It's really well written in the sense of flowing well and constructing narratives, and as an exposition of the author's point of view it's pretty well constructed.
Unfortunately, the quality of ideas is a lot more uneven; while I can readily accept the idea that male sexuality is typically dominating and aggressive, the article is otherwise filled with the type of crap you'd write in school to make a banal thought about The Great Gatsby stretch out to ten pages.
Sometimes the article reveals more about the author than about the purported topic:
Hard-core porn...is undoubtedly extreme. But how is sex, as a human experience, anything less than extreme? ...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.

Never was this made plainer to me than during a one-night stand.... He couldn’t stay aroused. Over the course of the tryst, I trotted out every parlor trick and sexual persona I knew....in a moment of exasperation, he asked if we could have anal sex. I asked why.... He answered, almost without thought, “Because that’s the only thing that will make you uncomfortable.” This was, perhaps, the greatest moment of sexual honesty I’ve ever experienced—and without hesitation, I complied. This encounter proves an unpleasant fact that does not fit the feminist script on sexuality: pleasure and displeasure wrap around each other like two snakes.
And it gets even worse when she starts talking about male desires:
ONE OF THE most punishing realities women face when they reach sexual maturity is that their maturity is (at least to many men) unsexy. Indeed, we now have an entire genre of online smut politely called “Lolita Porn.”
...
Indeed, porn stars no longer look like porn stars. The image of Jenna Jameson, America’s most famous professional porn star (and a best-selling author)—with her comically huge breasts, overextended blond extensions, and artificially tanned skin—has been supplanted by the new face of pornography: a pale, naughty, 19-year-old with A-cups and a bad haircut, her face illuminated only by the bluish glow of her Mac.
If you actually look at the most viewed or top rated videos on a porn aggregator site, the actual evidence doesn't bear out her assumption here. Yes, there's a wider variety of porn available. There's a wider variety of everything available; it's remarkable enough to write about that, even though the subject has been thoroughly covered by now. But the minute you've hinged your article on the argument that men don't like big tits anymore, you've disengaged from reality entirely.
