Qualitative research to date has focused on the contexts surrounding anal intercourse in South Africa ( 16, 17) and Brazil ( 18, 19), but there is a dearth of research on American women’s experiences with anal intercourse. A topic that has received even scarcer attention is the circumstances under which women engage in anal intercourse. A number of researchers have already pointed to the need for increased attention to anal intercourse as an understudied source of HIV transmission from seropositive men to their seronegative female partners ( 1, 3, 6, 13). This oversight may be due to cultural taboos surrounding anal intercourse, including its association with homosexuality and its perceived lack of hygiene ( 1). Most studies of heterosexual HIV transmission fail to distinguish between vaginal and anal intercourse in their assessments of coital acts, thus continuing to overlook anal intercourse as a potential source of HIV transmission. Additionally, Halperin ( 1) found that women who engaged in anal intercourse were less likely to use condoms during anal intercourse than during vaginal intercourse. ![]() Similarly, in Brazil, researchers found that seronegative women who practiced anal intercourse in addition to vaginal and/or oral intercourse with seropositive male partners were approximately four times as likely to acquire HIV than women who did not practice anal intercourse ( 15). For example, a New York study of initially serodiscordant, heterosexual couples found that a history of anal intercourse was one of the strongest predictors of eventual HIV transmission, adjusted OR = 10.81, 95% CI = 2.78–42.0 ( 14). Given that anal intercourse is associated with higher rates of heterosexual HIV transmission than vaginal intercourse ( 10– 13), women who engage in unprotected anal intercourse with sexual partners of unknown or seropositive status may be at greater risk for acquiring HIV than women who do not practice anal intercourse or who use protection while doing so. Prior studies that examined the prevalence of sexual behaviors among women and included anal intercourse found that 20–30% of US women reported lifetime rates of anal intercourse ( 3, 5– 7) and 19%–32% of US women reported having had anal sex in the last 6–12 months ( 8, 9). Nevertheless, there is evidence to suggest that anal intercourse is also widely practiced by women in the US ( 1– 4). Although much scholarly attention has been paid to anal intercourse between men who have sex with men, research on women’s experiences of anal sex has been scarce.

The study, which was conducted at UCLA's Sexual Psychophysiology and Affective Neuroscience (SPAN) Laboratory, has not yet been published in a peer-reviewed journal.įollow Rachael Rettner Follow Live Science, Facebook & Google+. "For men who are considering surgery to increase their phallus sizes, maybe they do not have to after all, if women tend to overestimate" the size of a penis they've seen, Leung said. This finding may be reassuring to men who are self-conscious about their penis size, the researchers said. They were then asked to pick that same model from a bin of 33 models, either immediately or after completing a 10-minute survey (to allow time to pass).Īfter completing the 10-minute survey, women tended to overestimate the size of the penis they had previously examined, the study found. In a second part of the new study, women were given one of the penis models and allowed to examine it for 30 seconds. The new study, on the other hand, is the first to use 3D printed models, which meant women could physically handle them, Leung said. ![]() However, many past studies have relied on images, or used terms such as "small," "medium" and "large" when gauging women's penis preferences, and these terms may have different meanings to different people, Leung said. ![]() Contact me with news and offers from other Future brands Receive email from us on behalf of our trusted partners or sponsors By submitting your information you agree to the Terms & Conditions and Privacy Policy and are aged 16 or over.
