Men, so the conventional wisdom goes, tend to desire more than women are willing to give them sexually. The granting of sex is the most powerful weapon women possess in their struggle with men. Yet in each new sexual negotiation a woman has with a man, she not only spends down that capital, she begins at a disadvantage, because the potential losses are always greater for her. A failed or even successful single encounter can be life-altering. Whatever “social construct” you might impose upon the whole matter, nature imposes much more rigorous consequences on women than on men.

Over the years, different strategies have been offered so that women could avoid the more subjugating consequences of sex. Though methods of reversing the biological power dynamics between sexes date back to ancient Sparta, the premise had always been confined to the fringes of society until the sexual revolution of the 1960s, a period in which many feminists considered marriage the primary mechanism for women’s sexual conscription. The liberation on offer was sexual freedom for women—and their partners—through open marriages and sex communes. It’s worth noting that these polyamorous arrangements usually had at the center a male patriarch who reaped the perks of women’s newfound freedom. This experiment was short-lived, as sexual jealousy seemed an impossible force to rationalize, and children conceived on the grounds of a canyon commune needed more stability than a group of wayward adults could provide.

But the reactionary political correctness of the 1990s put forth a proposition even more disastrous to women than free love: sexual equality. With the rise of PC culture, the notion of men and women as sexual equals has found a home in the mainstream. Two generations of women, my own included, soared into the game with the justifiable expectations of not only earning the same wage as a guy, but also inhabiting the sexual arena the way a man does.

Armed with a “Take Back the Night” pamphlet, we were led to believe that, as long as we avoided the hordes of date rapists, sex was an egalitarian endeavor. The key to sexual harmony, so the thinking went, was social conditioning. Men who sexually took advantage of women were considered the storm troopers of patriarchy, but women could teach men to adopt a different ideology, through explicit communication of boundaries —“you can touch there” or “please don’t do that.” Thus was the dark drama of sex replaced with a verbal contract. Once the drunken frat boys and brutes were weeded out, if we gravitated toward a kind of enlightened guy, an emotionally rewarding sex life was ours for the taking. Sex wasn’t a bestial pursuit, but something elevating.

This is an intellectual swindle that leads women to misjudge male sexuality, which they do at their own emotional and physical peril. Male desire is not a malleable entity that can be constructed through politics, language, or media. Sexuality is not neutral. A warring dynamic based on power and subjugation has always existed between men and women, and the egalitarian view of sex, with its utopian pretensions, offers little insight into the typical male psyche. Internet porn, on the other hand, shows us an unvarnished (albeit partial) view of male sexuality as an often dark force streaked with aggression. The Internet has created a perfect market of buyers and sellers (with the sellers increasingly proffering their goods gratis) that provides what people—overwhelmingly males (who make up two-thirds of all porn viewers)—want to see or do.

The heated act of sex often expunges judgment, pushing the participants into territory they hadn’t previously contemplated. The speed at which one transgresses, the urge to reach oblivion, the glamour of violence, the arbitrary and shifting distinction between acts repulsive and attractive—all these aspects that existed only in sex are now re-created through Internet porn. You could be poking around for some no-frills Web clips of amateur couples doing it missionary style, but easily and rapidly you slide into footage of two women simultaneously working their crotches on opposing ends of a double-sided dildo, and then all of a sudden you’re at a teenage-fisting Web site. All of this happens maybe by accident—those pop-ups can be misleading—or maybe, and more likely, it happens because in that moment it’s arousing, whether you like it or not. Consuming Internet porn, then, mimics many of the sensations found in sex. It’s overpowering and immediate; it is the brute force of male sexuality, unmasked and untethered. Martin Amis, in his fragmented fictional meditation on male depravity, Yellow Dog, depicts the delirious and uncontrollable effects of viewing porn. Amis writes:

He slithered around in his chair and made a noise intended to drown something out—my God: pornography turned the world upside down. You gave your head away, and what your mind liked no longer mattered; now the animal parts were in the driving seat—and tall in the saddle.

Hard-core porn, which is what Internet porn largely traffics in, is undoubtedly extreme. But how is sex, as a human experience, anything less than extreme? Not the kind of sex (or lack thereof) that occurs in marriages that double as domestic gulags. Or what 30-somethings do to each other in the second year of their “serious relationship.” But the sex that occurs in between relationships—or overlaps with relationships—where the buffers of intimacy or familiarity do not exist: the raw, unpracticed sort. If a woman thinks of the best sex she’s had in her life, she’s often thinking of this kind of sex, and while it may be the best sex in her life, it’s not the sex she wants to have throughout her life—or more accurately, it’s not the sex she’d have with the man with whom she’d like to spend her life. The manner in which one physically, and emotionally, contorts oneself for sex simply takes sex outside the realm of ordinary human experiences and places it in the extreme, often beyond our control. “Tamed as it may be, sexuality remains one of the demonic forces in human consciousness,” Susan Sontag wrote in Styles of Radical Will. Yes, it’s a natural, human function, and one from which both partners can derive enormous pleasure, but it is also one largely driven by brute male desire and therefore not at all free of violent, even cruel, urges.
