The acquisition of basic sex information

Previously unpublished data from the Kinsey sample concerning the acquisition of basic sex information are presented. These are contrasted to data obtained from a similar, but smaller sample of respondents from the current generation. Basic facts about sex are being learned at considerably younger ages today, apparently as a result of increased maternal effort to provide information, increased sex education in the schools, and more explicit treatment of sex in the media. Same‐sex peers remain the dominant educators, but other sources, notably mothers, have increased in importance. The sex differences in age of acquisition found in the Kinsey sample have largely disappeared.     

The Science of Orgasm Has Finally Come: A Review of: “The Science of Orgasm. By Barry R. Komisaruk,Carlos Beyer-Flores,and Beverly Whipple.”

This research sought to examine psychologically mediated effects of differential penis size. To investigate this issue, we asked male and female undergraduates (N = 284) to read erotic passages that differed only in the length of the penis that was ascribed to the male protagonist—3 in. long (small), 5 in. long (medium), 8 in. long (large), or no mention made of penis size (control condition). Arousal and attributional responses to these portrayals were then assessed. In addition, subjects' erotophobia‐erotophilia (their disposition to respond to erotic stimuli with negative to positive emotions) and their level of prior sexual experience were assessed. Results showed that the erotic passages were significantly arousing and that the manipulation of perceptions of penis size was highly effective. Despite the effectiveness of the manipulation, however, subjects did not report differential arousal or (for the most part) attributional responses to depictions of small, medium, or large penises. Correlational analyses revealed that erotophilic (versus erotophobic) persons may be more aroused by depictions of a large penis, and more sexually experienced males seemed to be more aroused by depictions of medium than by small or large penises. In all cases, however, the observed correlations were modest. Overall, the findings suggest that, for most individuals, penis size may be as unimportant on a psychological level as it appears to be on a physical level.     

Perceived Prevalence and Definitions of Sexual Dysfunction as Predictors of Sexual Function and Satisfaction

Evidence for the influence of sexual beliefs on sexual functioning and satisfaction has mainly emanated from clinical lore. Empirical investigations on this topic remain sparse. This study investigated whether beliefs regarding prevalence and definitions of male and female sexual dysfunctions predicted sexual function and satisfaction in a sample of 131 undergraduate students. Results indicated that higher perceived prevalence of male and female sexual dysfunctions was predictive of lower sexual functioning and poorer sexual satisfaction in women. For the male participants, none of the examined sexual beliefs emerged as significant predictors of their sexual functioning or satisfaction. Surprisingly, it was also found that participants estimated the prevalence of female sexual dysfunctions to be higher than male sexual dysfunctions, while defining male sexual dysfunctions more broadly than female sexual dysfunctions. Possible mechanisms for the findings are provided.     

Birth Cohort Differences in Sexual Identity Development Milestones Among HIV-Negative Gay and Bisexual Men in the United States

The coming-out process for gay and bisexual men (GBM) involves crossing sexual identity development (SID) milestones: (1) self-awareness of sexual attraction to the same sex, (2) self-acceptance of an identity as gay or bisexual, (3) disclosure of this sexual identity to others, and (4) having sex with someone of the same sex. We examined trends in SID milestones by birth cohort in a 2015 U.S. national sample of GBM (n = 1,023). Birth cohort was independent of when men first felt sexually attracted to someone of the same sex (median age 11 to 12). However, with the exception of age of first same-sex attraction, older cohorts tended to pass other milestones at later ages than younger cohorts. Latent class analysis (LCA) of SID milestone patterns identified three subgroups. The majority (84%) began sexual identity development with same-sex attraction around the onset of puberty (i.e., around age 10) and progressed to self-identification, same-sex sexual activity, and coming out—in that order. The other two classes felt same-sex attraction during teen years (ages 12.5 to 18.0) but achieved the remaining SID milestones later in life. For 13% of men, this was during early adulthood; for 3% of men, this was in middle adulthood. Findings highlight the need to monitor ongoing generational differences in passing SID milestones.     

Heterogeneity in Gender/Sex Sexualities: An Exploration of Gendered Physical and Psychological Traits in Attractions to Women and Men

Sexuality research has generally privileged attractions based on partners’ sexed physical bodies over attractions based on other features, including gender expression and personality traits. Gender may actually be quite central to sexual attractions. However, its role has received little empirical attention. To explore how gendered and sexed features, among others, are related to sexual attractions, the current study assessed how sexually diverse individuals described their attractions to feminine, masculine, and gender-nonspecific features of women and men. A sample of 280 individuals responded to the open-ended questions: “What do you find attractive in a man?” and “What do you find attractive in a woman?” We coded responses as pertaining to physical and/or psychological features, and as being gendered masculine, feminine, or gender-nonspecific. Our analyses showed that participants named gender-nonspecific features most frequently in responses to both questions, feminine features more than masculine features in attractions to women, and masculine features more than feminine features in attractions to men. Additionally, participants named feminine physical features more than masculine physical features, and masculine psychological features more than feminine psychological features, both in their attractions to women and overall. These results highlight the importance of considering attractions based on gender, rather than sex alone.
