Researchers at the University of New Mexico and the University of California conducted the ground breaking study that revealed what size women prefer their partners to have.
75 women were given 33 3D printed phallic objects, each of different sizes. They were asked to pick what would be perfect for a long-term relationship and a one night stand.
The average length women preferred for a long-term relationship was 6.3 inches and 6.4 for a one night stand.
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.
“Novelty itself contributes to pleasure, so seeking a more novel-sized penis may be consistent with a goal to pursue pleasure primarily in one-time partners,” the researchers said.
“Women may prefer a smaller penis size in a long-term partner compared to a one-time partner for reasons of both physical comfort and a preference for less masculinity in a longer term partner.”
