3D modeling and simulation study of clitoral stimulation in 12 sexual positions

Abstract

A notable disparity exists in orgasm frequency during sex between heterosexual men and women, with many heterosexual women unable to reach orgasm through vaginal intercourse alone. The clitoris is essential for female arousal and orgasm, with its glans sensitive to light touch, friction, pressure, and vibration, while other parts respond to stretch, pressure, and displacement. Factors that may increase orgasm frequency, especially in women, are not well understood. This study aims to evaluate stimulation of female erogenous structures during common sexual positions by recording pelvic movements in a standard male–female couple. Using CAD models with attributed tissue properties, we simulated the pressure exerted on the vagina and clitoris to predict potential clitoral stimulation across positions. Data from these recordings were integrated with 3D pelvic and sexual organ simulations to assess how various positions affect clitoral stimulation.
