Evidence to suggest that women's sexual behavior is influenced by hip width rather than waist-to-hip ratio

Waist-to-Hip Ratio Predicts Sexual Perception and Responses to Sexual Assault Disclosures

The current work investigates the effects of target of perception's waist-to-hip ratio (WHR) on perceivers' judgments of sexual unrestrictedness and sexual victimization prototypicality. Studies 1a and 1b found that women with lower WHRs were perceived as relatively more sexually unrestricted. Studies 2a and 2b found that women with lower WHRs were perceived as relatively more prototypic of sexual victimization. Study 3 built on these findings to consider implications for responses to sexual assault disclosures. Perceivers disbelieved and minimized a disclosure of assault relatively more when made by a woman with a higher WHR. In sum, this body of work implicates WHR as a body cue that can inform consequential sexual perception. Thereby, this work identifies factors that could influence judgments of credibility of sexual violence reports, which may have implications for hesitancy to report sexual violence.

Women's Preferences for Penis Size: A New Research Method Using Selection among 3D Models

Women's preferences for penis size may affect men's comfort with their own bodies and may have implications for sexual health. Studies of women's penis size preferences typically have relied on their abstract ratings or selecting amongst 2D, flaccid images. This study used haptic stimuli to allow assessment of women's size recall accuracy for the first time, as well as examine their preferences for erect penis sizes in different relationship contexts. Women (N = 75) selected amongst 33, 3D models. Women recalled model size accurately using this method, although they made more errors with respect to penis length than circumference. Women preferred a penis of slightly larger circumference and length for one-time (length = 6.4 inches/16.3 cm, circumference = 5.0 inches/12.7 cm) versus long-term (length = 6.3 inches/16.0 cm, circumference = 4.8 inches/12.2 cm) sexual partners. These first estimates of erect penis size preferences using 3D models suggest women accurately recall size and prefer penises only slightly larger than average.
