I don't know what men like Alan want women to be. Celibate until they are past childbearing? Single mothers? Have perfectly effective birth control? The most realistic answer is perfectly effective birth control, well it gets quite close but not to 100%, and the best birth control costs a bunch of money. It's the right that has opposed most of these things: single motherhood and providing such mothers adequate financial support, widely available free birth control for all etc.. Oh heterosexual men in general probably oppose women all becoming celibate. I may speak for myself but us women would be pretty happy enjoying cake in lieu of sex thank you very much. You have no idea how little we think about sex, at any age.
