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.     

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.

Body Movement Is Associated With Orgasm During Vaginal Intercourse in Women

Very few studies have investigated the relationship between women’s ability to experience an orgasm during vaginal intercourse and specific stimulation techniques. We examined two common techniques during vaginal intercourse both with and without simultaneous external clitoral stimulation: (1) body movement, in particular back-and-forth swinging movements of the pelvis and trunk; and (2) precise rubbing of the clitoris with an immobilized body. Structural equation modeling was used to compare the effects of the two stimulation techniques on women’s orgasm frequency (N = 1,239). As hypothesized, the frequency of orgasm during vaginal intercourse with simultaneous clitoral stimulation was positively associated with a preference for body movement during arousal. Body movement, as opposed to body immobilization, was also associated with a higher frequency of orgasm during vaginal intercourse without simultaneous clitoral stimulation. We conclude that body movement is associated with more orgasms during vaginal intercourse, whereas precise rubbing of the clitoris with an immobilized body is not associated with more orgasms. Teaching women to move their pelvis and trunk in a swinging back-and-forth movement during vaginal intercourse might therefore facilitate reaching an orgasm, whereas encouraging them to self-stimulate the clitoris might be less helpful if done with an immobilized body.     

The Relationship Between Sexual Concordance and Orgasm Consistency in Women

Sexual concordance (the relationship between genital and self-reported sexual responses) may be associated with orgasm consistency (OC; the proportion of sexual acts leading to orgasm) during penile–vaginal intercourse (PVI) in women. We investigated the relationship between women’s sexual concordance (assessed using different stimulus modalities and self-reported sexual arousal methods) and OC during various sexual activities (assessed using different types of questions). For Study 1 (n = 51), when sexual concordance was assessed using audiovisual sexual stimuli, we did not find a statistically significant relationship between OC and poststimulus self-reports of sexual arousal or genital sensations, raw values of OC, or ranges of OC. For Study 2 (n = 44), where sexual concordance was assessed using audionarrative sexual stimuli, we did find a statistically significant relationship between PVI OC and sexual concordance using change in self-reported sexual arousal, and ranges of orgasm consistency. Two findings were inconsistent with previous research. First, OC varied significantly by activity type in both studies; masturbation yielded the highest OC. Second, PVI OC was significantly related to oral sex and masturbation OC (Study 2). We discuss the need for further research and various factors that may affect women’s orgasm consistency and sexual concordance.     

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.

Prostitution and fellatio

Questionnaires gathered from men arrested while trying to hire female prostitutes in three Western cities indicate that the desire for fellatio is an important reason clients seek female prostitutes. Respondents were more likely to select fellatio than any other practice when asked which sexual practices they (a) had ever experienced with a prostitute (81% in comparison to 55% for vaginal sex; N = 995), (b) usually experienced with a prostitute (51% in comparison to 12% for vaginal sex, the second most common practice; N = 926), and (c) experienced during their most recent sexual encounter with a prostitute (68% in comparison to 43% for vaginal sex; N = 424). Though a majority of respondents (65%) found the practice of fellatio very appealing, an even greater proportion expressed that opinion about vaginal intercourse (76%; N = 55). These findings, when analyzed in the context of other research on sexual practices, suggest that the desire for fellatio may be one reason some men seek prostitutes.     

Recalling sexual behavior: A methodological analysis of memory recall bias via interview using the diary as the gold standard

This study examined the effect of time lag on the validity of retrospective self‐reports of sexual behavior. Seventy‐five heterosexual students (44 women, 31 men) made daily recordings of sexual behavior, condom use, and alcohol or substance use for 1 month. Ability of respondents to recall sexual behavior recorded during this period was assessed at 1, 2, and 3 months after diary completion using recall interviews (25 interviewed at each interval). For vaginal intercourse, total recall error was significantly greater at 3 months than at 1 month post‐diary. For all other variables assessed, the 2‐ and 3‐month time intervals did not produce significant increases in total recall error. Higher frequency of vaginal intercourse, orgasm, and alcohol use prior to sexual activity were associated with total recall error for some but not all behaviors and outcomes. The results provide a partial validation of the diary‐interview recall model as a method for studying recall error.

Parenting Practices and Adolescent Sexual Behavior: A Longitudinal Study

The effects of parental attitudes, practices, and television mediation on adolescent sexual behaviors were investigated in a study of adolescent sexuality and media (N = 887). Confirmatory factor analyses supported an eight‐factor parenting model with television mediation factors as constructs distinct from general parenting practices. Logistic regressions indicated that adolescents reporting greater parental disapproval and limits on viewing at Wave 1 were less likely to initiate oral sex between Waves 1 and 2. Adolescents who reported more sexual communication with parents were more likely to initiate oral sex. Results for vaginal intercourse were similar to those for oral sex. Coviewing was a significant negative predictor of initiation of sexual behavior. Parental attitudes and television mediation can delay potentially risky adolescent sexual behaviors.     

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.     

Sexual behavior of clients with street prostitutes in Camden,NJ

This paper describes the sexual behaviors of 101 male clients with female street prostitutes. An earlier study (Freund, Leonard, & Lee, 1989) was limited to sexual behaviors of street prostitutes themselves. Interviews were given by 62% of the clients approached. The clients were mature men (mean = 39.8 years), long‐term residents of Camden, NJ (mean = 19.2 years), and currently or previously married (78/101). Racial composition was similar to the general population of the area, 65% white, 33% black, 2% Asian. Clients reported a mean of 5.3 years of using prostitution, with 81% having been clients of Camden prostitutes for more than a year. Most were regular (or repeat) clients; 93% monthly or more frequently, and 63% weekly or more frequently. About one‐half (55%) reported sex with the same prostitute or same small group of prostitutes. The primary meeting place was the street (78/101) and 43% of the sexual encounters took place in the clients' cars. Ejaculation into the vagina was most frequently reported (43/101), followed by ejaculation into the mouth (39/101) Reports of condom use were substantial; 72% for vaginal and 33% for oral intercourse (mean = 58% of encounters).     

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.

Virginity Lost,Satisfaction Gained? Physiological and Psychological Sexual Satisfaction at Heterosexual Debut

Despite the literature's focus on (hetero)sexual initiation, little is known about the degree to which young people are satisfied by their first vaginal intercourse experience, let alone the factors that predict satisfaction. This study analyzed data from a cross-sectional survey of 1,986 non-Hispanic White and Black 18- to 25-year-old respondents from four university campuses. Respondents were asked to rate the degree to which their first vaginal intercourse was physiologically and psychologically satisfying. Both Black and White women were significantly less likely than Black and White men to experience considerable or extreme satisfaction at first vaginal intercourse, particularly physiological satisfaction. Among all four gender–race groups, being in a committed relationship with one's sexual partner greatly increased psychological satisfaction, particularly among women. Experiencing less guilt at first sexual intercourse was also strongly associated with psychological satisfaction for women. Developing sexual relationships with partners they care for and trust will foster satisfaction among young people at first vaginal intercourse. These findings highlight strong gender asymmetry in affective sexual experience.     

Prevalence and Motivations of Vaginal Practices in Tete Province,Mozambique

ABSTRACT. Vaginal practices have been linked with an increase in risk for HIV transmission and other harms. In 2007, a household survey of 919 women was conducted in Tete province, Mozambique, as part of the World Health Organization Multicountry Study on Gender, Sexuality, and Vaginal Practices. Women aged 18 to 60 years old were interviewed to determine prevalence and motivations for vaginal practices. A large range of frequently used practices was identified. Nearly 80% of women reported three or more current practices, and virtually all had used at least three practices in their lifetime. Elongation of the vaginal labia minora was universal (99% of women), while a quarter stated they had made small vaginal cuts or incisions at least once. Ninety-two percent of women also reported ever use of intravaginal cleansing, and insertion of substances in the vagina was practiced by 72%. Around half (48%) reported ingestion of substances to affect the vagina, mostly to heat, tighten, or loosen the vagina. Application of substances on the genitalia (16%) and steaming (15%) were less popular. To prepare for sexual intercourse, women reported products were commonly applied, ingested, inserted, or steamed. Pregnancy, delivery, and postpartum were also associated with ingestion (26%), steaming (39%), and cutting (32%). Adoption of microbicides and condom use may be influenced by vaginal practices. HIV-prevention messages and interventions, including future microbicides, need to take into account the high prevalence of vaginal practices and motivations for their use. Further attention needs to be given to potentially harmful practices in HIV-prevention efforts in Mozambique.     

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.
