Abstract

Women’s preferences for pen1s size may affect men’s comfort with their own bodies and may have implications for sexual health.

Studies of women’s pen1s 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 pen1s 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 pen1s length than circumference. Women preferred a pen1s 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 pen1s size preferences using 3D models suggest women accurately recall size and prefer pen1ses only slightly larger than average.

Guardian, Monday 1 August 2016

The purpose of the euphoric sensation of the female orgasm has long perplexed scientists, as it is not necessary for conception, and is often not experienced by women during sex itself. Now researchers in the US say they might have found its evolutionary roots. Human female orgasm, they say, might be a spin-off from our evolutionary past, when the hormonal surges that accompany it were crucial for reproduction.
