Pompoir

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.^{[citation needed]}

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]

The technique is also called the Singapore grip.^[6][7] The title of The Singapore Grip, a novel by J. G. Farrell, as well as its 2020 television adaptation, refers to this phrase.^[8]
