“We have good news and bad news. The good news is that the dismal vision of human sexuality reflected in the standard narrative is mistaken. Men have not evolved to be deceitful cads, nor have millions of years shaped women into lying, two-timing gold-diggers. But the bad news is that the amoral agencies of evolution have created in us a species with a secret it just can’t keep. Homo sapiens evolved to be shamelessly, undeniably, inescapably sexual. Lusty libertines. Rakes, rogues, and roués. Tomcats and sex kittens. Horndogs. Bitches in heat.1 True, some of us manage to rise above this aspect of our nature (or to sink below it). But these preconscious impulses remain our biological baseline, our reference point, the zero in our own personal number system. Our evolved tendencies are considered “normal” by the body each of us occupies. Willpower fortified with plenty of guilt, fear, shame, and mutilation of body and soul may provide some control over these urges and impulses. Sometimes. Occasionally. Once in a blue moon. But even when controlled, they refuse to be ignored. As German philosopher Arthur Schopenhauer pointed out, Mensch kann tun was er will; er kann aber nicht wollen was er will. (One can choose what to do, but not what to want.) Acknowledged or not, these evolved yearnings persist and clamor for our attention. And there are costs involved in denying one’s evolved sexual nature, costs paid by individuals, couples, families, and societies every day and every night. They are paid in what E. O. Wilson called “the less tangible currency of human happiness that must be spent to circumvent our natural predispositions.”2 Whether or not our society’s investment in sexual repression is a net gain or loss is a question for another time. For now, we’ll just suggest that trying to rise above nature is always a risky, exhausting endeavor, often resulting in spectacular collapse. Any attempt to understand who we are, how we got to be this way, and what to do about it must begin by facing up to our evolved human sexual predispositions. Why do so many forces resist our sustained fulfillment? Why is conventional marriage so much damned work? How has the incessant, grinding campaign of socio-scientific insistence upon the naturalness of sexual monogamy combined with a couple thousand years of fire and brimstone failed to rid even the priests, preachers, politicians, and professors of their prohibited desires? To see ourselves as we are, we must begin by acknowledging that of all Earth’s creatures, none is as urgently, creatively, and constantly sexual as Homo sapiens.”
