Concerns about genital appearance are unique compared to other concerns about physical appearance. While not as common of a concern as body weight, muscularity, amount of head hair and body hair, or height, penis size was a concern for 68.3% of 200 men in one study.

These first estimates of erect penis size preferences using 3D models suggest women accurately recall size and prefer penises only slightly larger than average.īoth men and women often have reported discomfort with the appearance of their genitals. 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. Women recalled model size accurately using this method, although they made more errors with respect to penis length than circumference.

Women ( N = 75) selected amongst 33, 3D models. 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.

Studies of women’s penis size preferences typically have relied on their abstract ratings or selecting amongst 2D, flaccid images. Women’s preferences for penis size may affect men’s comfort with their own bodies and may have implications for sexual health.
