Pompoir is a sexual technique in which the woman uses her vaginal muscles to stimulate the man's penis.[1][2][3][4][5] Both partners remain still, while the woman strokes the man's erection using rhythmic, rippling pulses of the pubococcygeus muscles, so this practice is best performed in a woman on top position.
Performing Kegel or pelvic floor exercises can increase a woman's skill in pompoir by strengthening the relevant muscles, and allows her to identify, and isolate, individual muscles, to contract them in turn to provide the rippling sensation.[1][2]
