Patterns of Sexual Experience Among Urban Latino and African American Ninth Grade Students

This analysis assessed patterns of sexual experience, the order in which behaviors were initiated, and associated factors, among Latino and African American ninth grade students (average age 15.2) who self-administered audio-computer-assisted surveys on netbooks in classes at 10 Los Angeles–area public high schools. Lifetime experiences with vaginal and oral sex were most common (19% and 16%, respectively); fewer reported anal sex (6%). Of the 23% reporting any sex, 91% fell into four categories: 36% reporting both oral and vaginal sex; 23% vaginal only; 18% all three; and 13% oral only. Most sexually experienced students (88%) initiated with vaginal or oral sex (46% vaginal, 33% oral, 9% both same day). No dominant pathway of sexual onset emerged for those reporting all three types of sex. We found no evidence that oral or anal sex substituted for or delayed vaginal sex. Males, those with a current partner, and those reporting multiple partners were more likely than others to report all three sexual behaviors versus vaginal only (odds ratios [ORs] 2.0, 1.5, 3.0; p = .02, .06, < .01, respectively). Although vaginal intercourse dominated their early sexual behavior, one-fifth of sexually experienced students reported anal intercourse, highlighting the need for specific prevention messages surrounding this higher-risk behavior.     

EFFECTS OF OVERWEIGHT ON RISKY SEXUAL BEHAVIOR OF ADOLESCENT GIRLS

We use data from the National Longitudinal Survey of Adolescent Health to estimate effects of adolescent girls' overweight on their propensity to engage in risky sexual behavior. We estimate single equation, two‐stage, and sibling fixed‐effects models. We consider both absolute weight and weight relative to other girls in the individual's school. We focus on vaginal intercourse without a condom, any type of sexual activity while under the influence of alcohol, and anal intercourse. Our findings confirm previous research indicating that overweight or obese girls are less likely than their recommended‐weight counterparts to be sexually active. As a result, they are less likely to have vaginal intercourse without a condom. However, overweight or obese girls are not less likely to have sex under the influence of alcohol, and once they have had vaginal intercourse, their consistency of condom use is no different from that of their recommended‐weight peers. The most striking finding is that overweight or obese girls are at least 15% more likely than their recommended‐weight peers to have ever had anal intercourse regardless of whether they have ever had vaginal sexual intercourse. The results from this study underscore the importance of using multifaceted and contemporary measures of risky sexual behavior and have implications for the health and well‐being of adolescent girls.

The lesbian dyad

Little is known regarding how respondents interpret terms that are commonly used in sexual behavior surveys. The present study assessed the impact of four factors on respondents’ judgments of whether the hypothetical actors “Jim” and “Susie “ would consider a particular behavior that they had engaged in to be “sex.” The four factors were respondent's gender, actor's gender, type of act (vaginal, anal, or oral intercourse), and who achieved orgasm (neither, Jim only, Susie only, or both). Two hundred twenty‐three undergraduates (22.2 ± 2.2 years; 65% female) were asked to read 16 scenarios featuring Jim and Susie and to judge whether each actor would consider the described behavior to be sex. Results indicated that vaginal and anal intercourse were considered sex under most circumstances. Whether oral intercourse was labeled as sex depended on the gender and viewpoint of the actor, and whether orgasm occurred. Findings suggest that items in sexual behavior surveys need to be clearly delineated to avoid subjective interpretations by respondents.     

Identifying the Causal Pathways from Religiosity to Delayed Adolescent Sexual Behavior

This study used the Integrative Model as a framework to examine whether religiosity delays onset of coitus among a longitudinal sample of virgins, and investigated the causal pathways of this relationship. In addition, this study examined the behavioral beliefs about the consequences of engaging in sex, which distinguishes between youth who vary in level of religiosity. A further analysis was also conducted to examine whether religiosity offers protective effects in terms of progression toward sexual intercourse on a sexual behavior index. The sexual behavior index assumes a progressive nature of sexual behaviors, and includes the following seven behaviors: kissing, having breasts touched (touching for boys), genital touching, receiving oral sex, vaginal intercourse, giving oral sex, and receiving (or giving) anal sex. Religiosity at baseline was negatively associated with sexual debut one year later. This relationship was mediated through attitudes toward personally engaging in sexual intercourse. Religiosity at baseline was also negatively associated with scores on the sexual behavior index one year later. These results suggest that religiosity offers protective effects for both coital and noncoital sexual behaviors.

Sexual practices at last heterosexual encounter and occurrence of orgasm in a national survey

In order to examine factors associated with orgasm in heterosexual encounters, we analyzed data from the Australian Study of Health and Relationships, a national telephone survey of sexual behavior and attitudes and sexual health knowledge carried out in 2001-2002 with a representative sample of 19,307 Australians aged 16 to 59. Respondents were asked whether at their last sexual encounter they gave or received manual stimulation and oral sex, had vaginal intercourse or anal intercourse, and whether they had an orgasm. Vaginal intercourse was the dominant practice: 95% of encounters included it. Of the 64 possible combinations of these practices, 13 account for 93% of encounters: vaginal intercourse alone (12%), vaginal + manual stimulation of the man's and/or woman's genitals (49%), and vaginal intercourse + manual + oral (32%). Encounters may also have included other practices. Men had an orgasm in 95% of encounters and women in 69%. Generally, the more practices engaged in, the higher a woman's chance of having an orgasm. Women were more likely to reach orgasm in encounters including cunnilingus. This is the first large-scale empirical study worldwide to link specific practices with orgasm. Demographic and sexual history variables were comparatively weakly associated with orgasm.     

Sexual practices and the duration of last heterosexual encounter: findings from the Australian longitudinal study of health and relationships

This study investigated the association between sexual practices and duration of a sexual encounter. Using data from a population-based computer-assisted telephone survey of 8,656 Australians aged 16 to 64 years, four distinct patterns of sexual practices among respondents were found: "basic sexual encounter" (involving mainly kissing, cuddling, stroking one's partner and being stroked, and vaginal intercourse), "basic sexual encounter plus oral sex," "all assessed sexual practices" (all sexual behaviors included in the survey), and "mainly vaginal intercourse" (characterized by lower levels of kissing, cuddling, and stroking). For both men and women, respondents classified in the basic sexual encounter plus oral sex, and all assessed sexual practices clusters reported significantly longer durations than those in the basic sexual encounter group, whereas respondents in the mainly vaginal intercourse cluster reported shorter durations. These differences were found even after allowing for demographic differences in sexual duration-specifically, age and partner type of the most recent opposite-sex partner. These findings add to the understanding of what typically happens in a sexual encounter. Overall, longer sexual encounters appear to be associated with the inclusion of the least common sexual practices-namely, oral sex and self-stimulation.     

Correlates of Oral Sex and Vaginal Intercourse in Early and Middle Adolescence

This study examined whether a comprehensive set of psychosocial factors was equally predictive of both adolescent vaginal intercourse and oral sex among 1,105 adolescents aged 12–16. Logistic regressions were used to examine the relationships between parental communication, religiosity, bonding to school, heavy drinking, sex expectancies, normative beliefs, and both oral sex and vaginal intercourse. Age, gender, bonding to school, heavy drinking, and negative health expectancies predicted both oral sex and vaginal intercourse. Parental communication was associated with vaginal intercourse but not oral sex. Behavior‐specific normative beliefs were differentially associated with oral and vaginal sex.     

Forced Sexual Experiences and Sexual Situation Self‐Efficacy Among South African Youth

Nearly 20% of South African youth experience forced or coerced sexual intercourse. Understanding the factors associated with forced sex is important for informing prevention programs aimed at reducing sexual violence and HIV and AIDS. Multilevel regression models test the association between sexual situation self‐efficacy and forced sex among 2,893 South African adolescents. Findings suggest that youth are more likely to experience forced sex after periods of time when their levels of self‐efficacy are lower than their average levels of self‐efficacy. Furthermore, youth who are lower on their self‐efficacy compared to their peers are more likely to experience forced sex. Implications for prevention research are discussed.     

Condom use among Latino college students

Recent reports indicate that Latinos, the largest racial/ethnic minority group in the United States, are disproportionately affected by HIV and AIDS. College health professionals, therefore, should understand current sexual behaviors and risk factors among Latino youth. The authors assessed students' condom use at their most recent sexual encounter by using data from those students who reported oral, vaginal, or anal sex during the last 30 days. Fewer than half of recently sexually active Latino students had used condoms during their last oral (4.9%), vaginal (41.3%), or anal (27.8%) sexual encounter. Predictors of condom use varied according to the type of sexual activity. Findings from this exploratory study offer current information about condom use and sexual behaviors among Latino college students and suggest that prevention interventions and messages should be tailored to students' gender and types of sexual activity.     

Physical Abuse in Early Childhood and Transition to First Sexual Intercourse among Youth in Cape Town,South Africa

This study examined the relationship of physical abuse in early childhood and timing of first sexual intercourse among young South Africans aged 14 to 22 in Cape Town. Using the Cape Area Panel Survey and applying log-normal models, time ratios were estimated to show how rapidly or slowly youth experience first sexual intercourse. Results indicated that boys who experienced physical abuse in early childhood had faster timing to first sex. Boys and girls with violent school environments had faster timing to first sex. Race moderated the effects of physical abuse. Compared to Blacks, Coloreds who experienced higher levels of physical abuse in early childhood had faster timing to first sex. Youth with greater knowledge about HIV/AIDS and those with greater risk perception of contracting HIV/AIDS delayed first sex. On the basis of these findings, policy makers are encouraged to consider the early childhood experiences of youth when designing policies toward HIV/AIDS prevention in South Africa.

Examining the influence of gender and sexual motivation in college hookups

ABSTRACT

Objective: Hooking up is common in college, and has been linked to heavy drinking. Hookups have positive as well as negative consequences, and thus the motivations for hooking up are complex. Yet, little research has focused on these motivations. The present study examined the role that gender and drinking patterns play in the relationship between sexual motivation and penetrative hookups. Participants: Heavy drinking college students (N = 396) completed online surveys between September/October 2009. Method: Sexual motivation, alcohol, and hooking up were assessed. Results: Enhancement motives and drinking frequency predicted more frequent oral and vaginal sex when hooking up, while peer and partner motives predicted anal sex. Men endorsed greater enhancement motives, peer motives, and hookup oral and vaginal sex. For men, coping motives predicted oral and vaginal sex and peer motives predicted anal sex. Conclusions: Results provide greater insight into the reasons why college students engage in penetrative hookups.     

The Relationship Between Cognitive Ability and Experiences of Vaginal,Oral, and Anal Sex in the United States

Few studies have investigated the sexual development of populations with low cognitive abilities in the United States. This article examines the relationship between cognitive ability and various sexual experiences from adolescence (ages 12 to 18) to early adulthood (ages 28 to 34). Data were from 13,845 respondents interviewed at Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), a probability sample of adolescents in the United States followed from adolescence to adulthood. Adjusted logistic regression models were used to study relationships between cognitive ability, approximated by the Add Health Picture Vocabulary Test (AHPVT), and experiences of vaginal, oral, and anal sex. After controlling for biological sex, age, race/ethnicity, and socioeconomic status (SES), individuals in the lowest cognitive ability group had significantly lower odds of experiencing each type of sex than those in the average ability group. Although individuals in the highest cognitive ability group had significantly lower odds of experiencing vaginal intercourse than those in the average ability group, this association did not remain significant when analyses were stratified by biological sex. These differences in experiences have implications for future health and warrant further study to understand policy implications for sexual health services and education.     

The Association Between Sexual Behavior and Affect: Moderating Factors in Young Women

Sexual behavior is associated with increased positive affect and decreased negative affect. However, contextual variables such as partner type, behavior type, and condom use may moderate these associations. The goal of the present research was to examine these contextual moderators using monthly longitudinal data from a sample of young women. Female first-year college students (N = 477) completed monthly assessments of their sexual behaviors and positive and negative affect. Participants reported more negative affect in months in which they engaged in sexual behavior compared to months in which they did not. This association was moderated by partner type, such that only sexual behavior with casual partners was associated with increased negative affect. Participants reported more positive affect during months with kissing/touching only compared to months without sexual behavior; however, this association did not differ significantly from the association between oral/vaginal sex and positive affect. Condom use did not moderate the association between vaginal sex and positive or negative affect. In this sample of young women transitioning to college, engaging in sexual behavior was generally associated with negative affect; however, changes in affect depended on partner type and sexual behaviors. Findings have implications for sexual health education.     

Adaptive training for existing male transsexual gender role: A case history

The development of AIDS interventions for adolescents is hindered by the lack of data on the conditions that influence high‐risk sexual behavior. We examined psychosocial correlates of condom use and multiple partner sex for a sample of sexually‐active heterosexual adolescent women. Respondents reported higher levels of vaginal intercourse than the “average” adolescent. A minority were engaging in anal intercourse. Condom use was associated with perceived enjoyment of condoms and communication skills. Number of sexual partners was associated with susceptibility beliefs, social norms, and sexual communication skills. The findings support the general observation that AIDS interventions with adolescents should build sexual communication skills, address motivational issues, and teach people how to enjoy safe‐sex activities.     

Sexual Practices and the Duration of Last Heterosexual Encounter: Findings from the Australian Longitudinal Study of Health and Relationships

This study investigated the association between sexual practices and duration of a sexual encounter. Using data from a population-based computer-assisted telephone survey of 8,656 Australians aged 16 to 64 years, four distinct patterns of sexual practices among respondents were found: “basic sexual encounter” (involving mainly kissing, cuddling, stroking one's partner and being stroked, and vaginal intercourse), “basic sexual encounter plus oral sex,” “all assessed sexual practices” (all sexual behaviors included in the survey), and “mainly vaginal intercourse” (characterized by lower levels of kissing, cuddling, and stroking). For both men and women, respondents classified in the basic sexual encounter plus oral sex, and all assessed sexual practices clusters reported significantly longer durations than those in the basic sexual encounter group, whereas respondents in the mainly vaginal intercourse cluster reported shorter durations. These differences were found even after allowing for demographic differences in sexual duration—specifically, age and partner type of the most recent opposite-sex partner.

Overall, longer sexual encounters appear to be associated with the inclusion of the least common sexual practices—namely, oral sex and self-stimulation.     

Heterosexual Women’s Anal Sex Attitudes and Motivations: A Focus Group Study

Focus group methods were used to explore heterosexual women’s receptive anal sex attitudes and motivations. Behaviors under investigation included penile–anal intercourse (PAI), manual–anal stimulation, oral–anal contact, and the use of sex toys. A total of 33 self-identified heterosexual women ages 18 to 30 recruited from two metropolitan areas in the Midwestern United States participated in one of six focus groups. The findings suggest that women viewed heterosexual anal sex as an emerging norm. Attitudes and motivations were complex and varied by behavior. Dominant themes included curiosity, pain, pleasure, and stigma. Relational factors, including acquiescence, coercion, and consent, were also salient among participants. Factors that influence anal sexual behaviors may not be entirely distinct from those that influence other sexual behaviors; however, factors that influence anal intercourse may be distinct from those that influence nonintercourse anal sex. Improved understanding will allow scientists to better understand the integration of anal sex behaviors into the broader sexual repertoire.     

An Episodic Analysis of Substance Use and Risky Sexual Behavior in a Racially Diverse Sample of Young Men Who Have Sex with Men

Many studies have examined the relations between drug use and sexual behaviors; however, few have utilized episodic data to examine the co-occurrence of both behaviors within the same episode. This study surveyed 403 racially and ethnically diverse gay, bisexual, and other young men who have sex with men (YMSM; ages 18–29) in New York City. Men were surveyed about their sexual behavior and concurrent use of illicit substances and alcohol during their most recent sexual encounter with their main and/or casual partner(s). Logistic regression models were built to analyze predictors of unprotected oral and anal intercourse with main and casual partners. Results suggest that use of inhalant nitrates and alcohol increased the odds of men engaging in unprotected receptive anal intercourse (URAI) and men who identified as middle or high socioeconomic status (SES) were at lower odds of engaging in URAI with their main partner. Use of other illicit substances was not associated with unprotected sexual intercourse. These findings indicate a need to further consider the role of licit substances used by YMSM as a means of further reducing the incidence of HIV infection in this population. In addition, the high rates of unprotected anal intercourse among men reporting a main partner has the potential to be a significant source of HIV risk, and should be further explored among YMSM.     

Heterosexual Women’s and Men’s Labeling of Anal Behaviors as Having “Had Sex”

This study explored labeling of penile–anal intercourse (PAI), manual–anal (MA), and oral–anal (OA) behaviors as having “had sex” among heterosexual men and women with such experience residing in the United States (n = 3,218). Adult men and women completed an online questionnaire assessing sexual behaviors and whether each counted as having had sex. With the exception of anal intercourse, there was high variation in whether a behavior was labeled having had sex. There was not consensus on which anal sexual behaviors constituted having had sex, with attitudes varying across age, gender, and behavioral experience. Those who were older, male, and had the specific behavioral experience were more likely to label it as having had sex. Behaviorally specific assessments of the various anal behaviors as part of the sexual repertoire is critical to more accurate evaluation of sexual histories and assessment of risks to sexual health.
