From 3D-printed penis models, women (N=41) chose their favored penis girths and lengths for different durations of sexual relations. They preferred larger-girth (but not longer-length) models for one-time partners than for longer-term partners. Women's sexual selection may help explain why human penises are unusually thick compared to other primates.
