Women who achieve stimulation through penile vaginal intercourse achieve climax more easily with men with larger penis, according to a study published in The Journal of Sexual Medicine. This is attribute to the ability of a longer penis to stimulate the complete length of the vagina and the cervix.

In another study, 75 women were shown 33 3D models of penis of different shapes and sizes. It was found that for one-time encounters, women preferred an average penis length of 6.4 inches. In long term relationships, the preferred penis length on average was 6.4 inches. It was also found that women tend to look for longer at larger penises.
