Men, who like foreplay as a means of extending their own arousal, assume that women must orgasm from the stimulation they provide. But no one had heard of the clitoris until Kinsey highlighted its role in female masturbation. Couples did not discover female orgasm by themselves. Men were told to include clitoral stimulation in their foreplay. But clitoral stimulation has never been associated with heterosexual lovemaking. It has been (and still is) associated with lesbianism and female masturbation. There is no research to indicate that women orgasm from clitoral stimulation with a lover.
