Without the protection of reliable contraception, few women would volunteer for unprotected intercourse. The idea that women have a sex drive to be impregnated is ludicrous. Women offer sex to a man who supports their family goals and who, hopefully, provides loving companionship. The receiver of intercourse can never have an orgasm because the stimulation of intercourse only lasts as long as a man has an erection. Specifically, the stimulation of intercourse does not continue until the receiver's orgasm.
