I think the sexual revolution, beneficial as it was in many ways, came with the implication that this was true: men and women are alike in their feelings about sex — that the male view was shared by everyone. We coerced ourselves, often unconsciously, to feel that we should feel “liberated.” But our “powerful instinctive forces” say not true. Just as males are programmed to procreate, females are the ones who stay at the nest to nurture and raise the resulting young. Instinctively, we know that letting our natural sexual impulses rule the day would mean that we would soon have new and awesome responsibilities. Having a partner to share them would be desirable. So we females are programmed to want a relationship along with our sex. Birth control or no, that’s our basic instinct.
