK during the prepubertal period showed significantly less lordosis than OIL-treated females. Mate preferences were not affected in either males or females treated with ZK during development. Taken together, these results suggest a role for PR and thus perhaps progesterone in the development of lordosis behavior in female mice. By contrast, no obvious role for PR can be discerned in the development of male sexual behavior. Copyright © 2016 Elsevier Inc. All rights reserved.

Peruvian men who have sex with men (MSM) and transgender women (TGW) experience the double burden of a highly concentrated HIV epidemic with a high prevalence of alcohol use disorders (AUDs). Recent research has associated both with risky sexual behaviors, including unprotected sex, having multiple sexual partners, engaging in sex work, having recent sexually transmitted infections, and having HIV-infected partners. AUDs have also been associated in MSM/TGW with being unaware of HIV+ status. This study aims to further examine issues associated with alcohol consumption, HIV infection, and risk behaviors in a qualitative analysis of focus groups conducted with MSM/TGW in Peru. A total of 26 MSM/TGW participants with AUDs participated in three semi-structured focus groups in Lima, Peru. Content analysis was facilitated by software, and specific themes were elucidated. Participants described their drinking patterns, including the types of alcoholic drinks they consumed. They depicted drinking frequently and over multiple-day sessions. Problematic drinking behaviors were described, as well as the perceived characteristics of alcohol dependence. Interestingly, HIV-infected participants who were prescribed antiretroviral therapy did not believe that their drinking affected their medication adherence. These insights can aid in the design of future interventions aiming to reduce problematic drinking as well as HIV-related risk behaviors and, subsequently, HIV incidence. Peruvian MSM/TGW exhibit problematic drinking, which may be associated with risky sexual behaviors and HIV transmission. Interest in reducing alcohol consumption was high, suggesting the need for targeted behavioral and pharmacological interventions.

Few studies have examined the context of a wide range of risk behaviors among emerging adults (ages 18-25 years), approximately half of whom in the USA enroll in post-secondary educational institutions. The objective of this research was to examine behavioral patterning in weight behaviors (diet and physical activity), substance use, sexual behavior, stress, and sleep among undergraduate students. Health survey data were collected among undergraduates attending a large, public US university (n = 2,026). Latent class analysis was used to identify homogeneous, mutually exclusive "classes" (patterns) of ten leading risk behaviors. Resulting classes differed for males and females. Female classes were defined as: (1) poor lifestyle (diet, physical activity, sleep), yet low-risk behaviors (e.g., smoking, binge drinking, sexual risk, drunk driving; 40.0% of females), (2) high risk (high substance use, intoxicated sex, drunk driving, poor diet, inadequate sleep) (24.3%), (3) moderate lifestyle, few risk behaviors (20.4%), (4) "health conscious" (favorable diet/physical activity with some unhealthy weight control; 15.4%). Male classes were: (1) poor lifestyle, low risk (with notably high stress, insufficient sleep, 9.2% of males), (2) high risk (33.6% of males, similar to class 2 in females), (3) moderate lifestyle, low risk (51.0%), and (4) "classic jocks" (high physical activity, binge drinking, 6.2%). To our knowledge, this is among the first research to examine complex lifestyle patterning among college youth, particularly with emphasis on the role of weight-related behaviors. These findings have important implications for targeting much needed health promotion strategies among emerging adults and college youth.

The evolutionary ecology of the Lygaeidae

The Lygaeidae (sensu lato) are a highly successful family of true bugs found worldwide, yet many aspects of their ecology and evolution remain obscure or unknown. While a few species have attracted considerable attention as model species for the study of insect physiology, it is only relatively recently that biologists have begun to explore aspects of their behavior, life history evolution, and patterns of intra- and interspecific ecological interactions across more species. As a result though, a range of new phenotypes and opportunities for addressing current questions in evolutionary ecology has been uncovered. For example, researchers have revealed hitherto unexpectedly rich patterns of bacterial symbiosis, begun to explore the evolutionary function of the family's complex genitalia, and also found evidence of parthenogenesis. Here we review our current understanding of the biology and ecology of the group as a whole, focusing on several of the best-studied characteristics of the group, including aposematism (i.e., the evolution of warning coloration), chemical communication, sexual selection (especially, postcopulatory sexual selection), sexual conflict, and patterns of host-endosymbiont coevolution. Importantly, many of these aspects of lygaeid biology are likely to interact, offering new avenues for research, for instance into how the evolution of aposematism influences sexual selection. With the growing availability of genomic tools for previously “non-model” organisms, combined with the relative ease of keeping many of the polyphagous species in the laboratory, we argue that these bugs offer many opportunities for behavioral and evolutionary ecologists.

Sexual conflict between parents: offspring desertion and asymmetrical parental care.

PubMed

Székely, Tamás

2014-09-25

Parental care is an immensely variable social behavior, and sexual conflict offers a powerful paradigm to understand this diversity. Conflict over care (usually considered as a type of postzygotic sexual conflict) is common, because the evolutionary interests of male and female parents are rarely identical. I investigate how sexual conflict over care may facilitate the emergence and maintenance of diverse parenting strategies and argue that researchers should combine two fundamental concepts in social behavior to understand care patterns: cooperation and conflict. Behavioral evidence of conflict over care is well established, studies have estimated specific fitness implications of conflict for males or females, and experiments have investigated specific components of conflict. However, studies are long overdue to reveal the full implications of conflict for both males and females. Manipulating (or harming) the opposite sex seems less common in postzygotic conflicts than in prezygotic conflicts because by manipulating, coercing, or harming the opposite sex, the reproductive interest of the actor is also reduced. Parental care is a complex trait, although few studies have yet considered the implications of multidimensionality for parental conflict. Future research in parental conflict will benefit from understanding the behavioral interactions between male and female parents (e.g., negotiation, learning, and coercion), the genetic and neurogenomic bases of parental behavior, and the influence of social environment on parental strategies. Empirical studies are needed to put sexual conflict in a population context and reveal feedback between mate choice, pair bonds and parenting strategies, and their demographic consequences for the population such as mortalities and sex ratios. Taken together, sexual conflict offers a fascinating avenue for understanding the causes and consequences of parenting behavior, sex roles, and breeding system evolution.

Accurate information and knowledge about cervical cancer and screening importantly influence women's cervical screening participation. Sexual behavior plays a crucial role in human papillomavirus transmission and the subsequent development of cervical cancer. Indeed, the uptake of cervical screening among Chinese women is relatively low compared with other populations. To understand women's attendance pattern of cervical screening, knowledge about cervical cancer and screening, and factors influencing their utilization of cervical screening in mainland China. A cross-sectional survey was conducted to collect women's participation pattern for cervical screening, knowledge about cervical cancer and screening, sociodemographic information and sexual history, and barriers to participating in cervical screening. Married women and women who had had their first intercourse after the age of 21 years were significantly more likely to participate in screening. Screened women demonstrated a higher level of knowledge about the cervical screening procedure compared with nonscreened women (P = .002). Also, the scores of individual items such as women's knowledge of cervical screening and risk factors were significantly different between the 2 groups. The current system of free physical examinations for women in mainland China is a major motivator for women's utilization of cervical screening services. Chinese women's marital status and sexual history influence their screening behavior. Unmarried women who have ever had sex should be encouraged to have cervical screening, and consistent and appropriate information about the preventive nature of cervical screening and risk factors associated with cervical cancer should be provided to the general public.

Has dopamine a physiological role in the control of sexual behavior? A critical review of the evidence.

PubMed

Paredes, Raúl G; Agmo, Anders

2004-06-01

The role of dopaminergic systems in the control of sexual behavior has been a subject of study for at least 40 years. Not surprisingly, reviews of the area have been published at variable intervals. However, the earlier reviews have been summaries of published research rather than a critical analysis of it. They have focused upon the conclusions presented in the original research papers rather than on evaluating the reliability and functional significance of the data reported to support these conclusions. During the last few years, important new knowledge concerning dopaminergic systems and their behavioral functions as well as the possible role of these systems in sexual behavior has been obtained. For the first time, it is now possible to integrate the data obtained in studies of sexual behavior into the wider context of general dopaminergic functions. To make this possible, we first present an analysis of the nature and organization of sexual behavior followed by a summary of current knowledge about the brain structures of crucial importance for this behavior. We then proceed with a description of the dopaminergic systems within or projecting to these structures. Whenever possible, we also try to include data on the electrophysiological actions of dopamine. Thereafter, we proceed with analyses of pharmacological data and release studies, both in males and in females. Consistently throughout this discussion, we make an effort to distinguish pharmacological effects on sexual behavior from a possible physiological role of dopamine. By pharmacological effects, we mean here drug-induced alterations in behavior that are not the result of the normal actions of synaptically released dopamine in the untreated animal. The conclusion of this endeavor is that pharmacological effects of dopaminergic drugs are variable in both males and females, independently of whether the drugs are administered systemically or intracerebrally. We conclude that the pharmacological data basically reinforce the notion that dopamine is important for motor functions and general arousal. These actions could, in fact, explain most of the effects seen on sexual behavior. Studies of dopamine release, in both males and females, have focused on the nucleus accumbens, a structure with at most a marginal importance for sexual behavior. Since accumbens dopamine release is associated with all kinds of events, aversive as well as appetitive, it can have no specific effect on sexual behavior but promotes arousal and activation of non-specific motor patterns. Preoptic and paraventricular nucleus release of dopamine may have some relationship to mechanisms of ejaculation or to the neuroendocrine consequences of sexual activity or they can be related to other autonomic processes associated with copulation. There is no compelling indication in existing experimental data that dopamine is of any particular importance for sexual motivation. There is experimental evidence showing that it is of no importance for sexual reward.

Parallel bodies of research have described the diverse and complex ways that men understand and construct their masculine identities (often termed "masculinities") and, separately, how adherence to traditional notions of masculinity places men at risk for negative sexual and health outcomes. The goal of this analysis was to bring together these two streams of inquiry. Using data from a national, online sample of 555 heterosexually active young men, we employed latent class analysis (LCA) to detect patterns of masculine identities based on men's endorsement of behavioral and attitudinal indicators of "dominant" masculinity, including sexual attitudes and behaviors. LCA identified four conceptually distinct masculine identity profiles. Two groups, termed the Normative and Normative/Male Activities groups, respectively, constituted 88 % of the sample and were characterized by low levels of adherence to attitudes, sexual scripts, and behaviors consistent with "dominant" masculinity, but differed in their levels of engagement in male-oriented activities (e.g., sports teams). Only eight percent of the sample comprised a masculinity profile consistent with "traditional" ideas about masculinity; this group was labeled Misogynistic because of high levels of sexual assault and violence toward female partners. The remaining four percent constituted a Sex-Focused group, characterized by high numbers of sexual partners, but relatively low endorsement of other indicators of traditional masculinity. Follow-up analyses showed a small number of differences across groups on sexual and substance use health indicators. Findings have implications for sexual and behavioral health interventions and suggest that very few young men embody or endorse rigidly traditional forms of masculinity.

As part of a community based educational campaign to convey the risk of HIV infection and AIDS to commercial sex workers in Jakarta, over 600 male transvestites (WARIA) were questioned about their sexual behavior patterns and their knowledge and attitude towards HIV infection and AIDS. Most expressed a genuine fear about AIDS, but they stated they did not have sufficient information to determine if their risk of infection, at this time, was great enough to command a change in their sexual conduct. Among the group who felt they were not at risk for HIV infection, 40% had 8 or more different sex partners per week. Low risk receptive oral sex, thigh massage (simulated vaginal sex) and masturbation of the client were routine activities but high risk receptive anal sex without condoms was most common. Despite such high risk behavior, the WARIA community remains free of HIV infections. However, if they refuse to accept the endorsement of their peer leaders and they fail to alter their sexual behavior because of an unawareness of their risk, that status will change soon.

The sexual behavior of American college women: an empirical study and an historical survey.

PubMed

Freedman, M B

1965-01-01

A ramdom sample of 49 seniors at an Eastern women's college is used as the basis for a study on the sexual behavior of college women. The women, who were primarily from the upper middle classes, were interviewed several times a year beginning in their freshman year. Sexual behavior was placed into 5 catagories: limited experience, restricted petting, extensive petting, intercourse confined to serious relationships, and uninhibited behavior. Only 6% exhibited unhibited behavior. 16% had had intercourse with 1 or 2 men with whom they had ha d serious relationships. 41% indulged in extensive petting; 27% in restricted petting; and 10% had had limited experience, which is described as simply kissing. Most of the subjects were content with their status quo. Many experienced a liberalization of their attitudes toward sexual behavior for others during the 4-year college experience, but not for themselves. Reasons for remaining a virgin were practical. There was a singular lack of abstract moral or ethical considerations. The only personality scale that related significantly to the catagories for both freshmen and seniors was the Impulse Expression scale--at the .01 level for freshmen and the .05 level for seniors. The data presented are consistent with those of other studies which report the incidence of nonvirginity among college women to be 25% or lower. The incidence of nonvirginity has changed little since the 1930s. However, the incidence of female homosexuality among college women has decreased sharply since the 1920s. It is concluded that American college students may have evolved patterns of sexual behavior that will remain stable. This behavior consists of petting, intercourse among some engaged couples, and early marriage.

Adverse Childhood Experiences and Arrest Patterns in a Sample of Sexual Offenders.

Developmental psychopathology theories suggest that childhood adversity can contribute to antisocial conduct and delinquent activities. The purpose of this study was to explore the influence of adverse childhood experiences (ACE) on arrest patterns in a sample of sexual offenders (N = 740). Higher ACE scores were associated with a variety of arrest outcomes, indicating that the accumulation of early trauma increased the likelihood of versatility and persistence of criminal behavior. Rapists of adults had higher ACE scores, lower levels of specialization, and higher levels of persistence than sex offenders with minor victims only. Child sexual abuse, emotional neglect, and domestic violence in the childhood home were significant predictors of a higher number of sex crime arrests. For measures of nonsexual arrests and criminal versatility, it was the household dysfunction factors-substance abuse, unmarried parents, and incarceration of a family member-that were predictive, suggesting that family dysfunction and a chaotic home environment contributed significantly to increased risk of general criminal behavior. Sex offenders inspire little sympathy in our society but may be among those most in need of trauma-informed models of treatment that recognize the influence of early adversity on maladaptive schema and self-regulation deficits related to criminal behavior. © The Author(s) 2015.

The present study examined longitudinal acculturation patterns, and their associations with family functioning and adolescent risk behaviors, in Hispanic immigrant families. A sample of 266 Hispanic adolescents (mean age 13.4) and their primary parents completed measures of acculturation, family functioning, and adolescent conduct problems, substance use, and sexual behavior at five timepoints. Mixture models yielded three trajectory classes apiece for adolescent and parent acculturation. Assimilated adolescents reported the poorest family functioning, but adolescent assimilation negatively predicted adolescent cigarette smoking, sexual activity, and unprotected sex indirectly through family functioning. Follow-up analyses indicated that discrepancies between adolescent and parent family functioning reports predicted these adolescent outcomes. Results are discussed regarding acculturation trajectories, adolescent risk behavior, and the mediating role of family functioning. PMID:23848416

SEXUAL BEHAVIOR IN MALE RODENTS

The hormonal factors and neural circuitry that control copulation are similar across rodent species, although there are differences in specific behavior patterns. Both estradiol (E) and dihydrotestosterone (DHT) contribute to the activation of mating, although E is more important for copulation and DHT, for genital reflexes. Hormonal activation of the medial preoptic area (MPOA) is most effective, although implants in the medial amygdala (MeA) can also stimulate mounting in castrates. Chemosensory inputs from the main and accessory olfactory systems are the most important stimuli for mating in rodents, especially in hamsters, although genitosensory input also contributes. Dopamine agonists facilitate sexual behavior, and serotonin (5-HT) is generally inhibitory, though certain 5-HT receptor subtypes facilitate erection or ejaculation. Norepinephrine agonists and opiates have dose-dependent effects, with low doses facilitating and high doses inhibiting behavior. PMID:17499249

University students are at risk for acquiring sexually transmitted infections and suffering other negative health outcomes. Sexual health services offer preventive and treatment interventions that aim to reduce these infections and associated health consequences. However, university students often delay or avoid seeking sexual health services. An in-depth understanding of the factors that influence student use of sexual health services is needed to underpin effective sexual health interventions. In this study, we aim to design a behavior change intervention to address university undergraduate students' use of sexual health services at two universities in Nova Scotia, Canada. This mixed methods study consists of three phases that follow a systematic approach to intervention design outlined in the Behaviour Change Wheel. In Phase 1, we examine patterns of sexual health service use among university students in Nova Scotia, Canada, using an existing dataset. In Phase 2, we identify the perceived barriers and enablers to students' use of sexual health services. This will include focus groups with university undergraduate students, health care providers, and university administrators using a semistructured guide, informed by the Capability, Opportunity, Motivation-Behaviour Model and Theoretical Domains Framework. In Phase 3, we identify behavior change techniques and intervention components to develop a theory-based intervention to improve students' use of sexual health services. This study will be completed in March 2018. Results from each phase and the finalized intervention design will be reported in 2018. Previous intervention research to improve university students' use of sexual health services lacks a theoretical assessment of barriers. This study will employ a mixed methods research design to examine university students' use of sexual health service and apply behavior change theory to design a theory- and evidence-based sexual health service intervention. Our approach will provide a comprehensive foundation to co-design a theory-based intervention with service users, health care providers, and administrators to improve sexual health service use among university students and ultimately improve their overall health and well-being. ©Christine Cassidy, Audrey Steenbeek, Donald Langille, Ruth Martin-Misener, Janet Curran.

Testosterone (T) exposure during midgestation differentiates neural circuits controlling sex-specific behaviors and patterns of gonadotropin secretion in male sheep. T acts through androgen receptors (AR) and/or after aromatization to estradiol and binding to estrogen receptors. The current study assessed the role of AR activation in male sexual differentiation. We compared rams that were exposed to the AR antagonist flutamide (Flu) throughout the critical period (i.e. day 30 – 90 of gestation) to control rams and ewes that received no prenatal treatments. The external genitalia of all Flu rams were phenotypically female. Testes were positioned subcutaneously in the inguinal region of the abdomen, exhibited seasonally impaired androgen secretion and were azospermic. Flu rams displayed male-typical precopulatory and mounting behaviors, but could not intromit or ejaculate because they lacked a penis. Flu rams exhibited greater mounting behavior than control rams, and like controls, showed sexual partner preferences for estrous ewes. Neither control nor Flu rams responded to estradiol treatments with displays of female-typical receptive behavior or LH surge responses; whereas all control ewes responded as expected. The ovine sexually dimorphic nucleus in Flu rams was intermediate in volume between control rams and ewes and significantly different from both. . These results indicate that prenatal antiandrogen exposure is not able to block male sexual differentiation in sheep and suggest that compensatory mechanisms intervene to maintain sufficient androgen stimulation during development.

This article examined the associations between three forms of homosexuality-related stigma (enacted, perceived, and internalized homosexual stigmas) with risky sexual behaviors, and to describe the mechanisms of these associations, among men who have sex with men (MSM) in Hanoi, Vietnam. We used respondent-driven sampling (RDS) to recruit 451 MSM into a cross-sectional study conducted from August 2010 to January 2011. Data were adjusted for recruitment patterns due to the RDS approach; logistic regression and path analyses were performed. Participants were young and single; most had attended at least some college. Nine out of ten participants engaged in sexual behaviors at moderate to high risk levels. Compared to those who had no enacted homosexual stigma, men having low and high levels of enacted homosexual stigma, respectively, were 2.23 times (95 % CI 1.35-3.69) and 2.20 times (95 % CI 1.04-4.76) more likely to engage in high levels of sexual risk behaviors. In addition, there was an indirect effect of perceived homosexual stigma and internalized homosexual stigma on sexual risk behaviors through depression and drug and alcohol use. Our study provides valuable information to our understanding of homosexual stigma in Vietnam, highlighting the need for provision of coping skills against stigma to the gay community and addressing drinking and drug use among MSM, to improve the current HIV prevention interventions in Vietnam.

The purpose of this study was to explore the association between sexual orientation and teen pregnancy (before age 20 years) in a U.S. nationally representative cohort of young adult females aged 24-32 years. A total of 5,972 participants in Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health were included. Self-reported sexual orientation identity was categorized as heterosexual, and three sexual minority (SM) groups: mostly heterosexual, bisexual, and lesbian (combining "mostly homosexual" and "100% homosexual"). Stepwise multivariate regression models were fit to compare odds of teen pregnancy and relative risk ratios of timing of teen pregnancy, between heterosexual and SM groups, adjusting for sociodemographic characteristics, sexual victimization history, and sexual risk behaviors. After adjusting for sociodemographics and sexual victimization, bisexual women had significantly higher odds than heterosexual peers of teen pregnancy (odds ratio [OR] = 1.70; 95% confidence interval [CI] = 1.05-2.75); this association was marginally significant after adjusting for sexual risk behaviors. Bisexuals were also more likely to have an early (before age 18 years) teen pregnancy (OR = 2.04; 95% CI = 1.17-3.56). In contrast, lesbian women were significantly less likely to have a teen pregnancy than heterosexual (OR = .47; 95% CI = .23-.97), mostly heterosexual (OR = .46; 95% CI = .21-.99), and bisexual (OR = .29; 95% CI = .12-.71) women in final models. Expanding on extant literature, we found opposing risk patterns for teen pregnancy between bisexual and lesbian women, likely due to distinct patterns of sexual risk taking. Findings suggest that SM-inclusive teen pregnancy prevention efforts tailored to meet the unique needs of SM young women, particularly bisexuals, are needed.

The trade-off between current and future parental investment is often different between males and females. This difference may lead to sexual conflict between parents over care provisioning in animals that breed with multiple mates. One of the most obvious manifestations of sexual conflict over care is offspring desertion whereby one parent deserts the young to increase its reproductive success at the expense of its mate. Offspring desertion is a wide-spread behavior, and its frequency often varies within populations. We studied the consistency of offspring desertion in a small passerine bird, the Eurasian penduline tit Remiz pendulinus, that has an extremely variable breeding system. Both males and females are sequentially polygamous, and a single parent (either the male or the female) incubates the eggs and rears the young. About 28-40% of offspring are abandoned by both parents, and these offspring perish. Here we investigate whether the variation in offspring desertion in a population emerges either by each individual behaving consistently between different broods, or it is driven by the environment. Using a three-year dataset from Southern Hungary we show that offspring desertion by females is consistent between nests. Male desertion, however, depends on ambient environment, because all males desert their nests early in the season and some of them care late in the season. Therefore, within-population variation in parental care emerges by sexually different mechanisms; between-individual variation was responsible for the observed pattern of offspring desertion in females, whereas within-individual variation was responsible for the observed pattern in males. To our knowledge, our study is the first that investigates repeatability of offspring desertion behavior in nature. The contrasting strategies of the sexes imply complex evolutionary trajectories in breeding behavior of penduline tits. Our results raise an intriguing question whether the sexual difference in caring/deserting decisions explain the extreme intensity of sexual conflict in penduline tits that produces a high frequency of biparentally deserted (and thus wasted) offspring.

As sexual medicine evolves, much advancement has been achieved in understanding male sexuality and treating male sexual dysfunction. Less is known about female sexual pattern, the prevalence of sexual problems, and their correlation with confounding factors. To enhance our understanding of female sexuality and the risk factors that contributed to sexual problems in reproductive age women. A cross-sectional survey was conducted in family planning and prepregnancy checkup clinics from December 2007 to December 2009, with 2,146 sexually active Chinese women aged 21 to 40 years completed the entire questionnaire. Prevalence of sexual symptoms, coital frequency, and other sexual behavior-related activities were measured. Overall, 59.0% of respondents had at least one sexual problem. In this sample, 31.8% of respondents reported no desire; 31.7% had arousal problems; 40% had anorgasmia, and 33.8% experienced coital pain for at least 3 months within the past 1 year. Chi-square test showed significant correlation among the four types of sexual problems(P < 0.001). Univariate regression model showed that all sexual symptoms were significantly correlated with unidirectional coitus initiation, low coital frequency, and low foreplay enjoyment. Loglinear model revealed that desire, arousal, and orgasmic problems were correlated with low foreplay enjoyment. Arousal problem was correlated with high acceptance toward pornography and history of medical disease. Coital pain was correlated with secondary education and planning to have more children. Both unidirectional coitus initiation and low coital frequency were major contributors to all four sexual symptoms. Sexual problem is a prevalent health issue among reproductive age women. A number of risk factors are identified, which provide useful direction to the design of counseling and education materials that might help to enhance sexual performance in women. © 2014 International Society for Sexual Medicine.

2010-01-01

Few studies have examined the context of a wide range of risk behaviors among emerging adults (ages 18–25 years), approximately half of whom in the USA enroll in post-secondary educational institutions. The objective of this research was to examine behavioral patterning in weight behaviors (diet and physical activity), substance use, sexual behavior, stress, and sleep among undergraduate students. Health survey data were collected among undergraduates attending a large, public US university (n=2,026). Latent class analysis was used to identify homogeneous, mutually exclusive “classes” (patterns) of ten leading risk behaviors. Resulting classes differed for males and females. Female classes were defined as: (1) poor lifestyle (diet, physical activity, sleep), yet low-risk behaviors (e.g., smoking, binge drinking, sexual risk, drunk driving; 40.0% of females), (2) high risk (high substance use, intoxicated sex, drunk driving, poor diet, inadequate sleep) (24.3%), (3) moderate lifestyle, few risk behaviors (20.4%), (4) “health conscious” (favorable diet/physical activity with some unhealthy weight control; 15.4%). Male classes were: (1) poor lifestyle, low risk (with notably high stress, insufficient sleep, 9.2% of males), (2) high risk (33.6% of males, similar to class 2 in females), (3) moderate lifestyle, low risk (51.0%), and (4) “classic jocks” (high physical activity, binge drinking, 6.2%). To our knowledge, this is among the first research to examine complex lifestyle patterning among college youth, particularly with emphasis on the role of weight-related behaviors. These findings have important implications for targeting much needed health promotion strategies among emerging adults and college youth. PMID:19499339

Although several studies have characterized patterns and predictors of continued risky sexual behavior in HIV-infected rural persons, far less research has evaluated interventions to reduce risky sex in this group. This pilot randomized clinical trial compared 2 brief telephone-administered interventions designed to reduce continued risky sexual behaviors in HIV-infected rural persons. Participants were 79 HIV-infected rural persons who reported 1 or more occasions of unprotected anal, vaginal, or oral sex in the past 2 months. Participants were recruited through AIDS service organizations in rural areas of 27 states and assigned randomly to either a 2-session, motivational interviewing plus skills-building intervention (i.e., integrated intervention; n = 48) or a 2-session, skills-building only comparison intervention (n = 31). Participants completed self-report measures of sexual behaviors and factors related to risky sex at preintervention and 2-month follow-up. Before enrolling into the intervention, 37% of participants had 2 or more sexual partners in the past 2 months, 29% had sex with 1 or more partners without knowing their partners' HIV serostatus, and almost one-third of participants located sex partners in high-risk environments (e.g., public parks, roadside rest areas). A 2 x 2 repeated measures multivariate analyses of variance found that integrated intervention participants reported greater increases in risk-reduction motivation and greater increases in condom-protected vaginal and oral intercourse occasions at follow-up compared to skills-building only participants. Brief telephone-administered interventions that integrate motivational interviewing with skills-building show potential to reduce risky sexual behaviors in HIV-infected rural persons. Additional and large-scale evaluations of this intervention approach appear warranted.

Little is known about people with social anxiety disorder (SAD) who are not behaviorally inhibited. To advance knowledge on phenomenology, functional impairment, and treatment seeking, we investigated whether engaging in risk-prone behaviors accounts for heterogeneous outcomes in people with SAD. Using the National Comorbidity Survey-Replication (NCS-R) dataset, our analyses focused on people with current (N = 679) or lifetime (N = 1143) SAD diagnoses. Using latent class analysis on NCS-R risk-prone behavior items, results supported two SAD classes: (1) a pattern of behavioral inhibition and risk aversion and (2) an atypical pattern of high anger and aggression, and moderate/high sexual impulsivity and substance use problems. An atypical pattern of risk-prone behaviors was associated with greater functional impairment, less education and income, younger age, and particular psychiatric comorbidities. Results could not be subsumed by the severity, type, or number of social fears, or comorbid anxiety or mood disorders. Conclusions about the nature, course, and treatment of SAD may be compromised by not attending to heterogeneity in behavior patterns. PMID:19345933

Grindr, a geosocial smartphone application, is a networking medium for men who have sex with men. Although three quarters of young men who have sex with men (YMSM) Grindr users report having sex with a Grindr-met partner, the correlates of risky sexual behavior with Grindr-met partners are unknown. A randomly selected sample of 18- to 24-year-old, Grindr-using YMSM completed an anonymous online questionnaire assessing patterns of Grindr use and sexual behavior with their last Grindr-met partners. Of the 146 YMSM who reported having sex with Grindr-met partners, 20% had unprotected anal intercourse (UAI) at last sex with their Grindr-met partner. In the multivariable model, YMSM who used Grindr for at least one year showed naked chest/abs in their profile photo, and reported more past month Grindr-met partners were more likely to report UAI. These findings suggest that familiarity with the app was associated with YMSM's UAI with Grindr-met partners. Moreover, sexualized profile photos (i.e., naked chest/abs) may be associated with sexual risk-taking behaviors. HIV prevention interventions delivered or linked through such apps should target individuals who are longer/frequent users and who present sexualized profiles.

A prospective 2-year examination of cognitive and behavioral correlates of provoked vestibulodynia outcomes.

Provoked vestibulodynia (PVD) is a common genital pain disorder in women that is associated with sexual dysfunction and lowered sexual satisfaction. A potentially applicable cognitive-behavioral model of chronic pain and disability is the fear-avoidance model (FAM) of pain. The FAM posits that cognitive variables, such as pain catastrophizing, fear, and anxiety lead to avoidance of pain-provoking behaviors (eg, intercourse), resulting in continued pain and disability. Although some of the FAM variables have been shown to be associated with PVD pain and sexuality outcomes, the model as a whole has never been tested in this population. An additional protective factor, pain self-efficacy (SE), is also associated with PVD, but has not been tested within the FAM model. Using a 2-year longitudinal design, we examine (1) whether initial levels (T1) of the independent FAM variables and pain SE were associated with changes in pain, sexual function, and sexual satisfaction over the 2-year time period; (2) the prospective contribution of changes in cognitive-affective (FAM) variables to changes in pain, and sexuality outcomes; and (3) whether these were mediated by behavioral change (avoidance of intercourse). A sample of 222 women with PVD completed self-report measures of FAM variables, SE, pain, sexual function, and sexual satisfaction at time 1 and at a 2-year follow-up. Structural equation modeling with Latent Difference Scores was used to examine changes and to examine mediation between variables. Questionnaires included the Pain Catastrophizing Scale, McGill Pain Questionnaire, Trait Anxiety Inventory, Pain Self-Efficacy Scale, and Global Measure of Sexual Satisfaction, Female Sexual Function Index. Participants who reported higher SE at T1 reported greater declines in pain, greater increases in sexual satisfaction, and greater declines in sexual function over the 2 time points. The overall change model did not support the FAM using negative cognitive-affective variables. Only increases in pain SE were associated with reductions in pain intensity. The relationship between changes in SE and changes in pain was partially mediated through changes in avoidance (more intercourse attempts). The same pattern of results was found for changes in sexual satisfaction as the outcome, and a partial mediation effect was found. There were no significant predictors of changes in sexual function other than T1 SE. Changes in both cognitive and behavioral variables were significantly associated with improved pain and sexual satisfaction outcomes. However, it was the positive changes in SE that better predicted changes in avoidance behavior, pain, and sexual satisfaction. Cognitive-behavior therapy is often focused on changing negative pain-related cognitions to reduce avoidance and pain, but the present results demonstrate the potential importance of bolstering positive self-beliefs as well. Indeed, before engaging in exposure therapies, SE beliefs should be assessed and potentially targeted to improve adherence to exposure strategies.

Coming out for a third time: transmen, sexual orientation, and identity.

Female-to-male (FTM) transgender persons are often assumed to have been lesbian in sexual orientation prior to transition and to have maintained a primary attraction for women after transition. However, limited research and anecdotal information from clinicians who work with FTM have indicated that many identify as gay men post-transition. This article described the results of a qualitative study that employed interviews with 17 FTM in order to understand their experience of transition and sexual orientation. Of the 17 participants, seven identified as lesbian prior to transition, three as heterosexual, and seven as bisexual or queer. After transition, 10 identified as gay men and the remaining seven identified as bisexual or queer. Four patterns of sexual behavior emerged from the data and were described and discussed. These patterns were named steadfast, aligned, shifted, and fluid. These findings bring additional options to the belief that there are two distinct types of transgender: a homosexual subtype and a nonhomosexual subtype.

Pleasure, power, and inequality: incorporating sexuality into research on contraceptive use.

PubMed

Higgins, Jenny A; Hirsch, Jennifer S

2008-10-01

We know surprisingly little about how contraception affects sexual enjoyment and functioning (and vice versa), particularly for women. What do people seek from sex, and how do sexual experiences shape contraceptive use? We draw on qualitative data to make 3 points. First, pleasure varies. Both women and men reported multiple aspects of enjoyment, of which physical pleasure was only one. Second, pleasure matters. Clear links exist between the forms of pleasure respondents seek and their contraceptive practices. Third, pleasure intersects with power and social inequality. Both gender and social class shape sexual preferences and contraceptive use patterns. These findings call for a reframing of behavioral models that explain why people use (or do not use) contraception.

Sexually transmitted infection (STI) surveillance is vital for tracking the scale and pattern of epidemics; however, it often lacks data on the underlying drivers of STIs. This study aimed to assess the acceptability and feasibility of implementing a bio-behavioral enhanced surveillance tool, comprising a self-administered Web-based survey among sexual health clinic attendees, as well as linking this to their electronic health records (EHR) held in England's national STI surveillance system. Staff from 19 purposively selected sexual health clinics across England and men who have sex with men and black Caribbeans, because of high STI burden among these groups, were interviewed to assess the acceptability of the proposed bio-behavioral enhanced surveillance tool. Subsequently, sexual health clinic staff invited all attendees to complete a Web-based survey on drivers of STI risk using a study tablet or participants' own digital device. They recorded the number of attendees invited and participants' clinic numbers, which were used to link survey data to the EHR. Participants' online consent was obtained, separately for survey participation and linkage. In postimplementation phase, sexual health clinic staff were reinterviewed to assess the feasibility of implementing the bio-behavioral enhanced surveillance tool. Acceptability and feasibility of implementing the bio-behavioral enhanced surveillance tool were assessed by analyzing these qualitative and quantitative data. Prior to implementation of the bio-behavioral enhanced surveillance tool, sexual health clinic staff and attendees emphasized the importance of free internet/Wi-Fi access, confidentiality, and anonymity for increasing the acceptability of the bio-behavioral enhanced surveillance tool among attendees. Implementation of the bio-behavioral enhanced surveillance tool across sexual health clinics varied considerably and was influenced by sexual health clinics' culture of prioritization of research and innovation and availability of resources for implementing the surveys. Of the 7367 attendees invited, 85.28% (6283) agreed to participate. Of these, 72.97% (4585/6283) consented to participate in the survey, and 70.62% (4437/6283) were eligible and completed it. Of these, 91.19% (4046/4437) consented to EHR linkage, which did not differ by age or gender but was higher among gay/bisexual men than heterosexual men (95.50%, 722/756 vs 88.31%, 1073/1215; P<.003) and lower among black Caribbeans than white participants (87.25%, 568/651 vs 93.89%, 2181/2323; P<.002). Linkage was achieved for 88.88% (3596/4046) of consenting participants. Implementing a bio-behavioral enhanced surveillance tool in sexual health clinics was feasible and acceptable to staff and groups at STI risk; however, ensuring participants' confidentiality and anonymity and availability of resources is vital. Bio-behavioral enhanced surveillance tools could enable timely collection of detailed behavioral data for effective commissioning of sexual health services. ©Sonali Wayal, David Reid, Paula B Blomquist, Peter Weatherburn, Catherine H Mercer, Gwenda Hughes.

Objectives. We examined correlations between gender, race, sexual identity, and technology use, and patterns of cyberbullying experiences and behaviors among middle-school students. Methods. We collected a probability sample of 1285 students alongside the 2012 Youth Risk Behavior Survey in Los Angeles Unified School District middle schools. We used logistic regressions to assess the correlates of being a cyberbully perpetrator, victim, and perpetrator–victim (i.e., bidirectional cyberbullying behavior). Results. In this sample, 6.6% reported being a cyberbully victim, 5.0% reported being a perpetrator, and 4.3% reported being a perpetrator–victim. Cyberbullying behavior frequently occurred on Facebook or via text messaging. Cyberbully perpetrators, victims, and perpetrators–victims all were more likely to report using the Internet for at least 3 hours per day. Sexual-minority students and students who texted at least 50 times per day were more likely to report cyberbullying victimization. Girls were more likely to report being perpetrators–victims. Conclusions. Cyberbullying interventions should account for gender and sexual identity, as well as the possible benefits of educational interventions for intensive Internet users and frequent texters.

This study sought to study consumption patterns of gay-oriented sexually explicit media (SEM) by men who have sex with men (MSM); and to investigate a hypothesized relationship between gay SEM consumption and HIV risk behavior. Participants were 1391 MSM living in the US, recruited online to complete a SEM consumption and sexual risk survey. Almost all (98.5%) reported some gay SEM exposure over the last 90 days. While 41% reported a preference to watch actors perform anal sex without condoms (termed “bareback SEM”), 17% preferred to actors perform anal sex with condoms (termed “safer sex SEM”) and 42% reported no preference. Overall SEM consumption was not associated with HIV risk; however participants who watched more bareback SEM reported significantly greater odds of engaging in risk behavior. The results suggest that a preference for bareback SEM is associated with engaging in risk behavior. More research to understand how MSM develop and maintain preferences in viewing SEM, and to identify new ways to use SEM in HIV prevention, is recommended. PMID:23564010

We assessed the prevalence, incidence, and correlates of substance use among Asian American individuals transitioning from adolescence to young adulthood. Data were obtained from the National Longitudinal Study of Adolescent Health, Wave II (1996) and Wave III (2001). Information on substance use was abstracted from a nationally representative sample of 1108 Asian Americans and Pacific Islanders (AAPIs) from both Waves. Weighted prevalence, incidence, and patterns of smoking, binge drinking, marijuana use, and other drug use were analyzed by sexual orientation and gender. Multiple logistic regression analyses were conducted to investigate the unique contribution of being a sexual minority in relation to four types of substance use by gender. A link between sexual orientation and substance use behaviors among AAPIs did not emerge until young adulthood. Significant increases in the incidence and prevalence of all four types of substance use (tobacco, binge drinking, marijuana, and other drugs) were found among sexual minority AAPIs. Specifically being an AAPI sexual minority young woman, compared with being a heterosexual young woman, a heterosexual young man, or a sexual minority young man, was significantly associated with substance use after controlling for demographic characteristics, problem behaviors, and substance use during adolescence. Also the highest prevalence of substance use was found among AAPI sexual minority women. These findings add greater urgency to addressing the role of sexual orientation in designing substance abuse programs.

Intrasexual competition in females: evidence for sexual selection?

PubMed

Rosvall, Kimberly A

2011-11-01

In spite of recent interest in sexual selection in females, debate exists over whether traits that influence female-female competition are sexually selected. This review uses female-female aggressive behavior as a model behavioral trait for understanding the evolutionary mechanisms promoting intrasexual competition, focusing especially on sexual selection. I employ a broad definition of sexual selection, whereby traits that influence competition for mates are sexually selected, whereas those that directly influence fecundity or offspring survival are naturally selected. Drawing examples from across animal taxa, including humans, I examine 4 predictions about female intrasexual competition based on the abundance of resources, the availability of males, and the direct or indirect benefits those males provide. These patterns reveal a key sex difference in sexual selection: Although females may compete for the number of mates, they appear to compete more so for access to high-quality mates that provide direct and indirect (genetic) benefits. As is the case in males, intrasexual selection in females also includes competition for essential resources required for access to mates. If mate quality affects the magnitude of mating success, then restricting sexual selection to competition for quantity of mates may ignore important components of fitness in females and underestimate the role of sexual selection in shaping female phenotype. In the future, understanding sex differences in sexual selection will require further exploration of the extent of mutual intrasexual competition and the incorporation of quality of mating success into the study of sexual selection in both sexes.

Hispanic perspectives on sexual harassment and social support.

Cortina, Lilia M

2004-05-01

Bridging the social support, sexual victimization, and cultural psychology literatures, this study examines social-support processes in the context of sexual harassment and Hispanic American culture. Surveys were administered to a community sample of Hispanic American working women, 249 of whom described some encounter with sexual harassment at work. Regression results provided mixed backing for hypotheses about support-seeking behavior, which appeared largely dependent on the social power of the harassment perpetrator. Additional findings upheld predictions about support-perception patterns; harassed women perceived more supportive social reactions when they turned to informal networks of friends and family, but responses were less positive when they turned to formal, organizational sources. Finally, as expected, perceived support and acculturation interacted to moderate relations between sexual harassment and job satisfaction. The article concludes with implications for research and interventions related to social support and sexual harassment.

Sexually selected sex differences in competitiveness explain sex differences in changes in drinking game participation.

Drinking games are a risk factor for behavioral and health problems among university students. Previous cross-sectional research by Hone, Carter, and McCullough (2013) replicated well-established sex differences in drinking game behaviors (i.e., that men are more active drinking game participants than are women) and university drinking problems more generally. Hone et al. (2013) also found that these male-specific behavioral patterns are attributable in part to the fact that men's generally unrestricted sexual strategies, plus their social competitiveness, motivate them to participate in drinking games to display their fortitude and compete with same-sex rivals. Here, the authors conducted a study to evaluate with greater causal rigor whether sex differences in sexual restrictedness and social competitiveness-and sex differences in motivations for participating in drinking games in particular-are partially responsible for the sex differences in university students' drinking game behaviors and drinking problems. Sex differences in changes in frequency of drinking game participation were partially mediated by competitive motivations for participating in drinking games and by the effects of social competitiveness on competitive drinking game motivation. These findings lend additional support to the proposition that participation in drinking games is motivated in part by their suitability as a venue for sexual competition in university students' day-to-day lives.

Psychiatric symptom typology in a sample of youth receiving substance abuse treatment services: associations with self-reported child maltreatment and sexual risk behaviors.

2011-11-01

Latent profile analysis (LPA) was used to classify 394 adolescents undergoing substance use treatment, based on past year psychiatric symptoms. Relations between profile membership and (a) self-reported childhood maltreatment experiences and (b) current sexual risk behavior were examined. LPA generated three psychiatric symptom profiles: Low-, High- Alcohol-, and High- Internalizing Symptoms profiles. Analyses identified significant associations between profile membership and childhood sexual abuse and emotional neglect ratings, as well as co-occurring sex with substance use and unprotected intercourse. Profiles with elevated psychiatric symptom scores (e.g., internalizing problems, alcohol abuse and dependence symptoms) and more severe maltreatment histories reported higher scores for behavioral risk factors for HIV/STI exposure. Heterogeneity in psychiatric symptom patterns among youth receiving substance use treatment services, and prior histories of childhood maltreatment, have significant implications for the design and delivery of HIV/STI prevention programs to this population.

Auditory experience controls the maturation of song discrimination and sexual response in Drosophila

In birds and higher mammals, auditory experience during development is critical to discriminate sound patterns in adulthood. However, the neural and molecular nature of this acquired ability remains elusive. In fruit flies, acoustic perception has been thought to be innate. Here we report, surprisingly, that auditory experience of a species-specific courtship song in developing Drosophila shapes adult song perception and resultant sexual behavior. Preferences in the song-response behaviors of both males and females were tuned by social acoustic exposure during development. We examined the molecular and cellular determinants of this social acoustic learning and found that GABA signaling acting on the GABAA receptor Rdl in the pC1 neurons, the integration node for courtship stimuli, regulated auditory tuning and sexual behavior. These findings demonstrate that maturation of auditory perception in flies is unexpectedly plastic and is acquired socially, providing a model to investigate how song learning regulates mating preference in insects.

Behavioral surveys help interpret the magnitude of HIV/AIDS. We analyzed indicators of knowledge on HIV/AIDS and condom use among sub populations selected for behavioral surveillance in Ethiopia. We used 2005 HIV/AIDS behavioral data from ten target groups. These were female sex workers, defense forces, police force, pastoralists, truck drivers, intercity bus drivers, road construction workers, teachers, factory workers and people in ANC catchment areas. Data from 14,524 individuals were analyzed. The majority were males (63.6%). Overall, knowledge of the three preventive methods, misconceptions and comprehensive knowledge was 57%, 75% and 18.5%, respectively. Female sex workers and the defense force showed some behavioral change in using a condom during the most recent sexual encounter and consistently used a condom with non-regular sexual partners and paying partners. Women, pastoralists and the illiterate were less likely to use condom. Misconceptions about the transmission of HIV were high and comprehensive knowledge about HIV & AIDS was low, particularly among pastoralists. Consistent condom use and condom use during the last sexual encounter were high among both female sex workers and defense force employees, both with paying and non-regular sexual partners. This might be a positive sign, though a considerable proportion in each target group did not report using a condom during sex with non-regular partners.

Shek, D T L

2013-06-01

The present study examined the prevalence, changes, and demographic as well as psychosocial correlates of sexual behavior and intention to engage in sexual behavior in early adolescents in Hong Kong, with sexual behavior indexed by sexual intercourse. Three waves of longitudinal data on sexual intercourse, intention to engage in sexual intercourse, family functioning, and positive youth development were collected from 28 secondary schools in Hong Kong. There were significant influences of grade and gender on adolescent sexual behavior or intention to engage in sexual behavior. Significant main effects of immigration status on sexual behavior were also found. While no effect of family economic background was found, effect of family intactness existed for sexual behavior. Family functioning and positive youth development at Grade 7 were negatively associated with students' sexual behavior and intention to engage in sexual behavior at Grade 9. Grade, gender, immigration status, and family intactness were related to sexual behavior and/or intention to engage in sexual behavior in junior secondary school students. Promoting positive youth development and family functioning could serve as protective factors to reduce sexual behavior and intention to engage in sexual behavior in Chinese early adolescents in Hong Kong.

Sexting, sending, or receiving sexually suggestive or explicit messages/photos/videos, have not been studied extensively. The aims of this study is to understand factors associated with sexting among minority (e.g., African- American, Hispanic) emerging adult males and the association between sexting and sexual risk. We recruited 119 emerging adult heterosexual males and assessed sexting and sexual risk behaviors. Fifty-four percent of participants sent a sext, and 70% received a sext. Participants were more likely to sext with casual partners than with steady partners. Multiple regression analyses showed that participants who sent sexts to steady partners had significantly more unprotected vaginal intercourse and oral sex. Participants who sent sexts to casual partners had significantly more partners, and participants who received sexts from casual partners had significantly more unprotected oral sex and sex while on substances. We found that sexting is a frequent and reciprocal behavior among emerging adults, and there were different patterns of significance for sexts with casual and steady partners.

Beyond magic traits: Multimodal mating cues in Heliconius butterflies.

PubMed

Mérot, Claire; Frérot, Brigitte; Leppik, Ene; Joron, Mathieu

2015-11-01

Species coexistence involves the evolution of reproductive barriers opposing gene flow. Heliconius butterflies display colorful patterns affecting mate choice and survival through warning signaling and mimicry. These patterns are called "magic traits" for speciation because divergent natural selection may promote mimicry shifts in pattern whose role as mating cue facilitates reproductive isolation. By contrast, between comimetic species, natural selection promotes pattern convergence. We addressed whether visual convergence interferes with reproductive isolation by testing for sexual isolation between two closely related species with similar patterns, H. timareta thelxinoe and H. melpomene amaryllis. Experiments with models confirmed visual attraction based on wing phenotype, leading to indiscriminate approach. Nevertheless, mate choice experiments showed assortative mating. Monitoring male behavior toward live females revealed asymmetry in male preference, H. melpomene males courting both species equally while H. timareta males strongly preferred conspecifics. Experiments with hybrid males suggested an important genetic component for such asymmetry. Behavioral observations support a key role for short-distance cues in determining male choice in H. timareta. Scents extracts from wings and genitalia revealed interspecific divergence in chemical signatures, and hybrid female scent composition was significantly associated with courtship intensity by H. timareta males, providing candidate chemical mating cues involved in sexual isolation. © 2015 The Author(s).

A new standard of sexual behavior? Are claims associated with the "hookup culture" supported by general social survey data?

PubMed

Monto, Martin A; Carey, Anna G

2014-01-01

Popular media have described intimate relationships among contemporary college students as dominated by a pervasive sexual "hookup culture," implying that students are involved in frequent sexual encounters pursued by both participants without the expectation of a continuing relationship. The hookup culture has been described as "a nationwide phenomenon that has largely replaced traditional dating on college campuses" (Bogle, 2008 , p. 5). We tested whether these claims are supported among young adults (18-25) who had completed at least one year of college. Contrasting 1988-1996 waves of the General Social Survey with 2004-2012 waves, we found respondents from the current era did not report more sexual partners since age 18, more frequent sex, or more partners during the past year than respondents from the earlier era. Sexually active respondents from the current era were more likely than those from the earlier era to report sex with a casual date/pickup or friend, and less likely to report sex with a spouse/regular partner. These modest changes are consistent with cultural shifts in the "scripts" and terminology surrounding sexuality. We find no evidence of substantial changes in sexual behavior that would indicate a new or pervasive pattern of non-relational sex among contemporary college students.

Although frequently cited as being at high risk for HIV/STI transmission, little is known about behaviorally bisexual men’s patterns and experiences of condom use and nonuse with male and female sexual partners. Using a variety of recruitment techniques informed by a Community Advisory Committee, a total of 77 behaviorally bisexual men were recruited from Indianapolis, Indiana to participate in semi-structured interviews focused on sexual health. Qualitative data were collected containing detailed information on their patterns and experiences of condom use and nonuse with both male and female partners. Participants described numerous commonly reported barriers for consistent condom use, as well as distinct bisexual-specific barriers. The majority reported consistent condom use with male and female casual partners, but many who did not use condoms described doing so in the context of ongoing relationships. In addition, participants provided reasons for condom use and nonuse that varied based on the gender of the partner and the type of relationship with the partner. Future interventions focused on increasing condom use among behaviorally bisexual men should take into account the unique complexities of gender and relationship configurations in this distinct population.

Dopamine and serotonin: influences on male sexual behavior.

PubMed

Hull, Elaine M; Muschamp, John W; Sato, Satoru

2004-11-15

Steroid hormones regulate sexual behavior primarily by slow, genomically mediated effects. These effects are realized, in part, by enhancing the processing of relevant sensory stimuli, altering the synthesis, release, and/or receptors for neurotransmitters in integrative areas, and increasing the responsiveness of appropriate motor outputs. Dopamine has facilitative effects on sexual motivation, copulatory proficiency, and genital reflexes. Dopamine in the nigrostriatal tract influences motor activity; in the mesolimbic tract it activates numerous motivated behaviors, including copulation; in the medial preoptic area (MPOA) it controls genital reflexes, copulatory patterns, and specifically sexual motivation. Testosterone increases nitric oxide synthase in the MPOA; nitric oxide increases basal and female-stimulated dopamine release, which in turn facilitates copulation and genital reflexes. Serotonin (5-HT) is primarily inhibitory, although stimulation of 5-HT(2C) receptors increases erections and inhibits ejaculation, whereas stimulation of 5-HT(1A) receptors has the opposite effects: facilitation of ejaculation and, in some circumstances, inhibition of erection. 5-HT is released in the anterior lateral hypothalamus at the time of ejaculation. Microinjections of selective serotonin reuptake inhibitors there delay the onset of copulation and delay ejaculation after copulation begins. One means for this inhibition is a decrease in dopamine release in the mesolimbic tract.

Associations Between Latent Classes of Interpersonal Polyvictimization and Polyperpetration and Sexual Risk Behaviors Among Young Pregnant Couples: A Dyadic Analysis.

Interpersonal violence victimization and perpetration have been associated with sexual risk behaviors among adolescents and young adults, but research is lacking on: (1) how patterns of interpersonal polyvictimization and polyperpetration are associated with sexual risk among young pregnant couples, and (2) how individual and partner experiences of violence differentially impact sexual risk. The current analyses used baseline data from a longitudinal study that followed 296 pregnant young couples from pregnancy to 12 months postpartum. Couples were recruited at obstetrics and gynecology clinics, and an ultrasound clinic in the U.S. Latent class analysis identified subgroups based on polyvictimization and polyperpetration. Using the Actor-Partner Interdependence Model, path analyses assessed actor-partner effects of class membership on sexual risk. Three latent classes were used for women: Class 1: Polyvictim-Polyperpetrator; Class 2: Nonvictim-Nonperpetrator; and Class 3: Community and Prior IPV Victim. Four latent classes were used for men: Class 1: Community and Prior IPV Victim; Class 2: Polyvictim-Nonpartner Perpetrator; Class 3: Prior IPV and Peer Victim; and Class 4: Nonvictim-Nonperpetrator. Path analyses revealed that females in Class 2 and their male partners had higher condom use than females in Class 3. Males in Class 2 had more sexual partners than males in Class 1. Among nonmonogamous couples, males in Class 2 were less likely to be involved with a female partner reporting unprotected sex than males in Class 1. Among nonmonogamous couples, females in Class 2 had more acts of unprotected sex than females in Class 1. Males in Class 4 were less likely to have concurrent sexual partners compared to males in Class 1. Risk reduction interventions should address both victimization and perpetration. Additional research is needed to understand how mechanisms driving differential sexual risk by patterns of interpersonal polyvictimization and polyperpetration.

Notions of ideal manhood in South Africa are potentially prescriptive of male sexuality thus accounting for the behaviors which may lead to men being at greater HIV risk. We tested the hypothesis that gender and relationship constructs are associated with condom use among young men living in rural South Africa. 1219 men aged 15-26 years completed a cross-sectional baseline survey from an IsiXhosa questionnaire asking about sexual behaviour and relationships. Univariate and bivariate analyses described condom use patterns and explanatory variables, and multinomial regression modeling assessed the factors associated with inconsistent versus consistent and non-condom use. 47.7% of men never used condoms, when 36.9% were inconsistent and 15.4% were consistent with any partner in the past year. Condom use patterns differed in association with gender relations attitudes: never users were significantly more conservative than inconsistent or consistent users. Three gender positions emerged indicating that inconsistent users were most physically/sexually violent and sexually risky; never users had more conservative gender attitudes but were less violent and sexually risky; and consistent users were less conservative, less violent and sexually risky with notably fewer sexual partners than inconsistent users. The confluence of conservative gender attitudes, perpetration of violence against women and sexual risk taking distinguished inconsistent condom users as the most risky compared to never condom users, and rendered inconsistent use one of the basic negative attributes of dominant masculinities in the Eastern Cape, South Africa. This finding is important for the design of HIV prevention and gender equity interventions and emphasizes the need for a wider roll-out of interventions that promote progressive and healthy masculine practices in the country.

Hermaphroditism, associated with territoriality and dominance behavior, is common in the marine environment. While male sex-specific coloration patterns have been documented in groupers, particularly during the spawning season, few data regarding social structure and the context for these color displays are available. In the present study, we define the social structure and male typical behavior of rock hind (Epinephelus adscensionis) in the wild. In addition, we detail the captive conditions and time period necessary to induce the onset of the sex-specific coloration and sexual change. At six oil production platform locations in the Gulf of Mexico, rock hind social group size and typical male rock hind social behavior were documented. We observed a rapid temporary color display in rock hind that could be turned on and off within three seconds and was used for confronting territory intruders and displays of aggression towards females. The male-specific “tuxedo” pattern consists of a bright yellow tail, a body with alternating dark brown and white patches and a dark bar extending from the upper mandible to the operculum. Identification and size ranges of male, female and intersex fish collected from oil platforms were determined in conjunction with gonadal histology. Rock hind social order is haremic with one dominant male defending a territory and a linear dominance hierarchy among individuals. In five captive experiments, the largest remaining female rock hind displayed the male specific color pattern within 32d after dominant male removal from the social group. To our knowledge, this is the first evidence in a grouper species of color patterning used to display territoriality and dominance outside of spawning aggregations. The behavioral paradigm described here is a key advance that will enable mechanistic studies of this complex sex change process. PMID:21647429

Parallel evolution of sexual isolation in sticklebacks.

Mechanisms of speciation are not well understood, despite decades of study. Recent work has focused on how natural and sexual selection cause sexual isolation. Here, we investigate the roles of divergent natural and sexual selection in the evolution of sexual isolation between sympatric species of threespine sticklebacks. We test the importance of morphological and behavioral traits in conferring sexual isolation and examine to what extent these traits have diverged in parallel between multiple, independently evolved species pairs. We use the patterns of evolution in ecological and mating traits to infer the likely nature of selection on sexual isolation. Strong parallel evolution implicates ecologically based divergent natural and/or sexual selection, whereas arbitrary directionality implicates nonecological sexual selection or drift. In multiple pairs we find that sexual isolation arises in the same way: assortative mating on body size and asymmetric isolation due to male nuptial color. Body size and color have diverged in a strongly parallel manner, similar to ecological traits. The data implicate ecologically based divergent natural and sexual selection as engines of speciation in this group.

Theory and research on HIV and among men who have sex with men (MSM) have long suggested the importance of non-residential locations in defining structural exposures. Despite this, most studies within these fields define place as a residential context, neglecting the potential influence of non-residential locations on HIV-related outcomes. The concept of activity spaces, defined as a set of locations to which an individual is routinely exposed, represents one theoretical basis for addressing this potential imbalance. Using a one-time online survey to collect demographic, behavioral, and spatial data from MSM, this paper describes activity spaces and examines correlates of this spatial variation. We used latent class analysis to identify categories of activity spaces using spatial data on home, routine, potential sexual risk, and HIV prevention locations. We then assessed individual and area-level covariates for their associations with these categories. Classes were distinguished by the degree of spatial variation in routine and prevention behaviors (which were the same within each class) and in sexual risk behaviors (i.e., sex locations and locations of meeting sex partners). Partner type (e.g. casual or main) represented a key correlate of the activity space. In this early examination of activity spaces in an online sample of MSM, patterns of spatial behavior represent further evidence of significant spatial variation in locations of routine, potential HIV sexual risk, and HIV prevention behaviors among MSM. Although prevention behaviors tend to have similar geographic variation as routine behaviors, locations where men engage in potentially high-risk behaviors may be more spatially focused for some MSM than for others.

Background Evidence suggests there are important sexual-orientation differences in alcohol consumption, particularly among women. Little is known about where gay/lesbian and bisexual college students drink or differences in patterns of alcohol use between heterosexual, gay/lesbian, and bisexual students. The goal of this analysis was to examine patterns of alcohol consumption—including drinking prevalence, quantity, frequency, and contexts of use—by sexual orientation. Methods Data on sexual identity, gender, drinking behaviors, and drinking contexts were examined from repeated cross-sectional samples of undergraduate students attending 14 public California universities from 2003–2011 (n=58,903). Multivariable statistical techniques were employed to examine sexual-orientation differences stratified by gender. Results Gay males, lesbians, and bisexual females were significantly more likely to report drinking alcohol in the current semester than their same-gender heterosexual peers (relative risks ranged from 1.07 to 1.10, p-values<0.01). Among current drinkers, bisexual females consumed 7 or more drinks and lesbians consumed 10 or more drinks on significantly more days than heterosexual females. On the other hand, gay male drinkers consumed 8 or more drinks on significantly fewer days than heterosexual male drinkers. Compared to their same-gender heterosexual peers: lesbian/gay and bisexual students drank less frequently at Greek parties (incidence rate ratios [IRRs] ranged from 0.52 to 0.73, p-values<0.01); lesbians (IRR=0.84, p=0.043) and bisexual males (IRR=0.82, p=0.009) drank less frequently at off-campus parties; and gay males drank more frequently outdoors (IRR=1.63, p<0.001) and at bars/restaurants (IRR=1.21, p=0.013). Conclusions Alcohol prevention programs and future research should consider sexual-orientation differences in drinking patterns and drinking contexts. PMID:26827292

Child Sexual Behaviors in School Context: Age and Gender Differences.

Miragoli, Sarah; Camisasca, Elena; Di Blasio, Paola

2017-01-01

The main purpose of the study was to explore the child sexual behaviors that Italian teachers have observed in the school context. A representative sample of 227 children, from 5 to 10 years old, was rated by their teachers through the Child Sexual Behavior Inventory. Frequencies of sexual behaviors among children aged 5 to 6, 7 to 8, and 9 to 10 are presented. Younger children showed a broader range of sexual behaviors that decrease with the growing age, such as males in comparison to females. Moreover, findings showed that child sexual behavior is not only related to age and gender but also to family characteristics. These results suggested that child sexual behaviors reported by teachers through the Child Sexual Behavior Inventory may provide useful information about the development of children's sexuality. The knowledge of age appropriate sexual behaviors can help teachers discern normal sexual behaviors from problematic sexual behaviors.

Medial prefrontal cortex lesions in the female rat affect sexual and maternal behavior and their sequential organization.

2007-06-01

Temporal sequences of sexual and maternal behaviors in female rats and their correlation with each other and with performance on a sensory-motor gating response inhibition task assessed by prepulse inhibition (PPI) were investigated following medial prefrontal cortex (mPFC) lesions. Following excitotoxic mPFC (n = 10) or sham (n = 9) lesions, sexual behaviors across the ovarian cycle were scored. After mating and parturition, maternal interactions were scored until pups reached postnatal Day 10. After resumption of the ovarian cycle, the female rats were tested for PPI. Compared with sham lesions, mPFC lesions impaired proceptive behaviors and some maternal behaviors (e.g., pup retrieval, pup licking) but did not affect others (e.g., nest building, pup mouthing). Lesions disrupted temporal sequences of solicitations (number of male orientations followed, within 4 s, by a level change) and pup retrievals (number of pup retrievals followed, within 5 s, by another retrieval). These sequential behavior patterns were significantly correlated with each other and with PPI. However, when PPI effects were partialled out, group differences were less strong, but persisted. This study demonstrated that mPFC manipulations affect actions rich in sequential structure in response to biologically relevant stimuli. Copyright (c) 2007 APA, all rights reserved.

Sexual Harassment, Psychological Distress, and Problematic Drinking Behavior Among College Students: An Examination of Reciprocal Causal Relations.

2017-01-01

Sexual harassment on college campuses is a frequent occurrence and serious public health concern. Victims of sexual harassment are at risk for many possible negative health consequences. In addition, certain psychological distress symptoms and/or alcohol use may put individuals at increased risk of being victims of sexual harassment. Data from more than 2,000 college students in the Midwestern United States were used to examine reciprocal causal effects of the relations between (a) experiencing sexual harassment and alcohol use and (b) experiencing sexual harassment and psychological distress symptoms, specifically depression and anger/hostility. Analyses were conducted separately for sexual harassment which occurs at school and which occurs in college students' workplaces, and also separately for men and women. Results of cross-lagged panel models showed that there were reciprocal causal effects between sexual harassment and alcohol problems, depression, and anger. Discussion focuses on the overall patterns of results as well as the nuances within these findings.

Data from over 2,000 college students in the Midwestern United States were used to examine reciprocal causal effects of the relations between (1) experiencing sexual harassment and alcohol use and (2) experiencing sexual harassment and psychological distress symptoms, specifically depression and anger/hostility. Analyses were conducted separately for sexual harassment that occurs at school and that occurs in college students’ workplaces and also separately for men and women. Results of cross-lagged panel models showed that there were reciprocal causal effects between sexual harassment and alcohol problems, depression, and anger. Discussion focuses on the overall patterns of results as well as the nuances within these findings. PMID:26983588

Hebephilia refers to a persistent intense sexual interest in pubescent children. Although not as widely studied as pedophilia, studies of hebephilia have indicated convergence in self-report and sexual arousal. The present study expanded on previous work by examining convergent and divergent validity across indicators of hebephilia that included self-report, sexual behavior, and sexual arousal in a sample of 2238 men who had sexually offended. We included men who denied such interest and specifically examined the overlap between hebephilia and pedophilia and examined pedohebephilia (i.e., sexual interests in both prepubescent and pubescent children). Results indicated that there was considerable convergence across indicators of hebephilia. The results suggested poor divergent validity between hebephilia and pedophilia, as there was substantial overlap between the two constructs across analyses. Finally, a distinct pattern of sexual arousal was found in offenders with pedohebephilia. The results of the present study were discussed with a focus on implications for the assessment of sexual interest in children and the conceptualization of pedohebephilia.

Extreme sexual behavior in dementia as a specific manifestation of disinhibition.

2014-01-01

In nursing homes, extreme sexual behavior is one of the most challenging behaviors in dementia. Despite this, however, there is no conformity in the literature regarding how to label and define this type of behavior. Examples of labels used include inappropriate sexual behavior, improper sexual behavior, sexually disinhibited behavior, or hyper sexuality. According to recent theoretical perspectives, extreme sexual behavior may be regarded as a part of disinhibited behavior or could be considered as an independent neuropsychiatric symptom. In this multicenter study, it was investigated whether there is a relationship between extreme sexual behavior and the typical neuropsychiatric symptoms seen in dementia. In 179 residents diagnosed with dementia, extreme sexual behavior was measured using an observation scale. Twelve neuropsychiatric symptoms were measured by the Neuropsychiatric Inventory. Multivariate analysis of covariance with gender showed that residents with observed extreme sexual behavior (n = 43) only showed a higher score on neuropsychiatric symptom 'disinhibition', as compared to residents with non-observed sexual behavior (n = 136). In addition, the effect size was large. These findings indicate that among residents with dementia, extreme sexual behaviors should not be considered as an independent neuropsychiatric symptom. Instead, disinhibition may be an important underlying mechanism for extreme sexual behavior and thus validates the label 'sexually disinhibited behavior'.

Pleasure, Power, and Inequality: Incorporating Sexuality Into Research on Contraceptive Use

PubMed Central

Hirsch, Jennifer S.

2008-01-01

We know surprisingly little about how contraception affects sexual enjoyment and functioning (and vice versa), particularly for women. What do people seek from sex, and how do sexual experiences shape contraceptive use? We draw on qualitative data to make 3 points. First, pleasure varies. Both women and men reported multiple aspects of enjoyment, of which physical pleasure was only one. Second, pleasure matters. Clear links exist between the forms of pleasure respondents seek and their contraceptive practices. Third, pleasure intersects with power and social inequality. Both gender and social class shape sexual preferences and contraceptive use patterns. These findings call for a reframing of behavioral models that explain why people use (or do not use) contraception. PMID:18703457

Psychological profiling of offender characteristics from crime behaviors in serial rape offences.

Kocsis, Richard N; Cooksey, Ray W; Irwin, Harvey J

2002-04-01

Criminal psychological profiling has progressively been incorporated into police procedures despite a dearth of empirical research. Indeed, in the study of serial violent crimes for the purpose of psychological profiling, very few original, quantitative, academically reviewed studies actually exist. This article reports on the analysis of 62 incidents of serial sexual assault. The statistical procedure of multidimensional scaling was employed in the analysis of this data, which in turn produced a five-cluster model of serial rapist behavior. First, a central cluster of behaviors were identified that represent common behaviors to all patterns of serial rape. Second, four distinct outlying patterns were identified as demonstrating distinct offence styles, these being assigned the following descriptive labels brutality, intercourse, chaotic, and ritual. Furthermore, analysis of these patterns also identified distinct offender characteristics that allow for the use of empirically robust offender profiles in future serial rape investigations.

In the present study, the aphrodisiac properties of the purple corn ( Zea mays) in male rats were analyzed. The aqueous crude extract of purple corn (at 25, 50, and 75 mg/kg) was administered to ( a) copulating male rats and ( b) anesthetized and spinal cord transected male rats. Behavioral parameters of copulatory behavior and parameters of the genital motor pattern of ejaculation previous to its inhibition, under the influence of the purple corn extract, are described. Administration of the aqueous crude extract of purple corn significantly facilitates the arousal and execution of male rat sexual behavior without significant influences on the ambulatory behavior. In addition, purple corn extract elicit a significant increase in the number of discharges of the ejaculatory motor patterns and in the total number of genital motor patterns evoked in spinal rats. The present findings show that the aqueous crude extract of purple corn possesses aphrodisiac activity.

Older adults are remaining sexually active for longer periods of time, underscoring the need to assess sexual activity patterns in this group and identify differences by race/ethnicity, some of which may have implications for the development and implementation of sexual risk reduction interventions. Using data from the 2010 National Social Life, Health, and Aging Project, this study examined responses from 1,429 adults aged 60 years and older. Multinomial logistic regression compared sexual behaviors, health-related indicators, interactions with healthcare professionals, and HIV-related perceptions across participants' race/ethnicity. Approximately 81% of participants self-reported as non-Hispanic white, 10.59% as African American, and 8.05% as Hispanic. On average, participants were 69.9 years of age. In the previous year, 49.3% of participants engaged in sexual intercourse; only 3% used condoms. The majority of participants (83.1%) visited a physician at least twice in the previous year, 30.9% had discussed sex with a physician since turning 50, and 14.2% had been tested for HIV. Relative to non-Hispanic whites, African Americans were more likely to be divorced (OR=3.23, P<0.001) or widowed (OR=2.90, P<0.001); have more lifetime sexually transmitted infection (STI) diagnoses (OR=1.67, P=0.030); and have paid for sex (OR=2.83, P=0.002). Although African Americans had greater perceived risk for HIV infection (OR=1.66, P=0.046), they were less likely to have discussed sex with a physician since turning 50 (OR=0.45, P=0.009). Contextualized interventions to improve patient-provider communication and proactive screening behaviors in sexually-active and aging African Americans are needed.

The present meta-analysis studies the relations of pubertal timing and status with sexual behavior and sexual risk behavior among youth aged 10.5-22.4 years. We included biological sex, age, and ethnicity as potential moderators. Four databases were searched for studies (published between 1980 and 2012) on the relation between pubertal timing or status and sexual behavior. The outcomes were (1) sexual intercourse; (2) combined sexual behavior; and (3) risky sexual behavior. Earlier pubertal timing or more advanced pubertal status was related to earlier and more sexual behavior, and earlier pubertal timing was related to more risky sexual behavior. Further, the links between (1) pubertal status and combined sexual behavior and (2) pubertal timing and sexual intercourse status, combined sexual behavior, and risky sexual behavior were stronger for girls than boys. Most links between pubertal status, timing, and sexual behavior and sexual risk behavior were stronger for younger adolescents. Moderation by ethnicity did not yield consistent results. There was significant variation in results among studies that was not fully explained by differences in biological sex, age, and ethnicity. Future research is needed to identify moderators that explain the variation in effects and to design sexual health interventions for young adolescents.

Although sexting among U.S. youth has received much popular media attention, there are only limited data on its prevalence among ethnic minority youth. This study, therefore, specifically examined the prevalence and patterns of sexting (sending and/or receiving a nude or semi-nude picture/video or a sexual text-only message) among a sample of black and Hispanic youth. Data from 1,034 tenth graders from a large, urban school district in southeast Texas were used to calculate the prevalence of sexting by gender-race/ethnicity. Overlap among sexting behaviors was also examined. Electronic surveys were administered via an audio-computer-assisted self-interview on laptop computers. Prevalence estimates were obtained, and chi-square analyses were conducted to compare the distribution of sexting behaviors by gender-race/ethnicity subgroups. More than 20% of students reported sending either a nude or semi-nude picture/video or a sexual text-only message (jointly referred to as a "sext"), and more than 30% reported receiving a sext. Sexts were also frequently shared with unintended recipients. Black males and females reported similar prevalence estimates for sexting behaviors. However, they were more likely than Hispanic males to participate in some sexting behaviors. Hispanic females reported the lowest estimates for sexting behaviors for all gender-race/ethnicity subgroups. Many youth who sent or received a nude or semi-nude picture/video were also likely to have sent or received sexual text-only messages. The results of this study indicate that sexting is prevalent among ethnic minority youth. However, more research is needed to understand the specific context and circumstances around which sexting occurs in this population.

The Developmental Association of Sexual Self-Concept with Sexual Behavior among Adolescent Women

2013-01-01

Developing a sexual self-concept is an important developmental task of adolescence; however, little empirical evidence describes this development, nor how these changes are related to development in sexual behavior. Using longitudinal cohort data from adolescent women, we invoked latent growth curve analysis to: (1) examine reciprocal development in sexual self-concept (sexual openness, sexual esteem and sexual anxiety) over a four year time frame; (2) describe the relationship of these trajectories with changes in sexual behavior. We found significant transactional effects between these dimensions and behavior: sexual self-concept evolved during adolescence in a manner consistent with less reserve, less anxiety and greater personal comfort with sexuality and sexual behavior. Moreover, we found that sexual self-concept results from sexual behavior, as well as regulates future behavior. PMID:20970178

Effective sexual health promotion programs need to be based on evidence; this study describes a set of sexual behavioral patterns, education and other subjects related to sexual life among 71th, 8th and 9th grade students in the State of Lara, Venezuela. During 2003 to 2004 school period, 2070 students filled out the Global School Health Survey (GSHS)--a school based cross-sectional self-administered survey that explores, among other areas, sexual behavior. Students who responded that ever had intercourse, males 27% and females 3.8%; by grade, males 18.2% (7th) and 37.6 % (9th), and females 1.9% (7th) and 6.2% (9th). The group who had intercourse, 54.9% males and 25.3% females had it by age 12; 59% males and 78.6% females were sexually active in the past 12 months; 59.2% males and 43.2% females used condom in the last intercourse; and 48.3% males and 21.5% females has 2 or more sexual partners in their life. A disparity is present in school-based information, >63% for AIDS and <32% for sexual abuse. This study shows that a substantial number of students had sexual intercourse initiation at early age (<12), history of multiple sexual partners and low prevalence of condom use. An unbalanced coverage of information on AIDS and sexual abuse is highly prevalent in the school. However, the implementation and evaluation of comprehensive programs on healthy sexual life must take into account that still a majority of students report abstinence from sexual intercourse.

Men who have sex with men (MSM) are of immediate concern in China's HIV epidemic. In 2008, approximately 2.5-6.5% of China's eight million MSM were HIV positive, while MSM represented 11% of all new HIV cases. Two factors that will in-part determine HIV-transmission dynamics among MSM, are sexual mixing patterns and the social networks which shape them. Sexual mixing patterns and social networks of Chinese MSM, however, remain poorly understood with little refined data available. One reason is that stigma discourages disclosure of names and identifiers to researchers. Using an alternative network-mapping approach, matched case-control design, and snowball sampling, this pilot study sought to compare characteristics of social networks of HIV-positive and HIV-negative Beijing MSM at the individual, dyad, and network levels. First, HIV-negative MSM controls were matched to HIV-positive MSM cases based on age, education, residency, and ethnicity. Then, each case or control and their MSM social network convened at a specific time and location with study investigators. Venues included health clinics, karaoke clubs, brothels, and community centers. Then, using arbitrarily assigned numbers in lieu of actual names, all participants simultaneously completed self-administered surveys regarding their sexual relationships with other participants of the same social network. These new findings indicate that cross-generational sex (anal or oral sex between men with ≥10 years age difference) was more prevalent among social networks of HIV-positive MSM, and was due to older age structure of the social network, rather than behavioral differences in sex-partner selection. Members of social networks of HIV-positive MSM were also less likely to have ever disclosed their MSM identity to non-MSM. Future studies should partner with MSM advocacy groups to explore behavioral and structural interventions as possible means of reducing the cross-generational sex and sexual identity-development issues elevating HIV risk for young Chinese MSM.

Cultural factors affecting urban Mexican male homosexual behavior.

PubMed

Carrier, J M

1976-03-01

Some aspects of the mestizoized urban culture in Mexico are linked to male homosexuality in support of the theory that cultural factors play an important role in the kind of life styles and sex practices of males involved in homosexual behavior. The following factors are considered relevant: the sharp dichotomization of gender roles, dual categorization of females as good or bad, separate social networks maintained by males before and after marriage, proportion of unmarried males, and distribution of income. One result of the sharp dichotomization of male and female gender roles is the widely held belief that effeminate males generally prefer to play the female role rather than the male. Effeminacy and homosexuality are also linked by the belief that as a result of this role preference effeminate males are sexually interested only in masculine males with whom they play the passive sex role. The participation of masculine males in homosexual encounters is related in part to a relatively high level of sexual awareness in combination with the lack of stigmatization of the insertor sex role and in part to the restraints placed on alternative sexual outlets by available income and/or marital status. Males involved in homosexual behavior in Mexico operate in a sociocultural environment which gives rise to expectations that they should play either the insertee or insertor sex role but not both and that they should obtain ultimate sexual satisfaction with anal intercourse rather than fellatio. In spite of cultural imperatives, however, individual preferences stemming from other variables such as personality needs, sexual gratification, desires of wanted partners, and amount of involvement may override the imperatives with resulting variations in sexual behavior patterns.

Psychopathology and personality in juvenile sexual homicide offenders.

Myers, W C; Blashfield, R

1997-01-01

This project describes the psychopathology and personality findings in 14 juveniles who committed sexual homicide. These incarcerated youth were assessed using a structured interview, a personality assessment instrument, correctional files review, and an author-designed clinical interview. Nearly all of these youth met DSM-III-R conduct disorder criteria at the time of the crime. The presence of personality disorders and moderately high psychopathy scores at follow-up were common. Two-thirds of these youth reported the presence of violent sexual fantasies before their crimes. Weapons, most often knives, were used by these juvenile sexual murderers to kill known victims in a majority of the cases. They usually acted alone and selected a low risk victim. These findings suggest that juvenile sexual murderers are an emotionally and behaviorally disturbed population with identifiable psychopathology, personality disturbances, and criminal patterns.

This study explores patterns of drug use and related correlates among a sample of men who have sex with men (MSM) and men who sell sex to other men (aka "money boys") in China. Data were collected from MSM and money boys (MBs) in Shanghai, China using a Community Popular Opinion Leader (CPOL) research design with a self-administered cross-sectional survey to: (1) describe drug use and drug use correlates and (2) examine relationships between drug use and sexual behaviors in general MSM and MBs. The sample consisted of 402 MSM (203 MBs) who live in Shanghai, China. Descriptive statistics and regression analyses were used to explore associations between drug use and sexual behaviors and make comparisons between MBs and general MSM. MBs reported using more drugs in the last week, 3 months and ever; sex after using drugs, and unprotected sex after using drugs more frequently than general MSM. Additionally, many MBs reported receiving free drugs from their clients and those who did receive free drugs were very likely to report having unprotected sex. It is crucial to increase research and include Chinese MSM and their drug use in the Chinese policy conversation. These data suggest that drug use and sexual behaviors after drug use among Chinese MSM differ widely based upon selling sex and separate intervention strategies may be appropriate.

The relationship between risk networks' patterns of crack cocaine and alcohol consumption and HIV-related sexual behaviors among adult injection drug users: a prospective study.

Social context may be an important determinant of drug and alcohol consumption and HIV-related behaviors. To assess the influence of peers on drug users' risk behaviors this study examined the association between individual level and group level behaviors. This analysis reports on the prospective association between baseline self-reported drug and alcohol use of the network members of injection drug users, and self-reported sexual behaviors and alcohol use at 5-month follow-up. Participants were a nontreatment sample of inner-city injection drug users who volunteered for a network-oriented HIV preventive intervention. They were predominantly unemployed, African American males. Of the 71 index participants who completed both the baseline and follow-up interviews, 227 of their drug network members were enrolled in the study. At baseline indexes' sexual risk behaviors were significantly associated with their drug network members' level of crack cocaine use. At follow-up higher levels of alcohol and crack use among drug network members were associated with indexes' reports of multiple sex partners and increased alcohol consumption. Higher levels of crack use among the drug network members were associated with the indexes' reporting casual sex partners at follow-up. These results highlight the importance of studying the role of peer group influence and the social context of risk behaviors.

Socioeconomic disadvantage and adolescent women's sexual and reproductive behavior: the case of five developed countries.

PubMed

Singh, S; Darroch, J E; Frost, J J

2001-01-01

Differences among developed countries in teenagers' patterns of sexual and reproductive behavior may partly reflect differences in the extent of disadvantage. However, to date, this potential contribution has received little attention. Researchers in Canada, France, Great Britain, Sweden and the United States used the most current survey and other data to study adolescent sexual and reproductive behavior. Comparisons were made within and across countries to assess the relationships between these behaviors and factors that may indicate disadvantage. Adolescent childbearing is more likely among women with low levels of income and education than among their better-off peers. Levels of childbearing are also strongly related to race, ethnicity and immigrant status, but these differences vary across countries. Early sexual activity has little association with income, but young women who have little education are more likely to initiate intercourse during adolescence than those who are better educated. Contraceptive use at first intercourse differs substantially according to socioeconomic status in some countries but not in others. Within countries, current contraceptive use does not differ greatly according to economic status, but at each economic level, use is higher in Great Britain than in the United States. Regardless of their socioeconomic status, U.S. women are the most likely to give birth as adolescents. In addition, larger proportions of adolescents are disadvantaged in the United States than in other developed countries. Comparatively widespread disadvantage in the United States helps explain why U.S. teenagers have higher birthrates andpregnancy rates than those in other developed countries. Improving U.S. teenagers' sexual and reproductive behavior requires strategies to reduce the numbers of young people growing up in disadvantaged conditions and to help those who are disadvantaged overcome the obstacles they face.

Differences in Risky Sexual Behavior According to Sexual Orientation in Korean Adolescents.

2017-10-13

Adolescents in sexual minority groups are known to be at risk of contracting sexually transmitted diseases through risky sexual behavior. However, few studies have examined associations between sexual orientation and risky sexual behavior and sexually transmitted diseases in Korean adolescents. Therefore, this cross-sectional study used raw data from the Tenth Korea Youth Risk Behavior Web-Based Survey to explore these relationships. Logistic regression analyses were performed to examine the associations between risky sexual behavior and sexual orientation in adolescents. The participants were 6,884 adolescents who provided data regarding demographic characteristics, sexual orientation, and risky sexual behavior. The proportions of homosexual and bisexual subjects who used condoms, engaged in sexual intercourse after drinking alcohol, and experienced sexually transmitted diseases were higher relative to those of heterosexual subjects. Associations between homosexuality and bisexuality and sexually transmitted diseases and engagement in sexual intercourse after drinking remained after multivariate adjustment. Interventions to prevent risky sexual behavior should target sexual orientation, to improve sexual health and prevent sexually transmitted disease in homosexual and bisexual adolescents.

Compulsive sexual behaviors--difficult aeromedical disposition.

PubMed

Koffman, R L; Berg, J S; Moore, J

1998-10-01

Axis I psychiatric disorders generally are considered incompatible with both the issuance and subsequent maintenance of aeromedical clearance certificates. Little doubt exists as to the impact that conditions such as anxiety disorders, mood disorders, or substance-related disorders have on the conduct of safe flight. Nevertheless, different compulsive sexual behaviors (CSBs), which now are thought to share similar origins and associated comorbidity, can similarly affect impulse control, judgment, concentration, and insight. Yet, these conditions frequently are handled administratively (if not legally). Moreover, in practice CSBs fall within a spectrum of behaviors from "normative" nonparaphilic sexuality to more deviant paraphilic behavior. Through the presentation of five selected cases seen at the Naval Operational Medicine Institute, this article explores examiner difficulty in establishing a diagnosis, discusses models useful in understanding the origins of these disorders, and highlights critical elements in establishing aeromedical disposition. The authors conclude that CSBs may be associated with anxiety, dysphoria, a pattern of increased risk taking, a high threshold for arousal, and poor judgment, which may impact the safety of flight. A comprehensive psychiatric evaluation is essential in determining aeromedical disposition, and consideration should be given to reviewing these cases from a medical perspective prior to any administrative disposition.

Child Sexual Abuse and Negative Affect as Shared Risk Factors for Sexual Aggression and Sexual HIV Risk Behavior in Heterosexual Men.

PubMed

2018-02-01

Previous research has suggested that sexually aggressive behavior and sexual HIV risk behavior are associated. Childhood sexual abuse (CSA) is a well-established risk factor for both types of problematic sexual behavior. Negative affect (i.e., anxiety, depression, and anger) is a less well-studied risk factor, but it has been theorized to relate to both sexual aggression and HIV risk behavior. Thus, this study sought to (1) confirm the relationship between sexual aggression and HIV risk behavior, (2) establish CSA and negative affect as shared risk factors for sexual aggression and HIV risk behavior, and (3) evaluate whether negative affect mediates the relationship between CSA and sexual aggression and between CSA and HIV sexual risk in a sample of heterosexual men. We recruited 18- to 30-year-old heterosexual men (N = 377) from urban sexually transmitted infection clinics. Men completed measures of sexual HIV risk history (number of partners and condom use), sexual aggression history, CSA history, and trait negative affect (anger, anxiety, and depression). Structural equation modeling was used to examine hypothesized direct and indirect relationships. In the final SEM model, sexual aggression history and sexual HIV risk behavior were correlated. CSA was associated with both types of problematic sexual behavior. Anxiety significantly mediated the relationship between CSA and sexual aggression and between CSA and sexual HIV risk behavior (χ 2 [1300] = 2121.79, p < .001; CFI = 0.905; RMSEA [90% CI] = .044 [.041-.047]). Sexual aggression appears to be part of a constellation of sexual risk behaviors; thus, it may be possible to develop prevention programs that target both sexual HIV risk and sexual aggression. CSA is a shared risk factor for sexual aggression and HIV risk behavior through the pathway of anxiety. Thus, anxiety might be one promising target for intervention.

Sexual compulsivity, state affect, and sexual risk behavior in a daily diary study of gay and bisexual men.

2010-09-01

Researchers have identified a strong link between sexual compulsivity (SC) and risky sexual behavior among men who have sex with men (MSM). Meanwhile, affect/mood has also been connected with negative sexual health outcomes (sexually transmitted infection/human immunodeficiency virus [HIV] transmission, sexual risk, sex under the influence of drugs/alcohol). Given that SC is characterized by marked distress around one's own sexual behavior, affect may play a central role in SC and HIV risk behavior. Data were taken from the Pillow Talk Project, a pilot study conducted in 2008-2009 with 50 highly sexually active MSM (9 or more male sex partners, ≤ 90 days), of which half displayed SC symptoms and half did not. Forty-seven men completed a daily diary online for 30 days (n = 1,060 diary days), reporting on their sexual behavior and concurrent affect: positive activation, negative activation, anxious arousal, and sexual activation. We conducted HLM analyses using daily affect (Level 1, within subjects) and SC and HIV status (Level 2, between subjects) to predict sexual behavior outcomes. Increased negative activation (characterized by fear, sadness, anger, and disgust) was associated with reduced sexual risk behavior, but less so among sexually compulsive MSM. Sexual activation was associated with increased sexual risk taking, but less so among sexually compulsive MSM. Anxious arousal was associated with increased sexual behavior, but not necessarily sexual risk taking. Findings indicate that affect plays key roles in sexual behavior and sexual risk taking; however, the association between affect and behavior may be different for sexually compulsive and non-sexually compulsive MSM.

Buffer or Brake? The Role of Sexuality-Specific Parenting in Adolescents' Sexualized Media Consumption and Sexual Development.

Overbeek, Geertjan; van de Bongardt, Daphne; Baams, Laura

2018-03-13

One main source of sexual socialization lies within family interactions. Especially sexuality-specific parenting may determine adolescents' sexual development-adolescents' sexual behavior and sexual risk behavior, sexualized media consumption and permissive sexual attitudes-to a significant extent, but different ideas exist about how this works. In this longitudinal study, we examined two hypotheses on how sexuality-specific parenting-parenting aimed specifically at children's sexual attitudes and behaviors-relates to adolescents' sexual development. A first buffer hypothesis states that parents' instructive media discussions with their children-called instructive mediation-buffers the effect of sexualized media consumption on adolescents' sexual attitudes and behavior and, vice versa, the effect of adolescents' sexual attitudes and behavior on sexualized media consumption. A second brake hypothesis states that parents, by communicating love-and-respect oriented sexual norms, slow down adolescents' development toward increased sexualized media use, permissive sexual attitudes, and sexual behavior and sexual risk behavior. Using four-wave longitudinal data from 514 Dutch adolescents aged 13-16 years (49.8% female), we found evidence to support a brake effect. More frequent parental communication of love-and-respect oriented sexual norms was associated with less permissive sexual attitudes and, for boys, with less advanced sexual behavior and a less rapid increase in sexual risk behavior. Parents' instructive mediation regarding adolescents' sexualized media consumption was associated with less permissive sexual attitudes at baseline, but only for girls. No systematic evidence emerged for a buffer effect of parents' instructive mediation. In conclusion, although our data seem to suggest that parent-child communication about sex is oftentimes "after the fact", we also find that more directive parental communication that conveys love-and-respect oriented sexual norms brake adolescents' move toward sexual maturity.

Developing a sexual self-concept is an important developmental task of adolescence; however, little empirical evidence describes this development, nor how these changes are related to development in sexual behavior. Using longitudinal cohort data from adolescent women, we invoked latent growth curve analysis to: (1) examine reciprocal development in sexual self-concept (sexual openness, sexual esteem and sexual anxiety) over a four year time frame; (2) describe the relationship of these trajectories with changes in sexual behavior. We found significant transactional effects between these dimensions and behavior: sexual self-concept evolved during adolescence in a manner consistent with less reserve, less anxiety and greater personal comfort with sexuality and sexual behavior. Moreover, we found that sexual self-concept results from sexual behavior, as well as regulates future behavior. Copyright © 2010 The Foundation for Professionals in Services for Adolescents.

Several smartphone applications (apps) designed to help men who have sex with men (MSM) find casual sexual partners have appeared on the market recently. Apps of this nature have the potential to impact sexual health and behavior by providing constant access to a large supply of available partners. In this study, the sexual health history, behavior, and personality of MSM who use these apps was compared to MSM who meet partners in other ways. A sample of 110 adult MSM was recruited online to complete a cross-sectional survey. All participants were either single or involved in a non-exclusive romantic relationship. There were no statistically significant differences between app users and non-users in frequency of insertive or receptive anal sex without a condom. However, app users reported significantly more sexual partners and had a higher prevalence of ever being diagnosed with an STI than did non-users. App users did not differ from non-users on any demographic or personality variables (including erotophilia, sensation seeking, and self-control); however, when adjusting lifetime total sex partners for those met specifically through apps, app users still had significantly more partners. This pattern of results suggests that app users may be more sexually active in general. More work is needed to fully understand the association between this emerging technology and potential sexual health risks.

Seasonal Effects on the Population, Morphology and Reproductive Behavior of Narnia femorata (Hemiptera: Coreidae).

Many insects are influenced by the phenology of their host plants. In North Central Florida, Narnia femorata (Hemiptera: Coreidae) spends its entire life cycle living and feeding on Opuntia mesacantha ssp. lata . This cactus begins producing flower buds in April that lead to unripe green fruit in June that ripen into red fruit through December. Many morphological and behavioral characteristics of N. femorata are known to be affected by cactus phenology in a controlled laboratory setting, including the degree of sexual dimorphism and mating behavior. Our goal with this study was to determine if similar phenotypic changes of N. femorata occurred over time in the wild, and the extent to which these changes were concordant with phenological changes in its host plant. Further, we investigate the length of the insect mouthparts (beak) over time. Ongoing work has suggested that beak length may change across cohorts of developing insects in response to feeding deep within cactus fruit where seed and pulp depth decrease as the fruit ripens. Our results revealed a drop in cactus fruit abundance between the months of July through October 2015 as cactus fruits turned red and ripened. Simultaneously, the average body size of both males and females of N. femorata declined at two sampled sites. Male hind femora (a sexually-selected weapon) decreased disproportionately in size over time so that males later in the year had relatively smaller hind femora for their body size. The sex-specific patterns of morphological change led to increased sexual-size dimorphism and decreased sexual dimorphism for hind femora later in the year. Further, we found that beak length decreased across cohorts of insects as cactus fruit ripened, suggesting phenotypic plasticity in mouthpart length. Behavioral studies revealed that female readiness to mate increased as the season progressed. In sum, we found pronounced changes in the phenotypes of these insects in the field. Although this study is far from comprehensive, it provides tantalizing patterns that suggest many directions for future research.

Sexual behaviors in children: evaluation and management.

PubMed

Kellogg, Nancy D

2010-11-15

Sexual behaviors in children are common, occurring in 42 to 73 percent of children by the time they reach 13 years of age. Developmentally appropriate behavior that is common and frequently observed in children includes trying to view another person's genitals or breasts, standing too close to other persons, and touching their own genitals. Sexual behaviors become less common, less frequent, or more covert after five years of age. Sexual behavior problems are defined as developmentally inappropriate or intrusive sexual acts that typically involve coercion or distress. Such behaviors should be evaluated within the context of other emotional and behavior disorders, socialization difficulties, and family dysfunction, including violence, abuse, and neglect. Although many children with sexual behavior problems have a history of sexual abuse, most children who have been sexually abused do not develop sexual behavior problems. Children who have been sexually abused at a younger age, who have been abused by a family member, or whose abuse involved penetration are at greater risk of developing sexual behavior problems. Although age-appropriate behaviors are managed primarily through reassurance and education of the parent about appropriate behavior redirection, sexual behavior problems often require further assessment and may necessitate a referral to child protective services for suspected abuse or neglect.

Individual-Based Compulsive Sexual Behavior Scale: Its Development and Importance in Examining Compulsive Sexual Behavior.

PubMed

Efrati, Yaniv; Mikulincer, Mario

2018-04-03

Compulsive sexual behavior comprises individual-based (e.g., sexual fantasies, compulsive sexual thoughts, masturbation) and partnered (e.g., interpersonal sexual conquests, repeated infidelity) facets. Most instruments for assessing compulsive sexual behavior, however, focus less on the individual-based facet and specifically on fantasies and compulsive thoughts. In the current research, we developed and validated an individual-based compulsive sexual behavior scale (I-CSB). In Study 1 (N = 492), the factorial structure of the I-CSB was examined. In Study 2 (N = 406), we assessed I-CSB's convergent validity. In Study 3 (N = 112), we examined whether the I-CSB differentiates between individuals who suffer from compulsive sexual behavior and those who do not. Results revealed a four-factor structure for individual-based compulsive sexual behavior that is associated with an intense inner conflict regarding sexuality (high arousal contrasting with high sexual anxiety), and that accounts for approximately 75% of the differences between people with compulsive sexual behavior and controls. Results are discussed in light of the need for a broader understanding of compulsive sexual behavior.

While the effects of sexually explicit media (SEM) on heterosexuals' sexual intentions and behaviors have been studied, little is known about the consumption and possible influence of SEM among men who have sex with men (MSM). Importantly, conceptual models of how Internet-based SEM influences behavior are lacking. Seventy-nine MSM participated in online focus groups about their SEM viewing preferences and sexual behavior. Twenty-three participants reported recent exposure to a new behavior via SEM. Whether participants modified their sexual intentions and/or engaged in the new behavior depended on three factors: arousal when imagining the behavior, pleasure when attempting the behavior, and trust between sex partners. Based on MSM's experience, we advance a model of how viewing a new sexual behavior in SEM influences sexual intentions and behaviors. The model includes five paths. Three paths result in the maintenance of sexual intentions and behaviors. One path results in a modification of sexual intentions while maintaining previous sexual behaviors, and one path results in a modification of both sexual intentions and behaviors. With this model, researchers have a framework to test associations between SEM consumption and sexual intentions and behavior, and public health programs have a framework to conceptualize SEM-based HIV/STI prevention programs.

Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse linked to suicidal ideation and attempts: findings from the 2006 Korean Youth Risk Behavior Survey.

This study examined the association between early initiation of problem behaviors (alcohol drinking, cigarette smoking, and sexual intercourse) and suicidal behaviors (suicidal ideation and suicide attempts), and explored the effect of concurrent participation in these problem behaviors on suicidal behaviors among Korean adolescent males and females. Data were obtained from the 2006 Korean Youth Risk Behavior Survey, a nationally representative sample of middle and high school students (32,417 males and 31,467 females) in grades seven through twelve. Bivariate and multivariate logistic analyses were conducted. Several important covariates, such as age, family living structure, household economic status, academic performance, current alcohol drinking, current cigarette smoking, current butane gas or glue sniffing, perceived body weight, unhealthy weight control behaviors, subjective sleep evaluation, and depressed mood were included in the analyses. Both male and female preteen initiators of each problem behavior were at greater risk for suicidal behaviors than non-initiators, even after controlling for covariates. More numerous concurrent problematic behaviors were correlated with greater likelihood of seriously considering or attempting suicide among both males and females. This pattern was more clearly observed in preteen than in teen initiators although the former and latter were engaged in the same frequency of problem behavior. Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors.

Dopamine release in the medial preoptic area is related to hormonal action and sexual motivation.

Kleitz-Nelson, Hayley K; Dominguez, Juan M; Ball, Gregory F

2010-12-01

To help elucidate how general the role of dopamine (DA) release in the medial preoptic area (mPOA) is for the activation of male sexual behavior in vertebrates, we recently developed an in vivo microdialysis procedure in the mPOA of Japanese quail. Using these techniques in the present experiment, the temporal pattern of DA release in relation to the precopulatory exposure to a female and to the expression of both appetitive and consummatory aspects of male sexual behavior was investigated. Extracellular samples from the mPOA of adult sexually experienced male quail were collected every 6 min before, while viewing, while in physical contact with, and after exposure to a female. In the absence of a precopulatory rise in DA, males failed to copulate when the barrier separating them from the female was removed. In contrast, males that showed a substantial increase in mPOA DA during precopulatory interactions behind the barrier, copulated with females after its removal. However, there was no difference in DA during periods when the quail were copulating as compared to when the female was present but the males were not copulating. In addition, we show that precopulatory DA predicts future DA levels and copulatory behavior frequency. Furthermore, the size of the cloacal gland, an accurate indicator of testosterone action, is positively correlated with precopulatory DA. Taken together, these results provide further support for the hypothesis that DA action in the mPOA is specifically linked to sexual motivation as compared to copulatory behavior per se. © 2010 APA, all rights reserved.

The impact of AIDS on an urban population of high-risk female minority adolescents: implications for intervention.

Overby, K J; Kegeles, S M

1994-05-01

This study's purpose was to describe acquired immunodeficiency syndrome (AIDS)-related concerns, risk behaviors, and psychosocial/situational determinants of condom use among an urban minority population of sexually active, adolescent girls. In addition we sought to define the accuracy of personal AIDS risk-assessment, the relative importance of AIDS in relation to other concerns, and the broader context of sexual experience and attitudes in this population. A cross-sectional interview study was conducted involving sexually active female adolescents attending a pediatric clinic in an inner-city university-affiliated community hospital. Sixty-nine subjects (ages 13-19 yr, 90% African-American) were enrolled. While the goals of this study were primarily descriptive, subject characteristics felt to impact on condom use were identified prior to data collection and were examined against several measures of usage including: use at the time of last sexual intercourse, overall frequency of condom use, and reported behavior change to include initiation of or increased condom usage. Forty-one percent of participants reported knowing someone with AIDS. Global concern regarding this disease was high, although worry about poverty-related issues was often greater. Despite concern and high measures of AIDS risk (median number of sex partners, 3; past sexually transmitted disease, 55%; past pregnancy 77%), most participants perceived themselves to be at low personal risk owing to current monogamy, lack of intravenous drug use, and implicit trust in their partner's safety. Discussion with their partner about actual risk and awareness of the importance of past behaviors was generally lacking. Although 98% were aware that condoms may prevent AIDS, 64% used condoms half of the time or less when they had sex and use appeared to be primarily for contraception. Several intrinsic cognitive/psychological and extrinsic social/situational factors were found to correlate with measures of condom use. Participants' sexual histories and behavior emphasize the need for concern regarding AIDS risk in this population. Patterns of sexual behavior and beliefs regarding committed relationships raise challenging questions regarding how to motivate sexually active members of this population to use condoms more frequently. Programs aimed at AIDS prevention among urban minority adolescents need to be cognizant of the larger personal and sociocultural context in which these teenagers are making health-behavior choices.

We studied the effect of sexual excitation on serum testosterone and nitric oxide (NO) levels in water buffalo bulls with different categories of sexual behavior and their correlation with each other. Buffalo bulls were classified according to their sexual behavior (including reaction time, sexual aggressiveness and mating ability): acceptable (good to excellent) (n=5), fair (n=5), and unacceptable (poor) (n=5) sexual behavior. Blood samples were collected from all animals immediately before and after sexual teasing and/or mounting to estimate the testosterone and NO levels using a commercial radioimmunoassay kit and Griess reaction test, respectively. Comparisons among groups were evaluated using a mixed-design analysis of variance. Pearson's correlation coefficients were calculated to determine the relationship between testosterone and NO levels before and after sexual excitation besides sexual behavior. The level of testosterone before sexual excitation was higher (p≤0.05) in bulls with acceptable and fair sexual behavior than in bulls with unacceptable sexual behavior (0.86±0.01, 0.69±0.02, and 0.29±0.02ng/mL, respectively). The level of NO was higher (p≤0.05) in bulls with acceptable and fair sexual behavior than in bulls with unacceptable sexual behavior (8.00±0.03, 7.66±0.19, and 6.29±0.33μM, respectively). Sexual excitation significantly (p<0.05) increase testosterone and NO levels in bulls with acceptable (1.45±0.01ng/mL and 19.04±0.32μM, respectively) or fair (0.92±0.02ng/mL and 14.95±0.34μM, respectively) sexual behavior, but not in bulls with unacceptable sexual behavior. The unacceptable sexual behavior bulls had significantly lower testosterone and NO levels than the other bulls. There was a strong correlation and association between serum testosterone and NO levels besides sexual behavior of buffalo bulls. In conclusion, the alteration in the testosterone and NO levels after sexual excitation depends on the sexual behavior category of buffalo-bull. Testosterone and NO can be used to create a sexual behavior score. The testosterone and NO levels of can be predicted via evaluation of sexual behavior of buffalo bull. Copyright © 2017 Elsevier B.V.

In the bordeline personality disorder (BPD) a large role ascribe to psychological and psychosocial factors. Studies have shown that more than 70% patients BPD reported experiencing traumatic events in childhood. These people compare with patients with other psychiatric disorders often report history of sexual abuse and experience of violence or neglect. Making self-harming can be a reaction to negative experiences in childhood. The findings are confirming that making self-harming is a frequent symptom of BPD and 70-75% patients show at least one act self-harming. Moreover a lowered tolerance level is characteristic of them to the stress and determined course learning dysfunctional patterns of behavior. The aim of this study is to determine the childhood trauma such as sexual, psychological and physical abuse, emotional and physical neglect and to investigate their relation to stress, self-harming and suicidal behavior. In study participated 41 persons with emotionally unstable borderline personality diagnosis. In the group was 32 women and 9 men in age 19-43. The Polish adaptation of standardized questionnaires was used to measure childhood trauma (CTQ), stress (SSI-K), self-injurious behavior (SHI) and suicidal tendencies (RFL-I). In patients with BPD the level of childhood trauma and stress are predictors of self-harming behavior and suicidal tendencies. The mediation analyze showed, that self-harming was an important mediator between sexual abuse and suicidal tendencies. The high stress is the next mediator between sexual abuse and the level of self-harming behavior. A high level of childhood trauma correlates positively with stress, self-harming and suicidal behavior in patients with BPD.

It's All in the Mix: Blend-Specific Behavioral Response to a Sexual Pheromone in a Butterfly

Among insects, sexual pheromones are typically mixtures of two to several components, all of which are generally required to elicit a behavioral response. Here we show for the first time that a complete blend of sexual pheromone components is needed to elicit a response also in a butterfly. Males of the Green-veined White, Pieris napi, emit an aphrodisiac pheromone, citral, from wing glands. This pheromone is requisite for females to accept mating with a courting male. Citral is a mixture of the two geometric isomers geranial (E-isomer) and neral (Z-isomer) in an approximate 1:1 ratio. We found that both these compounds are required to elicit acceptance behavior, which indicates synergistic interaction between processing of the isomers. Using functional Ca2+ imaging we found that geranial and neral evoke significantly different but overlapping glomerular activity patterns in the antennal lobe, which suggests receptors with different affinity for the two isomers. However, these glomeruli were intermingled with glomeruli responding to, for example, plant-related compounds, i.e., no distinct subpopulation of pheromone-responding glomeruli as in moths and other insects. In addition, these glomeruli showed lower specificity than pheromone-activated glomeruli in moths. We could, however, not detect any mixture interactions among four identified glomeruli, indicating that the synergistic effect may be generated at a higher processing level. Furthermore, correlations between glomerular activity patterns evoked by the single isomers and the blend did not change over time. PMID:26973536

Vaginismus and dyspareunia: relationship with general and sex-related moral standards.

2011-01-01

Relatively strong adherence to conservative values and/or relatively strict sex-related moral standards logically restricts the sexual repertoire and will lower the threshold for experiencing negative emotions in a sexual context. In turn, this may generate withdrawal and avoidance behavior, which is at the nucleus of vaginismus. To examine whether indeed strong adherence to conservative morals and/or strict sexual standards may be involved in vaginismus. The Schwartz Value Survey (SVS) to investigate the individual's value pattern and the Sexual Disgust Questionnaire (SDQ) to index the willingness to perform certain sexual activities as an indirect measure of sex-related moral standards. The SVS and SDQ were completed by three groups: women diagnosed with vaginismus (N=24), a group of women diagnosed with dyspareunia (N=24), and a healthy control group of women without sexual complaints (N=32). Specifically, the vaginismus group showed relatively low scores on liberal values together with comparatively high scores on conservative values. Additionally, the vaginismus group was more restricted in their readiness to perform particular sex-related behaviors than the control group. The dyspareunia group, on both the SVS and the SDQ, placed between the vaginismus and the control group, but not significantly different than either of the groups. The findings are consistent with the view that low liberal and high conservative values, along with restricted sexual standards, are involved in the development/maintenance of vaginismus. © 2010 International Society for Sexual Medicine.

Purpose Increasing attention to the health of lesbian, gay, and bisexual (LGB) populations comes with requisite circumspection about measuring sexual orientation in surveys. However, operationalizing these variables also requires considerable thought. This research sought to document the consequences of different operational definitions of sexual orientation by examining variation in health risk behaviors. Methods Using Massachusetts Youth Risk Behavior Survey data, we examined how operational definitions of sexual behavior and sexual identity influenced differences among three health behaviors known to disparately affect LGB populations: smoking, suicide risk, and methamphetamine use. Sexual behavior and sexual identity were also examined together to explore if they captured unique sources of variability in behavior. Results Estimates of health disparities changed as a result of using either sexual behavior or sexual identity. Youth who reported their sexual identity as “not sure” also had increased odds of health risk behavior. Disaggregating bisexual identity and behavior from same-sex identity and behavior frequently resulted in the attenuation or elimination of health disparities that would have otherwise been attributable to exclusively same-sex sexual minorities. Finally, sexual behavior and sexual identity explained unique and significant sources of variability in all three health behaviors. Conclusion Researchers using different operational definitions of sexual orientation could draw different conclusions, even when analyzing the same data, depending upon how they chose to represent sexual orientation in analyses. We discuss implications that these manipulations have on data interpretation and provide specific recommendations for best-practices when analyzing sexual orientation data collected from adolescent populations.

The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups. This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai. From a total 1215 participants, 487 (40.1%) were lowland Thai and 728 (59.9%) were from ethnic minorities. Overall, 17.9% of respondents reported "ever had sex." Lowland Thai adolescents were more likely to have ever had sex compared with ethnic minority adolescents (AOR, 1.61; CI, 1.06-2.45; P< 0.01). A higher proportion of lowland Thai respondents reported having ≥ 2 lifetime sexual partners (51.9% vs. 33.3%, P = 0.003), or currently having a boy/girlfriend (59.9% vs. 45.3%, P< 0.001) compared to ethnic minority adolescents. Consistent condom use was low in both groups (22.6%). The common significant factors associated with "ever had sex" in both groups were "ever drunk alcohol in the past year" and "currently having a boy/girlfriend." Specifically, for lowland Thai youth, being around the age of 17 or 18 years and "ever used methamphetamine in the past year" were associated with increased odds of "ever had sex". For ethnic minority adolescents, being female and belonging to religions other than Buddhism were associated with decreased odds of "ever had sex". A substantially higher proportion of lowland Thai engage in risky sexual behaviors when compared to ethnic minorities. However, both groups remained vulnerable to HIV and other sexually transmitted infections. To minimize sexual risks, education program and school-based interventions are warranted to increase awareness of young people about risky behaviors and to promote essential life skills.

Sexual Preoccupation Behavior in Parkinson's Disease.

People with Parkinson's disease (PD) present with problematic sexual behaviors that are often misunderstood or ignored. Sexual problems in PD are part of a non-motor syndrome, and they play a  prominent role in the life of affected individuals and their partners. Based on our considerable clinical experience, we describe four common types of sexual preoccupation behaviors in people with PD: (1) sexual behavior with underlying sexual dysfunction, (2) sexual desire discrepancy with partner after restored desire, (3) hypersexuality and compulsive sexual behavior, and (4) sexual behavior with underlying restless genital syndrome. We also suggest methods of assessing and diagnosing these sexual behaviors, and propose alternative possible treatments for people with PD and their partners/caregivers. Understanding these four behavioral types will assist healthcare professionals in explaining and educating people with PD and their partners, contribute to decreased stress and tension between them, and help them manage these sexual issues.

The Dual Role of Media Internalization in Adolescent Sexual Behavior.

PubMed

Rousseau, Ann; Beyens, Ine; Eggermont, Steven; Vandenbosch, Laura

2017-08-01

Sexualizing media content is prevalent in various media types. Sexualizing media messages and portrayals emphasize unattainable body and appearance ideals as the primary components of sexual desirability. The internalization of these ideals is positively related to self-objectification and sexual body consciousness. In turn, self-objectification and sexual body consciousness affect adolescents' sexual behavior, albeit in opposing directions. While objectifying self-perceptions are linked to higher levels of sexual behavior, body consciousness during physical intimacy is linked to lower levels of sexual behavior. Based on this knowledge, the present three-wave panel study of 824 Belgian, predominant heterosexual adolescents (M age  = 15.33; SD = 1.45) proposes a dual-pathway model that investigates two different pathways through which the internalization of media ideals may impact adolescents' sexual behavior. An inhibitory pathway links media internalization to lower levels of sexual behavior through sexual body consciousness, and a supportive pathway links media internalization to higher levels of sexual behavior through self-objectification. Structural equation analyses supported the proposed dual-pathway, showing that the impact of media internalization on adolescents' sexual behavior proceeds through an inhibitory pathway and a supportive pathway. Regarding the supportive pathway, media internalization (W1) positively predicted sexual behavior (W3), through valuing appearance over competence (W2). Regarding the inhibitory pathway, media internalization (W1) positively predicted body surveillance, which, in turn, positively predicted sexual body consciousness (all W2). Sexual body consciousness (W2) is negatively related to sexual behavior (W3). From a sexual developmental perspective, these findings emphasize the importance of guiding adolescents in interpreting and processing sexualizing media messages.

The influence of media portrayals of sexual attitudes and normative expectations of young people at a critical developmental stage is of public health concern. To examine the role of mass media and Internet utilization in shaping the sexual health attitudes and behaviors of young undergraduates in Osogbo metropolis, Osun State, Nigeria. In a descriptive cross-sectional study, 400 undergraduates were selected using a multistage random sampling technique. Four hundred and fifty pretested, semistructured questionnaires were distributed; of these, 400 were returned properly filled. Data were analyzed using SPSS statistical software version 16. Mean age of respondents ± standard deviation was 23.6±2.99 years. Most were aware of the various forms of mass media (>95%). Most (64.0%) respondents spent 1-5 hours watching television, daily, and most used the Internet often. About 38.3% and 24.2% of respondents used the Internet and radio/television, respectively, as sources of information on sexual issues. Most respondents used the Internet for school assignments (83.0%, n=332), electronic mail (89.0%, n=356), and for accessing sexually explicit materials (74.5%, n=298). Most of the respondents (73.5%) opined that the Internet has a bad influence on youths' sexual behavior, although accessing the Internet for sexual material or movies was acceptable to 25.3% of them. Of the 226 respondents who had ever had sex, 226 (100%), 37 (16.4%), 31 (13.7%), and 10 (4.4%) practiced coitus, oral sex, masturbation, and anal sex, respectively; 122 (54.0%) always used condoms, whereas 90 (40.0%) never used condoms during sexual activity; 33 (14.6%) had had sex with commercial sex workers. Further analysis showed that those who were yet to marry (single) were less likely to be sexually experienced than those who were married (adjusted odds ratio [AOR] =0.075, 95% confidence interval [CI] =0.008-0.679), and those who said accessing the Internet for sexual material is not acceptable to them were also less likely to be sexually experienced than those to whom it was acceptable (AOR =0.043, 95% CI =0.016-0.122). Predictors of having multiple sexual partners include the sex of the respondent and the frequency of Internet use, with females (AOR =0.308, 95% CI =0.113-0.843) and those who rarely use the Internet less likely to have multiple sexual partners. We conclude that uncontrolled exposure to mass media and Internet could negatively influence the sexual patterns and behavior of youths.

Autism spectrum disorders are characterized by impaired social and communicative skills and repetitive behaviors. Emerging evidence supported the hypothesis that these neurodevelopmental disorders may result from a combination of genetic susceptibility and exposure to environmental toxins in early developmental phases. This study assessed the effects of prenatal exposure to chlorpyrifos (CPF), a widely diffused organophosphate insecticide endowed with developmental neurotoxicity at sub-toxic doses, in the BTBR T+tf/J mouse strain, a validated model of idiopathic autism that displays several behavioral traits relevant to the autism spectrum. To this aim, pregnant BTBR mice were administered from gestational day 14 to 17 with either vehicle or CPF at a dose of 6 mg/kg/bw by oral gavages. Offspring of both sexes underwent assessment of early developmental milestones, including somatic growth, motor behavior and ultrasound vocalization. To evaluate the potential long-term effects of CPF, two different social behavior patterns typically altered in the BTBR strain (free social interaction with a same-sex companion in females, or interaction with a sexually receptive female in males) were also examined in the two sexes at adulthood. Our findings indicate significant effects of CPF on somatic growth and neonatal motor patterns. CPF treated pups showed reduced weight gain, delayed motor maturation (i.e., persistency of immature patterns such as pivoting at the expenses of coordinated locomotion) and a trend to enhanced ultrasound vocalization. At adulthood, CPF associated alterations were found in males only: the altered pattern of investigation of a sexual partner, previously described in BTBR mice, was enhanced in CPF males, and associated to increased ultrasonic vocalization rate. These findings strengthen the need of future studies to evaluate the role of environmental chemicals in the etiology of neurodevelopment disorders.

While the effects of sexually explicit media (SEM) on heterosexuals’ sexual intentions and behaviors have been studied, little is known about the consumption and possible influence of SEM among men who have sex with men (MSM). Importantly, conceptual models of how Internet-based SEM influences behavior are lacking. Seventy-nine MSM participated in online focus groups about their SEM viewing preferences and sexual behavior. Twenty-three participants reported recent exposure to a new behavior via SEM. Whether participants modified their sexual intentions and/or engaged in the new behavior depended on three factors: arousal when imagining the behavior, pleasure when attempting the behavior, and trust between sex partners. Based on MSM’s experience, we advance a model of how viewing a new sexual behavior in SEM influences sexual intentions and behaviors. The model includes five paths. Three paths result in the maintenance of sexual intentions and behaviors. One path results in a modification of sexual intentions while maintaining previous sexual behaviors, and one path results in a modification of both sexual intentions and behaviors. With this model, researchers have a framework to test associations between SEM consumption and sexual intentions and behavior, and public health programs have a framework to conceptualize SEM-based HIV/STI prevention programs.

Phylogenetic patterns and phenotypic plasticity of molluscan sexual systems.

Collin, Rachel

Molluscs show a wide diversity of sexual systems and strategies. There are both gastropod and bivalve families that are each primarily dioecious, simultaneous hermaphrodites, or sequential hermaphrodites, and other families in which almost every sexual strategy occurs. The multiple evolutionary transitions of sexual systems within molluscs would allow comparative analyses of the associated ecological factors, but data on all but a few groups are too sparse to draw many solid conclusions. The phylogenetic distribution of sexual systems in the Mollusca shows that gastropods and bivalves demonstrate different patterns, possibly associated with the presence/absence of copulation. The distribution of change of sex suggests that, in gastropods, sequential hermaphrodites do not evolve from simultaneous hermaphrodites, and that sex reversal (flip-flopping) occurs in free-spawners but not in copulators. Three well-studied protandrous gastropod groups (calyptraeids, coralliophilids, and patellogastropods) show similar responses to environmental conditions and associations with conspecifics. They all have the following attributes: (1) they are sedentary, (2) they live in groups, patches, or aggregates, and (3) size at sex change varies among sites and among aggregates. In addition the available experimental evidence suggests that (4) the presence of females or large individuals represses growth and sex change of males, and (5) behavior seems to mediate the repressive influence of large females. Available data from other species tend to support these patterns. Finally, the repression of growth of males by females in protandry likely facilitates the evolution of dwarf males.

Review: neuroestrogen regulation of socio-sexual behavior of males.

PubMed

Ubuka, Takayoshi; Tsutsui, Kazuyoshi

It is thought that estrogen (neuroestrogen) synthesized by the action of aromatase in the brain from testosterone activates male socio-sexual behaviors, such as aggression and sexual behavior in birds. We recently found that gonadotropin-inhibitory hormone (GnIH), a hypothalamic neuropeptide, inhibits socio-sexual behaviors of male quail by directly activating aromatase and increasing neuroestrogen synthesis in the preoptic area (POA). The POA is thought to be the most critical site of aromatization and neuroestrogen action for the regulation of socio-sexual behavior of male birds. We concluded that GnIH inhibits socio-sexual behaviors of male quail by increasing neuroestrogen concentration beyond its optimal concentration in the brain for expression of socio-sexual behavior. On the other hand, it has been reported that dopamine and glutamate, which stimulate male socio-sexual behavior in birds and mammals, inhibit the activity of aromatase in the POA. Multiple studies also report that the activity of aromatase or neuroestrogen is negatively correlated with changes in male socio-sexual behavior in fish, birds, and mammals including humans. Here, we review previous studies that investigated the role of neuroestrogen in the regulation of male socio-sexual behavior and reconsider the hypothesis that neuroestrogen activates male socio-sexual behavior in vertebrates. It is considered that basal concentration of neuroestrogen is required for the maintenance of male socio-sexual behavior but higher concentration of neuroestrogen may inhibit male socio-sexual behavior.

Thigpen, Jeffry W

2009-01-01

This study describes the sexual behavior of 2- to 12-year-old African American children without known histories of sexual abuse and explores the relation of this behavior to gender and age. Primary caregivers were recruited from a public "Well Child" clinic and administered the Child Sexual Behavior Inventory (CSBI), a parental report measure that assesses a broad range of childhood sexual behaviors within 9 specific domains. CSBI data were collected on 249 African American children. Results indicate that African American children display a broad range of sexual behavior that was not reported to frequently occur. Sexual behaviors that involved requesting, planning, or forcing other children and adults into sexual activity were not reported. Although significant differences were not found between frequency levels of sexual behavior reported for boys and girls, the range of sexual behavior observed and reported for girls was narrower in comparison to boys. Significant differences were found between frequency levels of sexual behavior observed and reported for children of different ages. Analysis of the behavioral differences found between children of different ages indicates the emergence of a marked interest in sexuality as African American children approached puberty.

CONTEXT Considerable research has examined reciprocal relationships between parenting, peers and adolescent problem behavior; however, such studies have largely considered the influence of peers and parents separately. It is important to examine simultaneously the relationships between parental monitoring, peer risk involvement and adolescent sexual risk behavior, and whether increases in peer risk involvement and changes in parental monitoring longitudinally predict adolescent sexual risk behavior. METHODS Four waves of sexual behavior data were collected between 2008/2009 and 2011 from high school students aged 13–17 in the Bahamas. Structural equation and latent growth curve modeling were used to examine reciprocal relationships between parental monitoring, perceived peer risk involvement and adolescent sexual risk behavior. RESULTS For both male and female youth, greater perceived peer risk involvement predicted higher sexual risk behavior index scores, and greater parental monitoring predicted lower scores. Reciprocal relationships were found between parental monitoring and sexual risk behavior for males and between perceived peer risk involvement and sexual risk behavior for females. For males, greater sexual risk behavior predicted lower parental monitoring; for females, greater sexual risk behavior predicted higher perceived peer risk involvement. According to latent growth curve models, a higher initial level of parental monitoring predicted decreases in sexual risk behavior, whereas both a higher initial level and a higher growth rate of peer risk involvement predicted increases in sexual risk behavior. CONCLUSION Results highlight the important influence of peer risk involvement on youths’ sexual behavior and gender differences in reciprocal relationships between parental monitoring, peer influence and adolescent sexual risk behavior.

To determine whether gay men and lesbians disclose their sexual orientation, and other sensitive behaviors to their primary care physicians; whether they have a chance of finding a gay friendly physician; and what factors are involved. A self-report questionnaire was administered to 66 gay men and 28 lesbians at a gay and lesbian community center. Less than half of participants felt their health insurance plan gave them a choice of finding a lesbian, gay, or bisexual (LGB) doctor. Those who did were more likely to be older, male, and to feel more comfortable discussing sex. Men were more likely to disclose their sexual orientation to their health care provider (HCP), to feel very comfortable discussing sex, to have a male doctor, to have a choice of finding a LGB provider through their insurance plan, and to think their provider is LGB. Those who disclosed their sexual orientation to their providers were more likely to be white males with male doctors, who felt their doctor was very gay friendly, and to have also discussed substance use, sexual behavior, and HIV with their HCP, and to feel comfortable discussing sex. Lesbians in particular have difficulty disclosing their sexual orientation to providers, possibly due to continuing stigma, and to have less of a choice of finding a gay or lesbian provider. The data suggest that health insurance plans should provide patients with the opportunity to find gay friendly physicians, as it may facilitate communication about substance use, high risk sexual behavior and other health topics.

A gender discrepancy analysis of heterosexual sexual behaviors in two university samples.

The current study aimed to (1) offer a large-scale enumeration of college students' lifetime sexual behaviors and sexual behaviors at last event, and (2) apply a gender discrepancy lens to college students' sexual behaviors in order to examine potential gender differences in heterosexual college students' experiences. Nine-hundred and seventy college students between the ages of 18 and 27 from two large universities in the United States participated in the current study. Participants filled out a paper-pencil questionnaire during the last 30 min of class. Measures of lifetime sexual behaviors and engagement in behaviors at last sexual event were replicated from the National Survey of Sexual Health Behavior. Most college students engaged in some form of sexual behavior (manual, oral, vaginal-penile, anal). Men more frequently reported engaging in receptive sexual behaviors (e.g., receiving oral sex) where as women were more likely to engage in performative sexual behaviors (e.g., performing oral sex). At most recent sexual event, men were more likely than women to report being the sexual initiator. Findings highlight gender differences in sexual behavior and provide a foundation for social norms interventions. Holistic sexual health promotion for young adults includes acknowledging and discouraging sites of disparity in equity and pleasure. Therefore, college-level sexual health educators should pay attention to the potential pleasure gap between men and women in heterosexual encounters, and to see pleasure as an important part of sexual health that should be included in social norms campaigns.

A new role for GABAergic transmission in the control of male rat sexual behavior expression.

PubMed

Rodríguez-Manzo, Gabriela; Canseco-Alba, Ana

2017-03-01

GABAergic transmission in the ventral tegmental area (VTA) exerts a tonic inhibitory influence on mesolimbic dopaminergic neurons' activity. Blockade of VTA GABA A receptors increases dopamine release in the nucleus accumbens (NAcc). Increases in NAcc dopamine levels typically accompany sexual behavior display. Copulation to satiety is characterized by the instatement of a long lasting (72h) sexual behavior inhibition and the mesolimbic system appears to be involved in this phenomenon. GABAergic transmission in the VTA might play a role in the maintenance of this long lasting sexual inhibitory state. To test this hypothesis, in the present work we investigated the effect of GABA A receptor blockade in sexually exhausted males 24h after copulation to satiety, once the sexual inhibitory state is established, and compared it with its effect in sexually experienced rats. Results showed that low doses of systemically administered bicuculline induced sexual behavior expression in sexually exhausted rats, but lacked an effect on copulation of sexually experienced animals. Intra-VTA bilateral infusion of bicuculline did not modify sexual behavior of sexually experienced rats, but induced sexual behavior expression in all the sexually exhausted males. Hence, GABA plays a role in the control of sexual behavior expression at the VTA. The role played by GABAergic transmission in male sexual behavior expression of animals with distinct sexual behavior conditions is discussed. Copyright © 2016 Elsevier B.V. All rights reserved.

[Pedophilia: contribution of neurology and neuroimaging techniques].

Fonteille, V; Cazala, F; Moulier, V; Stoléru, S

2012-12-01

Pedophilia is characterized by a persistent sexual interest of an adult for prepubescent children. The development of neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI) is starting to clarify the cerebral basis of disorders of sexual behavior such as pedophilia, which had been previously suggested by case studies. To review structural and functional neuroimaging studies of pedophilia. An exhaustive consultation of PubMed and Ovid databases was conducted. We obtained 19 articles presented in the present review of the literature. Case studies have demonstrated various changes of sexual behavior in relation to brain lesions, including the late appearance in adults of a sexual attraction to prepubescent children. In most cases of pedophilia associated with brain lesions, these lesions were located in frontal or in temporal regions. Structural neuroimaging studies have compared pedophiles with healthy subjects and tried to relate pedophilia to anatomical differences between these two groups. The location of structural changes is inconsistent across studies. Recent functional neuroimaging studies have also attempted to investigate the cerebral correlates of pedophilia. Results suggest that the activation pattern found in pedophiles in response to pictures of prepubescent nude girls or boys is similar to the pattern observed in healthy subjects in response to pictures of adult nude women or men. However, regions that become more activated in patients than in healthy controls in response to the presentation of pictures of children vary across studies. Studies that have begun to investigate the cerebral correlates of pedophilia demonstrate that it is possible to explore them through neuroimaging techniques. These initial results have to be confirmed by new studies backed with objective measurements of sexual arousal such as phallometry. Copyright © 2012 L’Encéphale, Paris.

Thailand has undergone dramatic social changes in the last two decades, yet little is known about factors related to sexual initiation among adolescents. A survey using the audio computer-assisted self-interviewing method was conducted to assess social and demographic characteristics, substance use, sexual behavior, and knowledge of HIV and STIs among 1,725 vocational school students aged 15-21 living in northern Thailand. Gender differences for these factors were evaluated using chi-square and Mann-Whitney U tests. Multivariate survival analysis using Cox proportional hazards models assessed associations between these variables and sexual initiation for each gender. Males initiated sexual intercourse at an earlier age than females (median ages of 17 and 18, respectively). At any given age, sexual initiation was associated with having a nonagricultural background and using alcohol or methamphetamine (adjusted rate ratios, 1.3-2.9). For males, initiation was also associated with having parents who did not live together, having a friend as a confidant, tobacco use, high perceived risk for HIV and high STI knowledge (1.3-1.7). For females, other factors associated with earlier initiation were younger age at interview, living away from family, lacking a family member as a confidant, high perceived risk for STIs and ever having smoked marijuana (1.3-2.4). Interventions to ameliorate the adverse consequences of early sexual initiation need to address social influences such as parents and peer groups. Programs should identify and target high-risk subgroups, such as those who are sexually experienced at an early age and those engaged in patterns of generalized risk-taking.

The number of HIV cases attributed to heterosexual contact and the proportion of women among HIV positive individuals has increased worldwide. Russia is a country with the highest rates of newly diagnosed HIV infections in the region, and the infection spreads beyond traditional risk groups. While young women are affected disproportionately, knowledge of HIV risk behaviors in women in the general population remains limited. The objectives of this study were to identify patterns of behaviors that place women of childbearing age at high risk for HIV transmission and determine whether socio-demographic characteristics and alcohol use are predictive of the risk pattern. A total of 708 non-pregnant women, aged between 18 and 44 years, who were at risk for an alcohol-exposed pregnancy were enrolled in two regions in Russia. Participants completed a structured interview focused on HIV risk behaviors, including risky sexual behavior and alcohol and drug use. Latent class analysis was utilized to examine associations between HIV risk and other demographic and alcohol use characteristics and to identify patterns of risk among women. Three classes were identified. 34.93% of participants were at high risk, combining their risk behaviors, e.g., having multiple sexual partners, with high partner's risk associated with partner's drug use (class I). Despite reporting self-perceived risk for HIV/STI, this class of participants was unlikely to utilize adequate protection (i.e., condom use). The second high risk class included 13.19% of participants who combined their risky sexual behaviors, i.e., multiple sexual partners and having STDs, with partner's risk that included partner's imprisonment and partner's sex with other women (class II). Participants in this class were likely to utilize protection/condoms. Finally, 51.88% of participants were at lower risk, which was associated primarily with their partners' risk, and these participants utilized protection (class III). The odds of being in class I compared with class III were 3.3 (95% CI [1.06, 10.38]) times higher for those women who had Alcohol Use Disorders Identification Test scores ≥ 8 than those who had lower scores, and were 3.9 (95% CI [1.69, 8.97]) times higher for those who used alcohol before sex than those who did not. In addition, women who drank more days per week were 1.36 times more likely to be in class II than in class III. The study informs prevention by identifying specific population groups and targets for interventions. Alcohol use is a significant predictor and an overarching factor of HIV risk in women. Since at-risk drinking is common among young Russian women, alcohol risk reduction should be an essential component of HIV prevention efforts.

Research examining the sexual behaviors and experiences of behaviorally bisexual men is limited. Most studies focus primarily on highlighting sexual risk behaviors among groups of “men who have sex with men (MSM)” or “gay and bisexual men,” which may not be appropriate in terms of behaviorally bisexual men’s sexual repertoires with both men and women. This study aimed to assess a broad range of sexual behaviors and associated experiences among bisexual men living in the midwestern United States. An interviewer-administered questionnaire containing items from the National Survey of Sexual Health and Behavior assessed lifetime and recent (i.e., past six months and last event) sexual behaviors and experiences with both male and female partners among a diverse sample of 75 behaviorally bisexual men. Responses were quantified and analyzed using descriptive and multivariate statistics. A wide range of sexual behaviors with partners of both genders was found. Vaginal intercourse and oral sex with both men and women were the most commonly reported behaviors. Subjective reports of pleasure, arousal, and sexual function during sexual activity were similar with both male and female partners. Many participants reported using condoms during insertive sexual behaviors with male and female partners, but less during oral sex. Unprotected receptive anal sex was less commonly reported. Overall, participants reported a variety of sexual behaviors and experiences; however, unlike other populations, they shared these with partners of both genders. Results have implications for interventions targeting the sexual behaviors and associated issues among behaviorally bisexual men. PMID:22187027

Background The prostate is a sexual gland that produces important substances for the potency of sperm to fertilize eggs within the female reproductive tract, and is under complex endocrine control. Taking advantage of the peculiar behavioral pattern of copulating male rats, we developed experimental paradigms to determine the influence of sexual behavior on the level of serum testosterone, prostate androgen receptors, and mRNA for androgen receptors in male rats displaying up to four consecutive ejaculations. Methods The effect of four consecutive ejaculations was investigated by determining levels of (i) testosterone in serum by solid phase RIA, (ii) androgen receptors at the ventral prostate with Western Blots, and (iii) androgen receptors-mRNA with RT-PCR. Data were analyzed with a one-way ANOVA followed by a post hoc application of Dunnett's test if required. Results The constant execution of sexual behavior did not produce any change in the weight of the ventral prostate. Serum testosterone increased after the second ejaculation, and remained elevated even after four ejaculations. The androgen receptor at the ventral prostate was higher after the first to third ejaculations, but returned suddenly to baseline levels after the fourth ejaculation. The level of mRNA increased after the first ejaculation, continued to increase after the second, and reached the highest peak after the third ejaculation; however, it returned suddenly to baseline levels after the fourth ejaculation. Conclusion Four consecutive ejaculations by sexually experienced male rats had important effects on the physiological responses of the ventral prostate. Fast responses were induced as a result of sexual behavior that involved an increase and decrease in androgen receptors after one and four ejaculations, respectively. However, a progressive response was observed in the elevation of mRNA for androgen receptors, which also showed a fast decrease after four ejaculations. All of these changes with the prostate gland occurred in the presence of a sustained elevation of testosterone in the serum that started after two ejaculations. A consideration of these fast-induced changes suggests that the nerve supply plays a key role in prostate physiology during the sexual behavior of male rats. PMID:17367532

Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity. PMID:24215966

Parents, Peers, and Sexual Values Influence Sexual Behavior During the Transition to College

Several decades of research have identified the contributions of psychosocial influences on adolescent and young adult sexual behavior; however, few studies have examined parental and peer influence and sexual values during the transition from high school to college. The current study tested the influence of sexual values and perceived awareness and caring (PAC), or beliefs about how much parents and peers know and care about students’ behavior, on sexual behavior during this transitional period. Using data from a longitudinal study, generalized estimating equations and the generalized linear model were used to examine the associations among sexual values, parental and peer PAC, and sexual behavior, both cross-sectionally and longitudinally. Participants (N = 1,847; 61% female) completed web-based surveys the summer before college matriculation and at the end of the first semester in college. Results indicated that individuals with high levels of both parental and peer PAC engaged in less frequent sexual behaviors and that PAC moderated the effect of sexual values on sexual behaviors. Furthermore, both PAC variables decreased during the transition from high school to college, and high school sexual values, parental PAC, and their interaction predicted the number of sexual partners during the first semester of college. Only sexual values and high school unsafe sexual behaviors predicted unsafe sexual behavior in college. Findings suggest that complex associations exist among perceived awareness and caring, sexual values, and sexual behaviors, and that the transition from high school to college may be an ideal time for safer-sex interventions.

Child sexual abuse has the potential to cause distress for the victim across the lifespan. Romantic relationships may be particularly difficult for victims of child sexual abuse. This retrospective study examined differences in adult romantic attachment, sexually compulsive behaviors, and emotion regulation by history of child sexual abuse in a large, nonclinical sample. Those with a history of child sexual abuse reported more attachment anxiety in romantic relationships and engaged in more sexually compulsive behaviors. Overall, males displayed more sexually compulsive behaviors than females regardless of history of sexual abuse. Males with a history of sexual abuse displayed the greatest number of sexually compulsive behaviors. Surprisingly, no differences were observed in emotion regulation or attachment avoidant behaviors by history of child sexual abuse. Future research should seek to replicate current findings and examine emotion regulation difficulties experienced as a result of trauma.

Turchik, Jessica A; Hassija, Christina M

2014-09-01

The purpose of the present study was to examine the relationship between college women's sexual victimization experiences, health risk behaviors, and sexual functioning. A sample of 309 college women at a mid-sized Midwestern university completed measures assessing sexual victimization, sexual risk taking, substance use behaviors, sexual desire, sexual functioning, prior sexual experiences, and social desirability. Severity of sexual victimization was measured using a multi-item, behaviorally specific, gender-neutral measure, which was divided into four categories based on severity (none, sexual contact, sexual coercion, rape). Within the sample, 72.8% (n = 225) of women reported at least one experience of sexual victimization since age 16. Results from MANCOVAs and a multinomial logistic regression, controlling for social desirability and prior sexual experience, revealed that sexual victimization among female students was related to increased drug use, problematic drinking behaviors, sexual risk taking, sexual dysfunction, and dyadic sexual desire. In addition, findings indicated that women exposed to more severe forms of sexual victimization (i.e., rape) were most likely to report these risk-taking behaviors and sexual functioning issues. Implications for sexual assault risk reduction programming and treatment are discussed. © The Author(s) 2014.

This is a report of a cross-sectional study on paraphilia-associated sexual arousal patterns (PASAP) among men in a metropolitan city in Germany, EU. To determine the prevalence of PASAP during sexual fantasies, fantasies accompanying masturbation, and real-life sociosexual behavior. In a cross-sectional study, self-reported sexual history data were collected by questionnaire from 367 volunteers recruited from a community sample of 1,915 men aged 40-79 years. The Derogatis Symptom Checklist-Revised (SCL-90-R) and the Life Satisfaction Questionnaire (LSQ; German original, Fragebogen zur Lebenszufriedenheit, [FLZ]) were administered to obtain a general subjective health measure and a measure of general as well as sex life satisfaction. The Questionnaire on Sexual Experiences and Behaviour was administered to comprehensively assess all relevant sexo-medical data. Results.  The percent of men that reported at least one PASAP was 62.4%. In 1.7% of cases, PASAP were reported to have caused distress. The presence of PASAP was associated with a higher likelihood of being single (odds ratio [OR] 2.6; 95%; confidence interval [CI] 1.047-6.640), masturbating at least once per week (OR 4.4; 95%; CI 1.773-10.914), or having a low general subjective health score (OR 11.9; 95%; CI 2.601-54.553). Pedophilic PASAP in sexual fantasies and in real-life sociosexual behavior was reported by 9.5% and 3.8% of participants, respectively. The findings suggest that paraphilia-related experience can not be regarded as unusual from a normative perspective. At the same time, many men experience PASAP without accompanying problem awareness or distress, even when PASAP contents are associated with potentially causing harm to others. In view of the relevance for sex life and relationship satisfaction, presence of PASAP should be assessed in all sexual medicine consultations. Future research should focus on conditions in which PASAP reach clinical significance in the sense of mental disorders. © 2009 International Society for Sexual Medicine.

Many studies have examined differences in sexual behavior based on sexual orientation with results often indicating that those with same-sex partners engage in higher risk sexual behavior than people with opposite sex partners. However, few of these studies were large, national sample studies that also include those identifying as unsure. To address that gap, this study examined the relationship of sexual orientation and sexual health outcomes in a national sample of U.S. college students. The Fall 2009 American College Health Association-National College Health Assessment was used to examine sexual health related responses from heterosexual, gay, lesbian, bisexual, and unsure students (N = 25,553). Responses related to sexual behavior, safer sex behaviors, prevention and screening behaviors, and diagnosis of sexual health related conditions were examined. The findings indicated that sexual orientation was significantly associated with engaging in sexual behavior in the last 30 days. Sexual orientation was also significantly associated with the number of sexual partners in the previous 12 months, with unsure men having significantly more partners than gay, bisexual and heterosexual men and heterosexual men having significantly less partners than gay, bisexual and unsure men. Bisexual women had significantly more partners than females reporting other sexual orientations. Results examining the associations between sexual orientation and safer sex, prevention behaviors, and screening behaviors were mixed. Implications for practice, including specific programmatic ideas, were discussed.

It is known that olfaction is essential for the occurrence of sexual behavior in male goldfish. Sex pheromones from ovulatory females elicit male sexual behavior, chasing, and sperm releasing act. In female goldfish, ovarian prostaglandin F2α (PGF) elicits female sexual behavior, egg releasing act. It has been considered that olfaction does not affect sexual behavior in female goldfish. In the present study, we re-examined the involvement of olfaction in sexual behavior of female goldfish. Olfaction was blocked in male and female goldfish by two methods: nasal occlusion (NO) which blocks the reception of olfactants, and olfactory tract section (OTX) which blocks transmission of olfactory information from the olfactory bulb to the telencephalon. Sexual behavior of goldfish was induced by administration of PGF to females, an established method for inducing goldfish sexual behavior in both sexes. Sexual behavior in males was suppressed by NO and OTX as previously reported because of lack of pheromone stimulation. In females, NO suppressed sexual behavior but OTX did not affect the occurrence of sexual behavior. Females treated with both NO and OTX performed sexual behavior normally. These results indicate that olfaction is essential in female goldfish to perform sexual behavior as in males but in a different manner. The lack of olfaction in males causes lack of pheromonal stimulation, resulting in no behavior elicited. Whereas the results of female experiments suggest that lack of olfaction in females causes strong inhibition of sexual behavior mediated by the olfactory pathway. Olfactory tract section is considered to block the pathway and remove this inhibition, resulting in the resumption of the behavior. By subtract sectioning of the olfactory tract, it was found that this inhibition was mediated by the medial olfactory tracts, not the lateral olfactory tracts. Thus, it is concluded that goldfish has gender-typical olfactory regulation for sexual behavior. PMID:24817840

Although poppers are increasingly popular among MSM in China, little is known about the patterns of poppers use. The objectives of this study were to describe the patterns of poppers use and examine its association with sexual behaviors and HIV infection among MSM in Beijing, China. As part of a multi-component HIV intervention trial, 3588 MSM were surveyed between March 2013 and March 2014 in Beijing, China. Blood samples were collected and tested for HIV and syphilis. The questionnaire collected information about socio-demographic and behavioral characteristics. Univariate and multivariable logistic regression analyses were performed to evaluate the correlates of poppers use. Over a quarter of men (27.5%) reported having used at least one type of drugs in the past three months. Poppers were the most popular one (26.8%). Poppers use was correlated with a higher HIV prevalence [odds ratio (OR): 1.38, 95% confidence interval (CI): 1.11-1.70]. Demographic and sexual behavioral factors associated with poppers use included: younger age [adjusted OR (AOR): 1.56, 95% CI: 1.25-1.94], higher education (AOR: 1.61, 95% CI: 1.33-1.96), alcohol use (AOR: 1.32, 95% CI: 1.10-1.60), seeking male partners mainly via the internet (AOR: 1.60, 95% CI: 1.28-2.00), multiple male sex partnership (AOR: 2.22, 95% CI: 1.90-2.60), and unprotected receptive anal intercourse (AOR: 1.52, 95% CI: 1.28-1.81). In this study, poppers use was positively associated with HIV infection and unprotected anal intercourse. Intervention efforts should be devoted to promote safer sex and HIV testing and counseling among MSM who use poppers. Copyright © 2016. Published by Elsevier Ireland Ltd.

The authors used the theory of planned behavior to examine the influence of parents and peers on early adolescent sexual attitudes, self-efficacy to limit sexual behavior, and behavioral intentions to have vaginal intercourse. Adolescents (N = 212) provided self-reports of their perception of parent and peer attitudes regarding sexual behavior. The authors used bivariate and regression analyses to examine the relation between parent and peer attitudes with adolescent sexual attitudes, self-efficacy to limit sexual behavior, and behavioral intentions to have vaginal intercourse. Although there were gender differences, the analyses revealed the importance of both parents and peers on adolescent sexual attitudes, self-efficacy to limit sexual behavior, and intentions to have vaginal sex in the next year.

This study explored perceptions about sexual behaviors and attitudes of adolescents living in Soweto, Johannesburg, South Africa, from the perspective of parents, counselors and adolescents. A qualitative methodology was applied. Nine focus group discussions (FGDs) were held; three with parents of adolescents, two with counselors who work with adolescents, two with female adolescents aged 16-18 years and two with male adolescents aged 16-18 years. In total, 80 participants were recruited from in and around Soweto. FGDs were guided by a semi-structured interview guide, audio-recorded, transcribed verbatim and translated into English. Data were analyzed using Maxqda, a qualitative software analysis program. There were eight key themes related to adolescent sexuality and perceived attitudes towards relationships. Five themes were common to all participant groupings (parents, counselors and adolescents): (1) dating during adolescence, (2) adolescent females dating older males, (3) condom use amongst adolescents, (4) pregnancy and (5) homosexuality. (6) Sex as a regular and important activity among adolescents and (7) group sex practices among adolescents emerged as themes from adolescent and counselor FGDs. Lastly, (8) the role of the media as an influence on adolescent sexuality was common to adolescent and parent groups. Risky sexual behaviors continue among adolescents, with group sex parties a concerning emergent phenomenon that necessitates further study. HIV, other STIs and pregnancy prevention interventions should address multiple levels of influence to address context-specific influences. PMID:22844344

Adolescent sexual risk behavior can lead to serious health consequences, yet few investigations have addressed its neurodevelopmental mechanisms. Social neurocircuitry is postulated to underlie the development of risky sexual behavior, and response to social reward may be especially relevant. Typically developing adolescents (N=47; 18M, 29F; 16.3±1.4 years; 42.5% sexual intercourse experience) completed a social reward fMRI task and reported their sexual risk behaviors (e.g., lifetime sexual partners) on the Youth Risk Behavior Survey (YRBS). Neural response and functional connectivity to social reward were compared for adolescents with higher- and lower-risk sexual behavior. Adolescents with higher-risk sexual behaviors demonstrated increased activation in the right precuneus and the right temporoparietal junction during receipt of social reward. Adolescents with higher-risk sexual behaviors also demonstrated greater functional connectivity between the precuneus and the temporoparietal junction bilaterally, dorsal medial prefrontal cortex, and left anterior insula/ventrolateral prefrontal cortex. The greater activation and functional connectivity in self-referential, social reward, and affective processing regions among higher sexual risk adolescents underscores the importance of social influence underlying sexual risk behaviors. Furthermore, results suggest an orientation towards and sensitivity to social rewards among youth engaging in higher-risk sexual behavior, perhaps as a consequence of or vulnerability to such behavior.

The present study examined negative life events (NLEs) and sexual assault victimization as predictors of positive and negative psychological functioning in a sample of 151 female college students. Results obtained from conducting regression analyses indicated several notable patterns. NLEs, compared with sexual assault victimization, were a stronger negative predictor of positive functioning based on indices related to subjective well-being (e.g., life satisfaction, positive affect). Alternatively, sexual assault victimization, compared with NLEs, was a stronger positive predictor of negative functioning based on indices related to posttraumatic stress disorder symptoms (e.g., anxiety) and related conditions (e.g., alcohol use). Furthermore, both NLEs and sexual assault victimization were found to be positive predictors of negative functioning based on indices related to suicide risk (e.g., depressive symptoms, suicidal behaviors). Overall, our findings indicate that both NLEs and sexual assault victimization represent important and distinct predictors of psychological functioning in female college students.

Previous studies have indicated that viewing sexually explicit media (SEM) might be associated with sexual risk behaviors in men who have sex with men (MSM). However, most prior research has not explored this association cross-culturally or the potential influence that important covariates might have on the association. To explore the association between self-reports of viewing SEM depicting various sexual risk behaviors and engagement in sexual risk behaviors after controlling for relevant covariates in MSM in China. Three hundred fourteen Chinese MSM participated in a web-based survey. SEM consumption, sexual risk behavior, and measurements of covariates. SEM consumption was frequent in MSM in China. Viewing a larger proportion of SEM depicting sexual risk behaviors was associated with a larger number of regular partners with whom MSM reported engaging in sexual risk behaviors, but not with the number of casual partners, after controlling for covariates. HIV-related knowledge and seeking male sex partners were associated with the number of regular partners with whom MSM had engaged in sexual risk behaviors. Seeking sexual sensation, HIV-related knowledge, and seeking male sex partners were associated with the number of casual partners with whom MSM had engaged in sexual risk behaviors. Future research exploring the relation between SEM use and sexual health risk behaviors should consider theoretically important psychological and behavioral covariates. Xu Y, Zheng Y, Rahman Q.

Dopamine (DA) plays a central role in the expression of male sexual behavior. The effects of DA-enhancing drugs on copulation seem to vary depending on the dose of the agonist used, the type of DA receptor activated, and the sexual condition of the animals. The aim of the present study was to carry out a systematic analysis of the effects of dopaminergic agonists on the expression of male sexual behavior by sexually competent rats in different sexual motivational states, that is when sexually active (sexually experienced) and when temporarily inhibited (sexually exhausted). To this end, the same doses of the nonselective DA receptor agonist apomorphine, the selective D2-like DA receptor agonist quinpirole, and the selective D1-like DA receptor agonist SKF38393 were injected intraperitoneally to sexually experienced or sexually exhausted male rats and their sexual behavior was recorded. Low apomorphine doses induced expression of sexual behavior in sexually satiated rats, but only reduced the intromission latency of sexually experienced rats. SKF38393 facilitated the expression of sexual behavior by sexually exhausted rats, but not that of sexually experienced males and quinpirole did not exert an effect in both types of animal. In line with these results, the apomorphine-induced reversal of sexual exhaustion was blocked by the D1-like receptor antagonist SCH23390. The data suggest that DA receptors play distinct roles in the expression of sexual behavior by male rats depending on their motivational state and that activation of D1-like receptors promotes the expression of sexual behavior in satiated rats.

Pedophilia is a sexual preference that is often associated with child sex offending (CSO). Sexual urges towards prepubescent children and specifically acting upon those urges are universally regarded as immoral. However, up until now, it is completely unknown whether moral processing of sexual offenses is altered in pedophiles. A total of 31 pedophilic men and 19 healthy controls were assessed by using functional magnetic resonance imaging (fMRI) in combination with a moral judgment paradigm consisting of 36 scenarios describing different types of offenses.Scenarios depicting sexual offenses against children compared to those depicting adults were associated with higher pattern of activation in the left temporo-parietal-junction (TPJ) and left posterior insular cortex, the posterior cingulate gyrus as well as the precuneus in controls relative to pedophiles, and vice versa. Moreover, brain activation in these areas were positively associated with ratings of moral reprehensibility and negatively associated with decision durations, but only in controls. Brain activation, found in key areas related to the broad network of moral judgment, theory of mind and (socio-)moral disgust - point to different moral processing of sexual offenses in pedophilia in general. The lack of associations between brain activation and behavioral responses in pedophiles further suggest a biased response pattern or dissected implicit valuation processes. © The Author (2017).

Is There a Weekly Pattern for Health Searches on Wikipedia and Is the Pattern Unique to Health Topics?

2015-12-22

Online health information-seeking behaviors have been reported to be more common at the beginning of the workweek. This behavior pattern has been interpreted as a kind of "healthy new start" or "fresh start" due to regrets or attempts to compensate for unhealthy behavior or poor choices made during the weekend. However, the observations regarding the most common health information-seeking day were based only on the analyses of users' behaviors with websites on health or on online health-related searches. We wanted to confirm if this pattern could be found in searches of Wikipedia on health-related topics and also if this search pattern was unique to health-related topics or if it could represent a more general pattern of online information searching--which could be of relevance even beyond the health sector. The aim was to examine the degree to which the search pattern described previously was specific to health-related information seeking or whether similar patterns could be found in other types of information-seeking behavior. We extracted the number of searches performed on Wikipedia in the Norwegian language for 911 days for the most common sexually transmitted diseases (chlamydia, gonorrhea, herpes, human immunodeficiency virus [HIV], and acquired immune deficiency syndrome [AIDS]), other health-related topics (influenza, diabetes, and menopause), and 2 nonhealth-related topics (footballer Lionel Messi and pop singer Justin Bieber). The search dates were classified according to the day of the week and ANOVA tests were used to compare the average number of hits per day of the week. The ANOVA tests showed that the sexually transmitted disease queries had their highest peaks on Tuesdays (P<.001) and the fewest searches on Saturdays. The other health topics also showed a weekly pattern, with the highest peaks early in the week and lower numbers on Saturdays (P<.001). Footballer Lionel Messi had the highest mean number of hits on Tuesdays and Wednesdays, whereas pop singer Justin Bieber had the most hits on Tuesdays. Both these tracked search queries also showed significantly lower numbers on Saturdays (P<.001). Our study supports prior studies finding an increase in health information searching at the beginning of the workweek. However, we also found a similar pattern for 2 randomly chosen nonhealth-related terms, which may suggest that the search pattern is not unique to health-related searches. The results are potentially relevant beyond the field of health and our preliminary findings need to be further explored in future studies involving a broader range of nonhealth-related searches.

Ethnic, Gender, and Acculturation Influences on Sexual Behaviors

Ahrold, Tierney

2015-01-01

Much research has been conducted on ethnic differences in sexuality, but few studies have systematically assessed the importance of acculturation in sexual behavior. The present study assessed general differences in normative sexual practices in healthy Euro-American, Asian, and Hispanic populations, using measures of acculturation to analyze the relative effects of heritage and mainstream cultures within each group. A total of 1,419 undergraduates (67% Euro-American, 17% Hispanic, 16% Asian; 33% men, 67% women) completed questionnaires which assessed sexual experience and causal sexual behaviors. In concordance with previous studies, Asians reported more conservative levels of sexual experience and frequency of sexual behaviors, fewer lifetime partners, and later ages of sexual debut than Euro-American or Hispanic counterparts. Hispanic reported sexual experiences similar to that of Euro-Americans. There was a significant interaction between mainstream and heritage acculturation in predicting number of lifetime sexual partners in Asian women such that the relationship between heritage acculturation and casual sexual behavior was stronger at lower levels of mainstream acculturation. On the other hand, in Hispanic men, higher levels of mainstream acculturation predicted more casual sexual behavior (one-time sexual encounters and number of lifetime sexual partners) when heritage acculturation was low but less casual sexual behavior when heritage acculturation was high. These results suggest that, for sexual behavior, Hispanic men follow an “ethnogenesis” model of acculturation while Asian women follow an “assimilation” model of acculturation. PMID:18931901

The association of sexual interest and sexual behaviors among adolescent women: A daily diary perspective

2011-01-01

Theoretical and empirical linkages of adult women’s sexual interest and sexual behaviors are relatively well-established, but few data address similar issues in adolescent women. This paper reviews data from published reports of associations of adolescent women’s sexual interest and various sexual behaviors. All of the papers reported data collected from a single longitudinal cohort of young women. The primary source of data collection was daily diaries, allowing close temporal pairing of sexual interest with sexual behaviors. Young women’s sexual interest on a given day was consistently and independently associated with sexual activity on that day, whether the behavior was first lifetime coitus, coitus, fellatio, cunnilingus, anal intercourse, or coitus during menses. We also found no evidence of influence of hormonal contraceptives on young women’s sexual interest. Taken together, these data demonstrate the relevance of sexual interest as a key factor in young women’s sexuality and sexual behavior. PMID:21397605

Investigations of patterns of sexual arousal to certain groups of sexually explicit media (SEM) in the general population in non-laboratory settings are rare. Such knowledge could be important to understand more about the relative specificity of sexual arousal in different SEM users. (i) To investigate whether sexual arousal to non-mainstream vs mainstream SEM contents could be categorized across gender and sexual orientation, (ii) to compare levels of SEM-induced sexual arousal, sexual satisfaction, and self-evaluated sexual interests and fantasies between non-mainstream and mainstream SEM groups, and (iii) to explore the validity and predictive accuracy of the Non-Mainstream Pornography Arousal Scale (NPAS). Online cross-sectional survey of 2,035 regular SEM users in Croatia. Patterns of sexual arousal to 27 different SEM themes, sexual satisfaction, and self-evaluations of sexual interests and sexual fantasies. Groups characterized by sexual arousal to non-mainstream SEM could be identified across gender and sexual orientation. These non-mainstream SEM groups reported more SEM use and higher average levels of sexual arousal across the 27 SEM themes assessed compared with mainstream SEM groups. Only few differences were found between non-mainstream and mainstream SEM groups in self-evaluative judgements of sexual interests, sexual fantasies, and sexual satisfaction. The internal validity and predictive accuracy of the NPAS was good across most user groups investigated. The findings suggest that in classified non-mainstream SEM groups, patterns of sexual arousal might be less fixated and category specific than previously assumed. Further, these groups are not more judgmental of their SEM-related sexual arousal patterns than groups characterized by patterns of sexual arousal to more mainstream SEM content. Moreover, accurate identification of non-mainstream SEM group membership is generally possible across gender and sexual orientation using the NPAS. Hald GM, Stulhofer A, Lange T, et al.

2017-01-01

Previous research has shown an association between child maltreatment (sexual abuse, physical abuse, neglect or witnessing interparental violence) and adolescent sexual risk behaviors. The mechanisms explaining this association are not well understood but attachment theory could provide further insight into them. This study examined the relationships between child maltreatment and sexual risk behaviors and investigated anxious and avoidant attachment as mediators. The sample comprised 1,900 sexually active adolescents (13 to 17 years old; 60.8% girls) attending Quebec high schools. The results of path analyses indicated that neglect was associated with a higher number of sexual partners, casual sexual behavior, and being younger at first intercourse. Anxious attachment mediated the relation between neglect and number of sexual partners, whereas avoidant attachment explained the relation between neglect and number of sexual partners, casual sexual behavior, and age at first intercourse (for boys only). Sexual abuse was directly associated with all three sexual risk behaviors. Neither anxious attachment nor avoidant attachment mediated these associations. Youth with a history of neglect and sexual abuse represent a vulnerable population that is likely to engage in sexual risk behaviors. Interventions designed to induce a positive change in attachment security may reduce sexual risk behaviors among victims of neglect. PMID:28467103

Objective This study examined the relationship between violence exposure and sexual risk-taking among low-income, urban African American (AA) adolescent girls, considering overlap among different types and characteristics of violence. Methods AA adolescent girls were originally recruited from outpatient mental health clinics serving urban, mostly low-SES communities in Chicago, IL as part of a two-year longitudinal investigation of HIV-risk behavior. A subsequent follow-up was completed to assess lifetime history of trauma and violence exposure. The current study (N=177) included violence exposure and sexual risk behavior reported at the most recent interview (ages 14-22). Multiple regression was used to examine combined and unique contributions of different types, ages, settings, and perpetrators or victims of violence to variance in sexual risk. Results More extensive violence exposure and cumulative exposure to different kinds of violence were associated with overall unsafe sex, more partners, and inconsistent condom use. The most significant unique predictors, accounting for overlap among different forms of violence, were physical victimization, adolescent exposure, neighborhood violence, and violence involving dating partners. Conclusions These findings put sexual risk in the context of broad traumatic experiences but also suggest that the type and characteristics of violence exposure matter in terms of sexual health outcomes. Violence exposure should be addressed in efforts to reduce STIs among low-income, urban African American girls. PMID:24563808

Poor Parenting, Attachment Style, and Dating Violence Perpetration Among College Students.

PubMed

Tussey, Brian Ermon; Tyler, Kimberly A; Simons, Leslie Gordon

2018-02-01

Although dating violence is prevalent among college students, little is known about how both attachment style and participation in risky behaviors contribute to this pattern of violence. To address this literature gap, we examine the role of poor parenting, child abuse, attachment style, and risky sexual and drug use behaviors on dating violence perpetration among 1,432 college students (51% female). Path analysis results revealed that females were more likely to report greater attachment anxiety but lower attachment avoidance compared with males. Correlates of attachment anxiety included child physical abuse, witnessing parental violence, and poorer maternal relationship quality whereas attachment avoidant behavior was linked to more physical abuse and poorer maternal relationship quality. Females were more likely to perpetrate dating violence as were those with greater attachment anxiety and lower attachment avoidance. Other correlates of dating violence perpetration included sexual and drug risk behaviors. Finally, distal factors (i.e., more child physical abuse and poorer maternal relationship quality) also were associated with dating violence perpetration. Study implications are also discussed.

The Role of Sexual Health Professionals in Developing a Shared Concept of Risky Sexual Behavior as it Relates to HIV Transmission.

"Risky sexual behavior" accounts for the majority of new HIV infections regardless of gender, age, geographic location, or ethnicity. The phrase, however, refers to a relatively nebulous concept that hampers development of effective sexual health communication strategies. The purpose of this paper was to propose development of a shared conceptual understanding of "risky sexual behavior." We reviewed multidisciplinary HIV/AIDS literature to identify definitions of risky sexual behavior. Both the linguistic components and the social mechanisms that contribute to the concept of risky sexual behaviors were noted. Risky sexual behavior was often defined in a subjective manner in the literature, even in the scientific research. We urge a paradigm shift to focus on explicit behaviors and the social context of those behaviors in determining HIV risk. We also propose a new definition that reduces individual biases and promotes a broader discussion of the degree of sexual risk across a diversity of behavioral contexts. Sexual health professionals can strengthen practice and research initiatives by operating from a concise working definition of risky sexual behavior that is broadly transferable and expands beyond a traditional focus on identity-based groups. © 2015 Wiley Periodicals, Inc.

Purpose This study examined the association between early initiation of problem behaviors (alcohol drinking, cigarette smoking, and sexual intercourse) and suicidal behaviors (suicidal ideation and suicide attempts), and explored the effect of concurrent participation in these problem behaviors on suicidal behaviors among Korean adolescent males and females. Materials and Methods Data were obtained from the 2006 Korean Youth Risk Behavior Survey, a nationally representative sample of middle and high school students (32,417 males and 31,467 females) in grades seven through twelve. Bivariate and multivariate logistic analyses were conducted. Several important covariates, such as age, family living structure, household economic status, academic performance, current alcohol drinking, current cigarette smoking, current butane gas or glue sniffing, perceived body weight, unhealthy weight control behaviors, subjective sleep evaluation, and depressed mood were included in the analyses. Results Both male and female preteen initiators of each problem behavior were at greater risk for suicidal behaviors than non-initiators, even after controlling for covariates. More numerous concurrent problematic behaviors were correlated with greater likelihood of seriously considering or attempting suicide among both males and females. This pattern was more clearly observed in preteen than in teen initiators although the former and latter were engaged in the same frequency of problem behavior. Conclusion Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors. PMID:20046509

A large sample of 2-12 year old children (N = 2311) was studied to determine the relationship between three sexually intrusive behavior items (SIBs) measured by the Child Sexual Behavior Inventory (CSBI) and a range of developmental, ecological, and behavioral correlates. The variables studied included age, gender, race, family income, single parent status, maternal education, family sexual behaviors, physical abuse, sexual abuse, domestic violence, social competence of the child, and three scales from the CBCL (Internalizing, Externalizing, and PTSD). Sexual abuse was not the primary predictor of SIB, but a model incorporating family adversity, modeling of coercive behavior, child behavior, and modeling of sexuality predicted a significant amount of variance.

Evidence suggests there are important sexual-orientation differences in alcohol consumption, particularly among women. Little is known about where gay/lesbian and bisexual college students drink or differences in drinking patterns derived from graduated frequency measures between heterosexual, gay/lesbian, and bisexual students. The goal of this analysis was to examine patterns of alcohol consumption-including drinking prevalence, quantity, frequency, and contexts of use-by sexual orientation. Data on sexual identity, gender, drinking behaviors, and drinking contexts were examined from repeated cross-sectional samples of undergraduate students attending 14 public California universities from 2003-2011 (n=58,903). Multivariable statistical techniques were employed to examine sexual-orientation differences stratified by gender. Gay males, lesbians, and bisexual females were significantly more likely to report drinking alcohol in the current semester than their same-gender heterosexual peers (relative risks ranged from 1.07 to 1.10, p-values <0.01). Among current drinkers, bisexual females consumed 7 or more drinks and lesbians consumed 10 or more drinks on significantly more days than heterosexual females. On the other hand, gay male drinkers consumed 8 or more drinks on significantly fewer days than heterosexual male drinkers. Compared to their same-gender heterosexual peers: lesbian/gay and bisexual students drank less frequently at Greek parties (incidence rate ratios [IRRs] ranged from 0.52 to 0.73, p-values <0.01); lesbians (IRR=0.84, p=0.043) and bisexual males (IRR=0.82, p=0.009) drank less frequently at off-campus parties; and gay males drank more frequently outdoors (IRR=1.63, p<0.001) and at bars/restaurants (IRR=1.21, p=0.013). Alcohol prevention programs and future research should consider sexual-orientation differences in drinking patterns and use of drinking contexts. Copyright © 2016 Elsevier Ireland Ltd.

Not much is known about whether women who follow Pap testing recommendations report the same pattern of sexual behavior as women who do not. Data come from part of a larger population-based computer-assisted telephone survey of 8656 Australians aged 16-64 years resident in Australian households with a fixed telephone line (Australian Longitudinal Study of Health and Relationships [ALSHR]). The main outcome measure in the current study was having had a Pap test in the past 2 years. Data on a weighted sample of 4052 women who reported sexual experience (ever had vaginal intercourse) were analyzed. Overall, 73% of women in the sample reported having a Pap test in the past 2 years. Variables individually associated with Pap testing behavior included age, education, occupation, cohabitation status, residential location, tobacco and alcohol use, body mass index (BMI), lifetime and recent number of opposite sex partners, sexually transmitted infection (STI) history, and condom reliance for contraception. In adjusted analyses, women in their 30s, those who lived with their partner, and nonsmokers were more likely to have had a recent Pap test. Those who drank alcohol at least weekly were more likely to have had a recent test than irregular drinkers or nondrinkers. Women with no sexual partners in the last year were less likely to have had a Pap test, and women who reported a previous STI diagnosis were more likely to have had a Pap test in the past 2 years. There are differences in Pap testing behavior among Australian women related to factors that may affect their risk of developing cervical abnormalities. Younger women and regular smokers were less likely to report a recent test. Screening programs should consider the need to focus recruitment strategies for these women.

This article reports on a combined family-based substance abuse and HIV prevention intervention targeting families with children ages 13-14 in Bangkok, Thailand. Families (n=340) were randomly and proportionally selected from seven districts in Bangkok with half randomly assigned to an experimental or control condition. Families in the intervention condition were exposed to five interactive booklets about adolescent substance use and risky sexual behavior. Trained health educators followed up by phone to encourage completion of each booklet. Primary outcomes reported in this paper include whether the intervention increased the frequency of parent/child communication in general or about sexual risk taking in particular as well as whether the intervention reduced discomfort discussing sexual issues. We also tested to see if booklet completion was associated with communication outcomes at the 6-month follow-up. Multivariate findings indicate that the intervention significantly affected the frequency of general parent/child communication based on child reports. The intervention marginally affected frequency of parent/child communication about sexual issues based on parent reports. Booklet completion was associated with reduced discomfort discussing sex and was marginally associated with frequency of parent/child discussion of sex based on parent reports only. These findings indicate that a family-based program can have an impact on communication patterns. PMID:24094085

Casual Sexual Scripts on the Screen: A Quantitative Content Analysis.

While existing content analyses have provided insightful information in terms of contextual factors and frequency of sexual behaviors, not much is known about the relational context in which sexual depictions generally occur. The current study addresses this void by employing content analytic methods to measure the frequency and context of depictions of sexual behavior within nine popular television shows produced in the U.S., while taking into account the type of sexual behavior. The results suggest that, in the analyzed television shows, sexual behaviors within a casual sexual context were almost as frequently shown as sexual behaviors within a committed relationship context. Whereas sexual behaviors within a committed relationship context were mainly limited to passionate kissing, sexual behaviors within a casual sexual context mostly consisted of explicit portrayals of sexual intercourse. Additionally, genre seemed to be an important factor when examining casual sexual television content. The situational comedy genre, for example, had no explicit portrayals of intercourse and mainly portrayed kissing couples within a committed relationship. The comedy drama genre, on the contrary, had the largest proportion of explicit sexual portrayals, usually between casual sexual partners. A second goal of this study was to analyze the portrayals of the typical casual sexual experience script and the typical casual sexual relationship script in which these sexual behaviors often occur. For instance, our analyses revealed that female characters were more likely to initiate casual sex compared to male characters. Moreover, casual sex often occurred between former partners.

Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity.

This study compared influences from the mass media (television, music, movies, magazines) on adolescents' sexual intentions and behaviors to other socialization contexts, including family, religion, school, and peers. A sample of 1011 Black and White adolescents from 14 middle schools in the Southeastern United States completed linked mail surveys about their media use and in-home Audio-CASI interviews about their sexual intentions and behaviors. Analysis of the sexual content in 264 media vehicles used by respondents was also conducted. Exposure to sexual content across media, and perceived support from the media for teen sexual behavior, were the main media influence measures. Media explained 13% of the variance in intentions to initiate sexual intercourse in the near future, and 8-10% of the variance in light and heavy sexual behaviors, which was comparable to other contexts. Media influences also demonstrated significant associations with intentions and behaviors after all other factors were considered. All contextual factors, including media, explained 54% of the variance in sexual intentions and 21-33% of the variance in sexual behaviors. Adolescents who are exposed to more sexual content in the media, and who perceive greater support from the media for teen sexual behavior, report greater intentions to engage in sexual intercourse and more sexual activity. Mass media are an important context for adolescents' sexual socialization, and media influences should be considered in research and interventions with early adolescents to reduce sexual activity.

Clinical report--the evaluation of sexual behaviors in children.

Most children will engage in sexual behaviors at some time during childhood. These behaviors may be normal but can be confusing and concerning to parents or disruptive or intrusive to others. Knowledge of age-appropriate sexual behaviors that vary with situational and environmental factors can assist the clinician in differentiating normal sexual behaviors from sexual behavior problems. Most situations that involve sexual behaviors in young children do not require child protective services intervention; for behaviors that are age-appropriate and transient, the pediatrician may provide guidance in supervision and monitoring of the behavior. If the behavior is intrusive, hurtful, and/or age-inappropriate, a more comprehensive assessment is warranted. Some children with sexual behavior problems may reside or have resided in homes characterized by inconsistent parenting, violence, abuse, or neglect and may require more immediate intervention and referrals.

There is a need to involve sexual partners when addressing sexual behavior of high-risk adolescent women. This study explored men's perceptions of their role in sexual relationships with adolescent women with a history of sexually transmitted infection (STI) and abuse. The AIDS risk reduction model was used to assess sexual risk behaviors of these men for development of cognitive behavioral risk reduction interventions for themselves and partner. Qualitative interviews were conducted with African and Mexican American men (n = 14; ages 18 to 21 years), recruited via adolescent women enrolled in a control-randomized trial of behavioral interventions for reduction of unintended pregnancy, abuse, substance use, and STI. Participants varied in their perceptions of personal susceptibility to STI or HIV, access to informational resources regarding sexual behavior, and level of adult support for safer sexual behavior. These men shared perceptions of inadequate sexual health preparation, including education concerning risk, ultimately contributing to adverse outcomes of sexual behavior.

Although early research and the popular press have characterized college men as universal beneficiaries of uncommitted sex, emerging research notes considerable variability in men's sociosexuality (i.e., uncommitted sexual beliefs, desires, and behaviors). This study examined how diversity in sociosexuality is tied to the ways in which attachment orientations, conformity to masculinity norms, and homosocial engagement (i.e., non-romantic same-sex bonds) are organized across individuals. Latent profile analysis of 495 college males (ages 17–25, 62% White, 83.5% Heterosexual) detected five subgroups: Fully Unrestricted (10% of sample; high on sociosexuality and conformity to masculinity norms); Cognitively Unrestricted (36%; comparable to Fully Unrestricteds, but low on sociosexual behavior), Fully Restricted (30%; opposite on all constructs when compared to Fully Unrestricteds); Avoidant (16%; similar to Fully Restricteds, but with greater attachment avoidance); and Discrepant (8%; above average on sociosexual behavior, but discordant within and across constructs). There were notable demographic, personality, and behavioral differences between the subgroups (e.g., nearly 50% of the Discrepants self-identified as sexual minorities, Fully Restricteds were the most religious, Avoidants were the most shy). Findings indicate that college men's sociosexuality is highly nuanced and suggest the need for additional work to understand how attachment, masculinity norms, and homosociality shape men's sexual relationships.

Adolescent sexual risk behavior can lead to serious health consequences, yet few investigations have addressed its neurodevelopmental mechanisms. Social neurocircuitry is postulated to underlie the development of risky sexual behavior, and response to social reward may be especially relevant. Typically developing adolescents (N=47; 18M, 29F; 16.3±1.4years; 42.5% sexual intercourse experience) completed a social reward fMRI task and reported their sexual risk behaviors (e.g., lifetime sexual partners) on the Youth Risk Behavior Survey (YRBS). Neural response and functional connectivity to social reward were compared for adolescents with higher- and lower-risk sexual behavior. Adolescents with higher-risk sexual behaviors demonstrated increased activation in the right precuneus and the right temporoparietal junction during receipt of social reward. Adolescents with higher-risk sexual behaviors also demonstrated greater functional connectivity between the precuneus and the temporoparietal junction bilaterally, dorsal medial prefrontal cortex, and left anterior insula/ventrolateral prefrontal cortex. The greater activation and functional connectivity in self-referential, social reward, and affective processing regions among higher sexual risk adolescents underscores the importance of social influence underlying sexual risk behaviors. Furthermore, results suggest an orientation towards and sensitivity to social rewards among youth engaging in higher-risk sexual behavior, perhaps as a consequence of or vulnerability to such behavior.

Mixed Emotions: An Incentive Motivational Model of Sexual Deviance.

PubMed

Smid, Wineke J; Wever, Edwin C

2018-05-01

Sexual offending behavior is a complex and multifaceted phenomenon. Most existing etiological models describe sexual offending behavior as a variant of offending behavior and mostly include factors referring to disinhibition and sexual deviance. In this article, we argue that there is additional value in describing sexual offending behavior as sexual behavior in terms of an incentive model of sexual motivation. The model describes sexual arousal as an emotion, triggered by a competent stimulus signaling potential reward, and comparable to other emotions coupled with strong bodily reactions. Consequently, we describe sexual offending behavior in terms of this new model with emphasis on the development of deviant sexual interests and preferences. Summarized, the model states that because sexual arousal itself is an emotion, there is a bidirectional relationship between sexual self-regulation and emotional self-regulation. Not only can sex be used to regulate emotional states (i.e., sexual coping), emotions can also be used, consciously or automatically, to regulate sexual arousal (i.e., sexual deviance). Preliminary support for the model is drawn from studies in the field of sex offender research as well as sexology and motivation research.

Childhood and adolescent sexual abuse has been associated with subsequent (adult) sexual risk behavior, but the effects of force and type of sexual abuse on sexual behavior outcomes have been less well-studied. The present study investigated the associations between sexual abuse characteristics and later sexual risk behavior, and explored whether gender of the child/adolescent moderated these relations. Patients attending an STD clinic completed a computerized survey that assessed history of sexual abuse as well as lifetime and current sexual behavior. Participants were considered sexually abused if they reported a sexual experience (1) before age 13 with someone 5 or more years older, (2) between the ages of 13 and 16 with someone 10 or more years older, or (3) before the age of 17 involving force or coercion. Participants who were sexually abused were further categorized based on two abuse characteristics, namely, use of penetration and force. Analyses included 1177 participants (n=534 women; n=643 men). Those who reported sexual abuse involving penetration and/or force reported more adult sexual risk behavior, including the number of lifetime partners and number of previous STD diagnoses, than those who were not sexually abused and those who were abused without force or penetration. There were no significant differences in sexual risk behavior between nonabused participants and those who reported sexual abuse without force and without penetration. Gender of the child/adolescent moderated the association between sexual abuse characteristics and adult sexual risk behavior; for men, sexual abuse with force and penetration was associated with the greatest number of episodes of sex trading, whereas for women, those who were abused with penetration, regardless of whether the abuse involved force, reported the most episodes of sex trading. These findings indicate that more severe sexual abuse is associated with riskier adult sexual behavior.

This study tests the following three hypotheses: 1) there is a direct association between consumption of sexually explicit media (SEM) depicting non-condom use and STI-related sexual risk behavior among men who have sex with men (MSM), 2) The association between SEM consumption and STI-related sexual risk behavior is mediated by men’s sexual self-esteem, and 3) the relationship between SEM consumption and sexual risk behavior is mediated by condom use self-efficacy. A cross-sectional, Internet-based survey on exposure to SEM and sexual behavior of 1,391 MSM in the USA was conducted in 2011. The results confirmed hypothesis 1 and 3 while hypothesis 2 was rejected. Accordingly, a significant association between the use of SEM picturing condom use and STI related sexual risk behavior among MSM was found. Likewise, we found that the association between the use of SEM and sexual risk behavior was mediated by condom use self-efficacy in an indirect path. However, SEM did not influence sexual risk behavior via sexual self-esteem. To promote STI prevention, the actors in SEM may be used as role models in managing condom use in sexual contexts.

People suffering from substance dependence suffer from various sexual dysfunctions and are at risk for indulging in various high-risk sexual behaviors and thus are vulnerable to acquire various infections such as HIV/AIDS and other sexually transmitted infections. The aim of the study was to evaluate the correlation between sexual dysfunction and high-risk sexual behavior in opioid-dependent men receiving buprenorphine and naltrexone maintenance therapy. Semi-structured questionnaire, brief male sexual functioning inventory and HIV-risk taking behavior scale was administered to a sample of 60 sexually active men, receiving buprenorphine (n = 30) and naltrexone (n = 30) maintenance therapy for opioid dependence. The main outcomes are correlation between severity of sexual dysfunction and HIV-risk taking behavior. The study results showed 83% of the men on buprenorphine and 90% on naltrexone reported at least one of the sexual dysfunction symptoms. There was a negative correlation between sexual dysfunction and HIV-risk taking behavior that suggest severe the dysfunction, higher the risk taking behavior. Significant correlation was present with overall sexual dysfunction and HIV-risk taking behavior (P = 0.028 and in naltrexone receiving group premature ejaculation versus HIV-risk taking behavior however, (P = 0.022, P < 0.05) there were no significant differences among both the groups except above findings. Conclusion was treatment is associated with sexual dysfunctions and HIV-risk taking behavior, which has clinical implication. Future research should explore this further using biochemical analyses.

Sexually transmitted infections (STIs) are a major public health problem in developing nations. Identification of risk factors can help in formulating effective strategies against them. The present study was conducted in a tertiary care hospital in North India over 1 year to identify the risk factors associated with STIs. A questionnaire-based cross-sectional case-control survey was conducted where participants answered questions on demographic details, sexual behavior, and awareness of STIs. Cases were patients with STIs whereas controls were randomly selected from healthy individuals accompanying patients with nonvenereal complaints attending our hospital. There were 106 cases and 64 controls. STI patients had sexual debut 2 years before controls. A higher proportion of STI cases had lower education, multiple sexual partners, lived separately from their partner, had nonregular partners, had protected sex in the last month, had sex under influence of alcohol/illicit drugs, sex in unstructured settings, and engaged in transactional sex, in comparison to controls ( P < 0.05). More cases were aware of the symptoms/preventive measures of STIs ( P < 0.001). On multivariate analysis, multiple sexual partners, sex under influence of alcohol/illicit drugs with nonregular partner, protected sex in the last month, and knowledge of preventive measures were found to be statistically associated with STIs ( P < 0.05). Our study identifies risk-behavior patterns in patients with STIs, which should be modified to reduce the burden of these diseases. Increasing the knowledge about STIs in these patients can translate into more common condom usage that lends support for strengthening sexual health programs at grass-root levels. The small size of the study population could have led to decreased power of the study to detect differences between cases and controls. The external validity of our results needs to be tested in different population groups involving larger sample sizes.

Despite the importance of reliable self-reported sexual information for research on sexuality and sexual health, research has not examined reliability of information provided by gay, lesbian, and bisexual (GLB) youths. Test-retest reliability of self-reported sexual behaviors, sexual orientation, sexual identity, and psychosexual developmental milestones was examined among an ethnically diverse sample of 64 self-identified GLB youths. Two face-to-face interviews were conducted approximately two weeks apart using the Sexual Risk Behavior Assessment Schedule for Homosexual Youths (SERBAS-Y-HM). Overall, the mean of the test-retest reliability coefficients was substantial for 6 of the 7 domains: lifetime sexual behaviors (M = .89), sexual behavior in the past 3 months (M = .96), unprotected sexual behavior in the past 3 months (M = .93), sexual identity (κ = .89), sexual orientation (M = .82), and ages of various psychosexual developmental milestones (M = .77). Inconsistent reliability was found for reports of sexual behaviors while using substances. A small number of gender differences emerged, with lower reliability among female youths in the lifetime number of same-sex partners. The overall findings suggest that a wide range of self-reported sexual information can be reliably assessed among GLB youths by means of interviewer-administered questionnaires, such as the SERBAS-Y-HM.

To investigate the sexual transmission behaviors among HIV-positive MSM population engaging in unprotected sexual behaviors, as well as the relationship with health conditions and partner notification. A total of 308 HIV-positive MSM participants engaged in unprotected sexual behaviors were recruited by "snowballing" sampling in Shanghai and Chengdu. The questionnaire covered such items as the time of HIV infection diagnosis, CD4⁺ T cells count, viral load, antiviral therapy, anxiety and depressive symptoms, sexual partner types and sexual behaviors in the past six months, disclosure to fixed sexual partners and casual sexual partners among others. Of the 308 participants surveyed, the report rate of those having at least one-time sexual transmission behaviors during the past 6 months was 70.1% (216/308). Participants who had primary sexual partners and casual sexual partners following their HIV infection diagnosis accounted for 89.0% (274/308) and 68.2% (210/308) respectively. Of the aforementioned participants, 59.1% (162/274) and 94.3% (198/210) respectively had not disclosed their HIV infection to primary and casual sexual partners. Of thoes who did not disclose their HIV infection to primary sexual partners, 91.9% (147/162) reported sexual transmission behaviors. Of thoes who did not disclose their HIV infection to casual sexual partners, 89.9% (178/198) continue sexual transmission. As found in a multi-factor analysis, the infection risk exposure of those with heterosexual sexual orientation and engagement in sexual transmission behaviors was six times higher than those with homosexual orientation (aOR = 5.896, 95% CI: 1.808-19.232). For those who did not, or partially disclose their HIV infection to male casual sexual partners or commercial sexual partners, the risk exposure of further transmission was 29 times and 19 times higher than those disclose it to their sexual partners (no disclosure: aOR = 28.957, 95% CI: 7.511-65.004; partial disclosure: aOR = 18.956, 95% CI: 6.995-57.417). The highest risk came from those who continue their sexual transmission behavior within six months of their HIV infection diagnosis; the lowest risk came from those continue such behavior more than one year and within two years of their diagnosis (aOR = 0.048, 95% CI: 0.033-0.788); such risk rose to some extent for those continue such behavior over two years of their diagnosis. Compared to those without antiviral therapy, participants with the therapy pose less risk in sexual transmission behaviors. More than two-thirds of HIV-positive MSM population who engage in unprotected sexual behaviors reported sexual transmission behaviors. In this regard, increasing antiviral therapy and promoting sexual partner disclosure constituted an effective strategy to minimize further transmission among HIV-positive MSM population. Intervention of sexual transmission behaviors should be addressed to those diagnosed of HIV infection within six months.

Sexual behavior at work: Fun or folly?

2009-01-01

Sexual behavior at work (e.g., sexual jokes and propositions) has been largely portrayed as offensive and harmful. The current research represents the first studies to test whether this is typically the case. Study 1 surveyed manufacturing and social service workers (N = 238) about their psychological well-being, work withdrawal, and exposure to sexual behavior at work. Respondents indicated how often they were exposed to different sexual behaviors and how much they enjoyed or were bothered by them. Study 2 surveyed university staff (N = 1,004) about their psychological well-being, drug use, feelings of being valued at work, and exposure to sexual behavior at work. Fifty-eight percent of employees in Study 1 were exposed to sexual behavior in the past 2 years; 40% of employees in Study 2 were exposed to sexual behavior in the past year. Some women and many men reported enjoying sexual behavior at work. Despite this, exposure to sexual behavior at work predicted negative employee work and psychological well-being, even for employees who said they enjoyed the experience.

Some research shows that sexual assault victimization is associated with increased engagement in risky sexual behavior (e.g., intercourse without use of a condom or contraceptives), whereas other research indicates sexual assault victimization is related to sexual aversion. The purpose of the current study was to examine whether posttraumatic stress symptoms, alcohol use, and sexual assertiveness mediated the relationship between adolescent/emerging adulthood sexual assault (ASA) and risky sexual behavior, and whether posttraumatic stress symptoms mediated the relationship between ASA and sexual aversion, among college women. A sample of 462 women from a Midwestern university completed online questionnaires assessing ASA, child sexual abuse (CSA), posttraumatic stress symptoms (i.e., intrusion, avoidance, hyperarousal, and dissociation), alcohol use, sexual assertiveness, risky sexual behavior, and sexual aversion. CSA was considered as a covariate in the mediation models. Results of mediation analyses showed that the relationship between ASA and risky sexual behavior with a new partner was partially mediated by greater alcohol use and lower sexual assertiveness and that the relationship between ASA and risky sexual behavior with a regular partner was partially mediated by greater alcohol use. Results of a model examining mediators of ASA and sexual aversion detected no significant mediators. Results suggest that college women with a history of ASA would benefit from psychoeducation on the effect of alcohol on sexual decision-making, as well as from sexual assertiveness skills training, to reduce potential risks associated with risky sexual behaviors, particularly with lesser known partners, including sexually transmitted infections and sexual revictimization.

Like many other social phenomena, prostitution is increasingly coordinated over the Internet. The online behavior affects the offline activity; the reverse is also true. We investigated the reported sexual contacts between 6,624 anonymous escorts and 10,106 sex buyers extracted from an online community from its beginning and six years on. These sexual encounters were also graded and categorized (in terms of the type of sexual activities performed) by the buyers. From the temporal, bipartite network of posts, we found a full feedback loop in which high grades on previous posts affect the future commercial success of the sex worker, and vice versa. We also found a peculiar growth pattern in which the turnover of community members and sex workers causes a sublinear preferential attachment. There is, moreover, a strong geographic influence on network structure—the network is geographically clustered but still close to connected, the contacts consistent with the inverse-square law observed in trading patterns. We also found that the number of sellers scales sublinearly with city size, so this type of prostitution does not, comparatively speaking, benefit much from an increasing concentration of people.

Children exhibiting sexual behavior have increasingly gained the attention of child welfare and mental health systems, as well as the scientific community. While a heterogeneous group, children with sexual behavior problems consistently demonstrate a number of problems related to adjustment and overall development. In order to appropriately intervene with these children, a comprehensive understanding of etiology is imperative. The overarching goal of the present paper is to review the extant research on mechanisms associated with the development of problematic sexual behavior in childhood within a developmental psychopathology framework. What is known about normative and nonnormative sexual behavior in childhood is reviewed, highlighting definitional challenges and age-related developmental differences. Further, the relationship between child sexual abuse and child sexual behavior problems is discussed, drawing attention to factors impacting this relationship. Risk factors for child sexual behavior problems, beyond that of sexual abuse, are also reviewed utilizing a transactional-ecological framework. Finally, we conclude with a discussion of implications of a developmental psychopathology perspective on problematic child sexual behaviors to inform future research and intervention efforts. Such implications include the need for attention to normative childhood sexual behavior, developmental sensitivity, and examinations of ecological domain in concert.

The Role of Sexual Health Professionals in Developing a Shared Concept of Risky Sexual Behavior and HIV Transmission

“Risky sexual behavior” accounts for the majority of new HIV infections regardless of gender, age, geographic location, or ethnicity. The phrase, however, refers to a relatively nebulous concept that hampers development of effective sexual health communication strategies. The purpose of this paper is to propose development of a shared conceptual understanding of “risky sexual behavior.” We reviewed multidisciplinary HIV/AIDS literature to identify definitions of risky sexual behavior. Both the linguistic components and the social mechanisms that contribute to the concept of risky sexual behaviors were noted. Risky sexual behavior was often defined in a subjective manner in the literature, even in the scientific research. We urge a paradigm shift to focus on explicit behaviors and the social context of those behaviors in determining HIV risk. We also propose a new definition that reduces individual biases and promotes a broader discussion of the degree of sexual risk across a diversity of behavioral contexts. Sexual health professionals can strengthen practice and research initiatives by operating from a concise working definition of risky sexual behavior that is broadly transferable and expands beyond a traditional focus on identity-based groups.

Adolescent women's daily academic behaviors, sexual behaviors, and sexually related emotions.

PubMed

Hensel, Devon J; Sorge, Brandon H

2014-12-01

Emerging literature suggests that the emotional and behavioral experience in young women's romantic/sexual relationships may link to their academic success. However, existing studies' reliance on retrospective and/or global measures prevents detailed understanding of how and when specific academic experiences link to specific relationship experiences and whether these associations could vary over different school days. Adolescent women (N = 387; 14-17 years at enrollment) were recruited from primary care adolescent clinics for a longitudinal cohort study of sexual relationships and sexual behavior. Participants provided daily diary information on academic behaviors, sexual emotions, and sexual behaviors. Chi-square and generalized estimating equation ordinal logistic or linear regression, respectively, assessed prevalence of sexual behaviors or differences in sexual emotions when academic behaviors did and did not occur. Young women's weekday reports of skipping school or failing a test were significantly linked to more frequent vaginal sex, less frequent condom use, and different levels of sexual emotions, on that same day. Our findings provide evidence that the emotional and behavioral experiences in young women's romantic/sexual relationships may impact young women's reaction to academic events.

Frontotemporal dementia (FTD) is characterized by a number of prominent behavioral changes. While FTD has been associated with the presence of aberrant or unusual sexual behaviors in a proportion of patients, few studies have formally investigated changes in sexual function in this disease. We aimed to systematically quantify changes in sexual behavior, including current symptoms and changes from prior diagnoses, in behavioral-variant (bvFTD) and semantic dementia (SD), compared to Alzheimer's disease (AD). Carers of 49 dementia patients (21 bvFTD, 11 SD, 17 AD) were interviewed using the Sexual Behavior and Intimacy Questionnaire (SIQ), a survey designed to assess changes in sexual function across multiple domains including initiating, level of affection, and aberrant or unusual sexual behavior. BvFTD patients show prominent hyposexual behavior including decreased affection, initiation, and response to advances by partners, and decreased frequency of sexual relations, compared to AD and to SD patients. The greatest changes in sexual behavior compared to pre-diagnoses were found in the bvFTD group with a 90-100% decrease in initiation, response, and frequency of sexual relations. Notably, aberrant or unusual sexual behavior was reported in a minority of bvFTD and SD patients and occurred in patients who also showed hyposexual behavior toward their partner. Overall loss of affection, reduced initiation of sexual activity, and responsiveness is an overwhelming feature of bvFTD. In contrast, aberrant or unusual sexual behavior is observed in the minority of bvFTD patients. The underlying pathophysiology of these changes likely reflects structural and functional changes in frontoinsular and limbic regions including the hypothalamus.

Examining attachment to God and health risk-taking behaviors in college students.

PubMed

Horton, Karissa D; Ellison, Christopher G; Loukas, Alexandra; Downey, Darcy L; Barrett, Jennifer B

2012-06-01

Drawing on insights from attachment theory, this study examined whether three types of attachment to God--secure, avoidant, and anxious--were associated with health-risk behaviors, over and above the effects of religious attendance, peer support, and demographic covariates, in a sample of 328 undergraduate college students. Contrary to prior theory, secure attachment to God is not inversely associated with recent alcohol or marijuana use, or substance use prior to last sexual intercourse. Instead, avoidant and anxious attachment to God are associated with higher levels of drinking; anxious attachment to God is associated with marijuana use; and avoidant attachment to God is associated with substance use prior to last sexual intercourse. These patterns are gender-specific; problematic attachment to God is linked with negative outcomes solely among men.

Technology-Facilitated Sexual Violence Victimization: Results From an Online Survey of Australian Adults.

2016-10-01

Online forms of sexual harassment and abuse as experienced by adults represent an emerging yet under-researched set of behaviors, such that very few studies have sought to estimate the extent of the problem. This article presents the results of an online survey of 2,956 Australian adult (aged 18 to 54 years) experiences of technology-facilitated sexual violence (TFSV) victimization. The prevalence of TFSV was analyzed in relation to a 21-item scale developed in accordance with prior conceptual research identifying multiple dimensions of TFSV including digital sexual harassment, image-based sexual abuse, sexual aggression and/or coercion, and, gender and/or sexuality-based harassment (including virtual sexual violence). Results revealed significant differences in lifetime TFSV victimization for younger (18-24) and non-heterosexual identifying adults. Lifetime TFSV victimization for men and women was not significantly different, though women were more likely to report sexual harassment victimization and men were more likely to report victimization through the distribution of non-consensual images, as well as gender and/or sexuality-based harassment. The authors conclude that although women and men report experiencing similar overall prevalence of TFSV victimization, the nature and impacts of those experiences differ in particular gendered ways that reflect broader patterns in both gender relations and "offline" sexual harassment.

The purpose of our review was to analyze the relationship between the use of geosocial networking phone apps and risk behaviors for HIV infection in men who have sex with men (MSM). The review was guided by the question: Does the use of geosocial networking apps to find sex partners increase risk behaviors for HIV infection by MSM? We searched the databases PubMed, Web of Science, CINAHL, and LILACS, considering primary studies published up to December 2015, without any time restraint. All 14 studies that met our search criteria analyzed sexual behaviors in relation to sociocultural and economic characteristics, number of partners, unprotected anal sex, drug use, HIV testing, risk management measures, and the presence of other sexually transmitted diseases. The results indicated that use of geosocial networking apps to find sex partners may lead to new patterns of behavior and relationships that place MSM at risk for HIV.

Body piercing and tattooing are accepted by a growing number of teenagers and young adults as a way of self-expressing. Some authors suggest association between body piercings/tattoos and early sexual initiation, higher number of sexual partners, or risky sexual behaviors. The aim of the study was to evaluate sexual behaviors among young adults with body modifications (BMs)--tattoos and piercings. One hundred twenty young healthy adults, ages between 20 and 35, were included in the population study. The study group was divided into three subgroups: controls (N = 60), adults with tattoos (N = 28), and adults with piercings (N = 32). The research instrument was a self-prepared questionnaire containing 59 questions assessing socioepidemiological parameters, sexual behaviors, incidents of sexual harassment in the past, and self-attractiveness evaluation, as well as questions concerning tattoos and piercings. Socioepidemiological variables and sexual behaviors were compared between subgroups. To assess and describe the correlation between having BM--tattoos and piercing--and sexual behaviors in the population of young adults by using the logistic regression model. Adults with BMs have had their first intercourse statistically earlier and were more sexually active compared with controls. There were no statically significant differences in sexual orientation, sexual preferences, engaging in risky sexual behaviors, frequency of masturbation, and history of sexual abuse between the groups. In contrast, the frequency of sexual intercourses was statistically higher and oral sex was more likely to be a dominant sexual activity in adults with BM compared with controls. The multivariate logistic model revealed that adults with BM were four times less likely to participate in religious practices and twice more likely to have early sexual initiation. Having BM is associated with early sexual initiation and more liberal attitudes toward sexual behaviors but not with engaging in risky sexual behaviors. © 2012 International Society for Sexual Medicine.

The development of effective policies and programs to prevent sexual coercion among young people requires thorough understanding of the diversity of coercive sexual experiences, patterns in such types of experiences, and similarities and differences between subgroups, especially by gender, in patterns of coercive sexual experiences and associations with potential vulnerability factors. The present online self-report study assessed a wide range of coercive sexual experiences and potential vulnerability factors among a sociodemographically diverse sample of 1,319 young people (16-25 years old) in The Netherlands. Findings confirm that sexual coercion comprises a diversity of experiences, with rates differing substantially across types of coercion. Latent class analysis revealed distinct patterns of coercive sexual experiences for young women and young men. Among young men, three patterns of experiences were found: no coercive sexual experiences, experience with verbal pressure, and experience with verbal pressure as well as coercion related to alcohol intoxication. Among young women, four patterns of coercive experiences were identified. In addition to the three patterns observed among young men, a fourth pattern encompassed experiences with verbal pressure as well as the use of force or violence. Higher numbers of sexual partners, lower levels of sexual refusal skills, and higher levels of token resistance were consistently associated with increased vulnerability. Findings illustrate the importance of communication skills and suggest that sexual communication training should be an integral part of sexuality education.

Introduction The influence of media portrayals of sexual attitudes and normative expectations of young people at a critical developmental stage is of public health concern. Objectives To examine the role of mass media and Internet utilization in shaping the sexual health attitudes and behaviors of young undergraduates in Osogbo metropolis, Osun State, Nigeria. Materials and methods In a descriptive cross-sectional study, 400 undergraduates were selected using a multistage random sampling technique. Four hundred and fifty pretested, semistructured questionnaires were distributed; of these, 400 were returned properly filled. Data were analyzed using SPSS statistical software version 16. Results Mean age of respondents ± standard deviation was 23.6±2.99 years. Most were aware of the various forms of mass media (>95%). Most (64.0%) respondents spent 1–5 hours watching television, daily, and most used the Internet often. About 38.3% and 24.2% of respondents used the Internet and radio/television, respectively, as sources of information on sexual issues. Most respondents used the Internet for school assignments (83.0%, n=332), electronic mail (89.0%, n=356), and for accessing sexually explicit materials (74.5%, n=298). Most of the respondents (73.5%) opined that the Internet has a bad influence on youths’ sexual behavior, although accessing the Internet for sexual material or movies was acceptable to 25.3% of them. Of the 226 respondents who had ever had sex, 226 (100%), 37 (16.4%), 31 (13.7%), and 10 (4.4%) practiced coitus, oral sex, masturbation, and anal sex, respectively; 122 (54.0%) always used condoms, whereas 90 (40.0%) never used condoms during sexual activity; 33 (14.6%) had had sex with commercial sex workers. Further analysis showed that those who were yet to marry (single) were less likely to be sexually experienced than those who were married (adjusted odds ratio [AOR] =0.075, 95% confidence interval [CI] =0.008–0.679), and those who said accessing the Internet for sexual material is not acceptable to them were also less likely to be sexually experienced than those to whom it was acceptable (AOR =0.043, 95% CI =0.016–0.122). Predictors of having multiple sexual partners include the sex of the respondent and the frequency of Internet use, with females (AOR =0.308, 95% CI =0.113–0.843) and those who rarely use the Internet less likely to have multiple sexual partners. Conclusion We conclude that uncontrolled exposure to mass media and Internet could negatively influence the sexual patterns and behavior of youths. PMID:24729737

The impact of delinquency on young adult sexual risk behaviors and sexually transmitted infections.

Youth in the juvenile justice system have increased sexual risk behavior and sexually transmitted infections (STI). However, research exploring the effect of self-reported delinquency on sexual risk behavior and STI is limited, and results vary depending on the populations studied. Therefore, we used nationally representative data to examine the longitudinal association between delinquent behavior, sexual risk behavior, and STI among adolescents and young adults. We used a sample of 10,828 participants from the National Longitudinal Study of Adolescent and Health. Outcomes included STI and sexual risk behavior from Wave III (17-27-year-olds). Predictors for the generalized linear regression models (stratified by gender) include race, age, education, relationship status at Wave III, and delinquent behavior groups (life-course persistent, adolescence-limited, late-onset and nondelinquency). None of the delinquency groups were associated with young adult STI. Only life-course persistent delinquency was associated consistently with sexual risk behavior (except for condom use). The adolescence-limited and late-onset groups had limited effects on sexual risk outcomes. Life-course persistent delinquency influences the expression of young adult sexual risk behavior. However, delinquent behavior does not predict STI in a population-based sample of youth. Programs and interventions that address the sexual health of youth need to consider the role of delinquency in shaping sexual risk behaviors, and future research should explore broader societal and environmental risk factors on STIs.

2012-01-01

Developmentally inappropriate sexual behavior has long been viewed as a possible indicator of child sexual abuse. In recent years, however, the utility of sexualized behavior in forensic assessments of alleged child sexual abuse has been seriously challenged. This article addresses a number of the concerns that have been raised about the diagnostic value of sexualized behavior, including the claim that when population base rates for abuse are properly taken into account, the diagnostic value of sexualized behavior is insignificant. This article also identifies a best practice comprehensive evaluation model with a methodology that is effective in mitigating such concerns.

Introduction: People suffering from substance dependence suffer from various sexual dysfunctions and are at risk for indulging in various high-risk sexual behaviors and thus are vulnerable to acquire various infections such as HIV/AIDS and other sexually transmitted infections. AIM: The aim of the study was to evaluate the correlation between sexual dysfunction and high-risk sexual behavior in opioid-dependent men receiving buprenorphine and naltrexone maintenance therapy. Materials and Methods: Semi-structured questionnaire, brief male sexual functioning inventory and HIV-risk taking behavior scale was administered to a sample of 60 sexually active men, receiving buprenorphine (n = 30) and naltrexone (n = 30) maintenance therapy for opioid dependence. Results: The main outcomes are correlation between severity of sexual dysfunction and HIV-risk taking behavior. The study results showed 83% of the men on buprenorphine and 90% on naltrexone reported at least one of the sexual dysfunction symptoms. There was a negative correlation between sexual dysfunction and HIV-risk taking behavior that suggest severe the dysfunction, higher the risk taking behavior. Significant correlation was present with overall sexual dysfunction and HIV-risk taking behavior (P = 0.028 and in naltrexone receiving group premature ejaculation versus HIV-risk taking behavior however, (P = 0.022, P < 0.05) there were no significant differences among both the groups except above findings. Conclusion: Conclusion was treatment is associated with sexual dysfunctions and HIV-risk taking behavior, which has clinical implication. Future research should explore this further using biochemical analyses. PMID:26257480

A meta-analysis of the relations between three types of peer norms and adolescent sexual behavior

2018-01-01

The aim of the present meta-analysis was to investigate the associations between three types of peer norms–descriptive norms (peer sexual behaviors), injunctive norms (peer sexual attitudes), and peer pressure to have sex–and two adolescent sexual behavior outcomes (sexual activity and sexual risk behavior). Adolescent sexual activity was more strongly associated with descriptive norms (ESrfixed = .40) than with injunctive norms (ESrfixed = .22) or peer pressure (ESrfixed = .10). Compared with the sexual activity outcome, the effect size for descriptive norms (peer sexual risk behavior) for sexual risk behavior was smaller (ESrfixed = .11). Age, gender, peer type, and socio-cultural context significantly moderated these associations. Additional analyses of longitudinal studies suggested that selection effects were stronger than socialization effects. These findings offer empirical support for the conceptual distinction between three types of peer norms and hold important implications for theory, research, and intervention strategies.

Pre- and postnatal bisphenol A treatment results in persistent deficits in the sexual behavior of male rats, but not female rats, in adulthood.

PubMed

Jones, Bryan A; Shimell, Jordan J; Watson, Neil V

2011-02-01

Perinatal administration of the endocrine disruptor bisphenol A (BPA) reportedly inhibits the sexual behavior of sexually naïve adult male rats. In order to evaluate the effects of BPA administration during early development on later reproductive behavior, we administered one of five doses of bisphenol A daily to pregnant female rats throughout gestation and lactation, and quantified the appetitive and consummatory sexual behaviors of the resultant male and female offspring over multiple sexual encounters in adulthood. Males receiving low dose perinatal BPA (50 μg/kg bw/day) showed persistent deficits in sexual behavior in adulthood. Males receiving the highest dose (5 mg/kg bw/day), however, were indistinguishable from controls with respect to consummatory sexual behaviors but showed decreased latencies to engage in those behaviors when sexually naïve, with significant non-linear, or U-shaped, dose-response relationships observed on the first and last day of testing. Adult female sexual behavior was not affected by early BPA administration at any dose tested. These results are consistent with previous reports that BPA exerts behavioral effects especially at low doses, and further indicates that BPA can cause lasting impairment of sexual behavior in males, but does not alter the normal development of female appetitive or consummatory sexual behaviors. To our knowledge, this is the first report indicating that adult sexual performance is impaired in sexually experienced animals following perinatal exposure to bisphenol A.

Studies concerning behaviorally bisexual men continue to focus on understanding sexual risk in according to a narrow range of sexual behaviors. Few studies have explored the subjective meanings and experiences related to bisexual men’s sexual behaviors with both male and female partners. In-depth, semi-structured interviews were conducted with 75 men who engaged in bisexual behavior within the past six months. Participants were asked about their subjective sexual experiences with male and female partners. Findings suggest adherence to normative gender roles, with attraction to men and women conforming to these stereotypes, as well as a segregation of sexual behaviors along gendered lines. Overall, condom use was influenced by perceptions of potential negative consequences. Based on these findings, it remains critical that public health and other social and behavioral sciences continue to study bisexual men’s sexual health issues as separate and distinct from their exclusively homosexual and heterosexual counterparts.

Is risky sexual behavior continuous or categorical? A taxometric analysis of the Sexual Risk Survey.

PubMed

Marcus, David K; Fulton, Jessica J; Turchik, Jessica A

2011-03-01

Risky sexual behaviors are behaviors that involve the possibility of an adverse outcome, such as contracting a sexually transmitted infection or unwanted pregnancy. The question of whether risky sexual behavior exists as a discrete class (i.e., taxon) or as a dimensional construct has not previously been explored. The authors performed a set of taxometric analyses on 4 factor scales derived from the Sexual Risk Survey (Turchik & Garske, 2009) with data from 1,103 college students. The results provided consistent support for a dimensional latent structure in which variations in reported risky sexual behavior reflect differences in degree and not differences in kind. The implications of these findings for the assessment of risky sexual behavior are discussed.

[Childhood sexual behavior as an indicator of sexual abuse: professionals' criteria and biases].

PubMed

González Ortega, Eva; Orgaz Baz, Begoña; López Sánchez, Félix

2012-01-01

Some sexual behaviors are related to child sexual abuse experiences, but none unequivocally. Therefore, professionals might use non-empirical-based criteria and be biased when detecting and reporting victims. To check this hypothesis, we presented 974 Spanish and Latin American professionals from different fields (Psychology, Education, Health, Social Services, Justice, and Police Force) with hypothetical situations of child sexual behavior (varying the sex, age and behavior) by using an experimental vignette method based on Factorial Survey. Participants were asked to indicate whether such behaviors are a sign of abuse and whether they would report them. We also measured demographic, academic, professional and attitude factors. According to the analysis, professionals' suspicion of abuse is more affected by personal factors, whereas their reporting intention depends more on situational factors. The main criterion adopted is the type of sexual behavior, with professionals being more likely to suspect and report in response to aggressive sexual behavior and precocious sexual knowledge. Professionals' attitudes to sexuality seem to generate biases, as those who are erotophobic are more likely to suspect abuse. None of the sexual behaviors was seen as evidence of abuse.

Sexual orientation measurement and chronic disease disparities: National Health and Nutrition Examination Survey, 2009-2014.

To examine chronic disease disparities by sexual orientation measurement among sexual minorities. We pooled data from the 2009-2014 National Health and Nutrition Examination Survey to examine differences in chronic disease prevalence between heterosexual and sexual minority people as defined by sexual identity, lifetime sexual behavior, 12-month sexual behavior, and concordance of lifetime sexual behavior and sexual identity. Self-identified lesbian women reported greater odds of asthma (adjusted odds ratio [aOR], 3.19; 95% confidence intervals [CI], 1.37-7.47) and chronic bronchitis (aOR, 2.64; 95% CI, 1.21-5.72) than self-identified heterosexual women. Self-identified sexual minority women with a history of same-sex sexual behavior reported greater odds of arthritis (aOR, 1.67; 95% CI, 1.02-2.74). Compared with heterosexual men, gay men reported greater odds of chronic bronchitis when sexual orientation was defined by sexual identity (aOR, 4.68; 95% CI, 1.90-11.56) or 12-month sexual behavior (aOR, 3.22; 95% CI, 1.27-8.20), as did bisexual men defined by lifetime sexual behavior (aOR, 2.36; 95% CI, 1.14-4.89). Bisexual men reported greater odds of asthma when measured by lifetime sexual behavior (aOR, 1.90; 95% CI, 1.12-3.19), as did self-identified heterosexual men with a history of same-sex sexual behavior (aOR, 2.21; 95% CI, 1.10-4.46). How we define sexual orientation influences our understanding of chronic disease prevalence. Capturing subgroups of sexual minority people in health surveillance is essential for identifying groups most at risk and developing targeted interventions to reduce chronic disease disparities.

Predicting risky sexual behavior in emerging adulthood: examination of a moderated mediation model among child sexual abuse and adult sexual assault victims.

PubMed

Littleton, Heather L; Grills, Amie E; Drum, Katherine B

2014-01-01

Although having a sexual victimization history is associated with engaging in sexual risk behavior, the mechanisms whereby sexual victimization increases risk behavior are unclear. This study examined use of sex as an affect regulation strategy as a mediator of the relationship between depressive symptoms and sexual risk behavior among 1,616 sexually active college women as well as examined having a history of child sexual abuse (CSA), adolescent/adult sexual assault (ASA), or both (CSA/ASA) as moderators. Results supported the mediated model as well as moderated mediation, where depressive symptoms were more strongly associated with use of sex as an affect regulation strategy among ASA victims, and sex as an affect regulation strategy was more strongly related to sexual risk behavior for CSA/ASA victims.

Descriptive study involving semistructured interviews and unstructured narratives. A parent study of self-neglect characteristics. Cognitively intact, self-neglecting older adults referred from 11 community-based senior services agencies (N = 69). Interviews included a comprehensive psychiatric assessment using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis-I and II Disorders and an unstructured interview that allowed subjects to describe important elements of their life stories. Content analysis was used to identify personal experiences and behavior patterns in each subject's narrative. Four types of traumatic personal experiences (psychologically traumatic loss, separation or abandonment (29%); violent victimization, physical trauma, or sexual abuse (19%); exposure to war or political violence (9%); prolonged mourning (7%)) and five behavior patterns (significant financial instability (23%), severe lifelong mental illness (16%), mistrust of people or paranoia (13%), distrust and avoidance of the medical establishment (13%), substance abuse or dependence (13%)) were identified in the life stories. Patterns of traumatic personal experiences and maladaptive behaviors that self-neglecters frequently report were identified. Experiences, perceptions, and behaviors developed over a lifetime may contribute to elder self-neglect. Further exploration and better understanding of these patterns may identify potential risk factors and areas for future targeted screening, intervention, and prevention. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Mental health and school adjustment problems are thought to distinguish early sexual behavior from normative timing (16-18 years), but little is known about how early sexual behavior originates from these problems in middle-childhood. Existing studies do not allow for co-occurring problems, differences in onset and persistence, and there is no information on middle-childhood school adjustment in relationship to early sexual activity. This study examined associations between several middle-childhood problems and early sexual behavior, using a subsample (N = 4,739, 53 % female, 98 % white, mean age 15 years 6 months) from a birth cohort study, the Avon Longitudinal Study of Parents and Children. Adolescents provided information at age 15 on early sexual behavior (oral sex and/or intercourse) and sexual risk-taking, and at age 13 on prior risk involvement (sexual behavior, antisocial behavior and substance use). Information on hyperactivity/inattention, conduct problems, depressive symptoms, peer relationship problems, school dislike and school performance was collected in middle-childhood at Time 1 (6-8 years) and Time 2 (10-11 years). In agreement with previous research, conduct problems predicted early sexual behavior, although this was found only for persistent early problems. In addition, Time 2 school dislike predicted early sexual behavior, while peer relationship problems were protective. Persistent early school dislike further characterized higher-risk groups (early sexual behavior preceded by age 13 risk, or accompanied by higher sexual risk-taking). The study establishes middle-childhood school dislike as a novel risk factor for early sexual behavior and higher-risk groups, and the importance of persistent conduct problems. Implications for the identification of children at risk and targeted intervention are discussed, as well as suggestions for further research.

To assess the impact of prenatal cocaine exposure (PCE) on adolescent sexual risk behaviors. Externalizing behavior, teen substance use, and early sexual intercourse were examined as pathways mediating the effects of PCE on sexual risk behaviors. Adolescents (N=364; 185 PCE, 179 non-cocaine exposure (NCE); 205 girls, 159 boys), primarily African-American and of low socioeconomic status, were prospectively enrolled in a longitudinal study at birth. Risky sexual behaviors were assessed at ages 15 and 17. Externalizing behavior at 12 years was assessed with the Youth Self-Report. Substance use, via self-report and biologic assays, and early (before age 15) sexual intercourse were assessed at age 15. Path analyses with the weighted least squares estimator with mean and variance adjustments were performed. The final structural equation model-based path model, χ(2)=31.97 (df=27), p=.23, CFI=.99, TLI=.99, RMSEA=.021, WRMR=.695, indicated a direct effect of PCE on sexual risk behavior (β=.16, p=.02). Although PCE was related to greater externalizing behavior (β=.14, p=.009), which in turn, predicted early sexual intercourse (β=.16, p=.03), leading to sexual risk behavior (β=.44, p<.001), bootstrapping indicated a non-significant indirect effect (β=.01, p>.10). Substance use was correlated with early sexual intercourse (r=.60, p<.001) and predicted sexual risk behavior by age 17 (β=.31, p=.01). Prenatal cocaine exposure was related to more engagement in sexual risk behaviors, suggesting the importance of reducing substance use among pregnant women as a means of prevention of offspring substance use and sexual risk behavior.

BACKGROUND Research has examined how physical and sexual intimate partner violence (IPV) victimization increases sexual risk behavior, yet research is lacking on 1) the effect of psychological IPV on sexual risk behavior and 2) factors through which psychological IPV may be linked to sexual risk behavior. METHODS The current study examined the relationship between psychological IPV and sexual risk behavior controlling for other forms of IPV (i.e., physical and sexual) in a sample of 186 HIV-negative community women currently experiencing IPV. Further, this study examined the potential mediating effects of four posttraumatic stress disorder (PTSD) symptom severity clusters (i.e., re-experiencing, avoidance, numbing, and hyperarousal) on this relationship. FINDINGS Results revealed that greater severity of psychological IPV was uniquely and directly related to greater sexual risk behavior. Additionally, of the four PTSD symptom severity clusters, only avoidance symptom severity mediated the relationship between psychological IPV and sexual risk behavior. CONCLUSION Implications for addressing psychological IPV and PTSD to improve women’s sexual health outcomes are discussed. PMID:25498762

Though research indicates a complex link between substance use and sexual risk behavior, there is limited research on the association between sexual risk behavior and prescription drug misuse. In light of alarming increases in prescription drug misuse and the role of demographic characteristics in sexual risk behavior and outcomes, the current study examined demographic differences (gender, sexual identity, age, relationship status, parental class background, and race/ethnicity) in sexual risk behavior, sexual behavior under the influence of prescription drugs, and sexual risk behavior under the influence of prescription drugs in a sample of 402 young adults (ages 18 to 29) who misused prescription drugs. Nearly half of the sexually active young adult prescription drug misusers in this sample reported recent sex under the influence of prescription drugs; more than three-quarters reported recent sex without a condom; and more than one-third reported recent sex without a condom after using prescription drugs. Zero-inflated Poisson regression models indicated that White race, younger age, higher parental class, and being a heterosexual man were all associated with sexual risk behavior, sex under the influence of prescription drugs, and sexual risk under the influence of prescription drugs. Findings have implications for the targeting of prevention and intervention efforts.

Little is known about the relationship between personality and sexual development among mid-adolescents. In the current study, we used a person-centered approach to investigate the relation between personality types and the development of sexual behavior. We hypothesized that undercontrolling adolescents would engage in more advanced, casual, and risky sexual behavior compared to their resilient and overcontrolling peers. Data were used from 407 mid-adolescents (Mage = 14.5) followed across four measurement waves spanning 18 months. Results from latent class analyses (LCA) identified the three classical personality types: resilients, undercontrollers, and overcontrollers. Controlling for perceived pubertal timing and biological sex, latent growth curve analyses in Mplus showed that, at baseline, undercontrollers were more sexually experienced and engaged in more casual and risky sexual behavior than resilients and overcontrollers. Although initial levels of sexual behavior differed by personality types, over time increases in sexual behavior occurred at a similar rate across the types. Overall, the current study showed that undercontrolling adolescents are early sexual developers who engage in more advanced, casual, and risky sexual behavior than other adolescents. The implications of these findings for longer-term differences in sexual behavior between personality types in later adolescence are discussed.

Alcohol consumption is associated with sexual behavior and outcomes, though research indicates a variety of moderating factors, including demographic characteristics. To better target interventions aimed at alcohol-related sexual risk behavior, our analyses simultaneously examine demographic predictors of both day- and event-level associations between alcohol consumption and sexual behavior in a sample of young adults (N = 301) who are sexually active and consume alcohol. Young adults (aged 18-29) recruited using time-space sampling and incentivized snowball sampling completed a survey and a timeline follow-back calendar reporting alcohol consumption and sexual behavior in the past 30 days. On a given day, a greater number of drinks consumed was associated with higher likelihood of sex occurring, particularly for women and single participants. During a given sexual event, number of drinks consumed was not associated with condom use, nor did any demographic predictors predict that association. Findings highlight associations between alcohol and sexual behavior, though not between alcohol and sexual risk behavior, highlighting the need for additional research exploring the complex role of alcohol in sexual risk behavior and the need to develop prevention efforts to minimize the role of alcohol in the initiation of sexual encounters.

Although research has increasingly emphasized how adolescent sexual behavior may be associated with aspects of health beyond unwanted pregnancy and sexually transmitted infections, no current theoretical or conceptual model fully explains associations between sexual behavior and multiple facets of health. We provide a conceptual model that explicates possible processes of how adolescent sexual behavior may influence physical, mental, and social health. Next, we review the current literature consistent with this conceptual model, demonstrating that although early sexual behavior can be associated with some negative outcomes, sex may be, on average, a positive experience in late adolescence. Finally, we discuss important future directions for research in these areas, including how individuals' attitudes about and perceptions of sexual behavior influence outcomes of sex. © 2014 Wiley Periodicals, Inc.

Childhood sexual abuse (CSA) is associated with sexual risk behavior in adulthood, but little research has investigated processes that might mediate this relation. The purpose of this study was to investigate whether constructs suggested by the traumagenic dynamics (TD) model (a theory of the effects of CSA) or constructs suggested by the Information-Motivation-Behavioral skills (IMB) model (a theory of the antecedents of sexual risk behavior) better mediated the relation between CSA and sexual risk behavior in adulthood. Participants were 481 women attending an STI clinic (66% African American) who completed a computerized survey as well as behavioral simulations assessing condom application and sexual assertiveness skills. Forty-five percent of the sample met criteria for CSA and CSA was associated with sexual risk behavior in adulthood. In multiple mediator models, the TD constructs mediated the relation between CSA and the number of sexual partners whereas the IMB constructs mediated the relation between CSA and unprotected sex. In addition, the TD constructs better mediated the relation between CSA and the number of sexual partners; the TD and IMB constructs did not differ in their ability to mediate the relation between CSA and unprotected sex. Sexual risk reduction interventions for women who were sexually abused should target not only the constructs from health behavior models (e.g., motivation and skills to reduce sexual risk), but also constructs that are specific to sexual abuse (e.g., traumatic sexualization and guilt).

Animal Models in Sexual Medicine: The Need and Importance of Studying Sexual Motivation.

Ventura-Aquino, Elisa; Paredes, Raúl G

Many different animal models of sexual medicine have been developed, demonstrating the complexity of studying the many interactions that influence sexual responses. A great deal of effort has been invested in measuring sexual motivation using different behavioral models mainly because human behavior is more complex than any model can reproduce. To compare different animal models of male and female behaviors that measure sexual motivation as a key element in sexual medicine and focus on models that use a combination of molecular techniques and behavioral measurements. We review the literature to describe models that evaluate different aspects of sexual motivation. No single test is sufficient to evaluate sexual motivation. The best approach is to evaluate animals in different behavioral tests to measure the motivational state of the subject. Different motivated behaviors such as aggression, singing in the case of birds, and sexual behavior, which are crucial for reproduction, are associated with changes in mRNA levels of different receptors in brain areas that are important in the control of reproduction. Research in animal models is crucial to understand the complexity of sexual behavior and all the mechanisms that influence such an important aspect of human well-being to decrease the physiologic and psychological impact of sexual dysfunctions. In other cases, research in different models is necessary to understand and recognize, not cure, the variability of sexuality, such as asexuality, which is another form of sexual orientation.
