If clitoral stimulation caused orgasm with a lover, women would have no reason to offer intercourse and the human race would die out. Kinsey and Hite were the only researchers to promote the role of the clitoris in female orgasm. However, even researchers refer vaguely to clitoral stimulation without specifying the stimulation technique or the precise anatomy. Kinsey noted that few men offer any foreplay. Women rarely insist on it.
