It’s an older article (2003), but Naomi Wolf’s piece (“The Porn Myth”) on how pornography actually deadens men against the real thing is worth the read. A few worthwhile quotes:

The whole world, post-Internet, did become pornographized. Young men and women are indeed being taught what sex is, how it looks, what its etiquette and expectations are, by pornographic training—and this is having a huge effect on how they interact.
But the effect is not making men into raving beasts. On the contrary: The onslaught of porn is responsible for deadening male libido in relation to real women, and leading men to see fewer and fewer women as “porn-worthy.” Far from having to fend off porn-crazed young men, young women are worrying that as mere flesh and blood, they can scarcely get, let alone hold, their attention.

Further:

But does all this sexual imagery in the air mean that sex has been liberated—or is it the case that the relationship between the multi-billion-dollar porn industry, compulsiveness, and sexual appetite has become like the relationship between agribusiness, processed foods, supersize portions, and obesity? If your appetite is stimulated and fed by poor-quality material, it takes more junk to fill you up. People are not closer because of porn but further apart; people are not more turned on in their daily lives but less so.

And again:

The reason to turn off the porn might become, to thoughtful people, not a moral one but, in a way, a physical- and emotional-health one; you might want to rethink your constant access to porn in the same way that, if you want to be an athlete, you rethink your smoking. The evidence is in: Greater supply of the stimulant equals diminished capacity.

After all, pornography works in the most basic of ways on the brain: It is Pavlovian. An orgasm is one of the biggest reinforcers imaginable. If you associate orgasm with your wife, a kiss, a scent, a body, that is what, over time, will turn you on; if you open your focus to an endless stream of ever-more-transgressive images of cybersex slaves, that is what it will take to turn you on. The ubiquity of sexual images does not free eros but dilutes it.

Interesting how, yet again, the old wisdom turns out to be correct—and because it actually leads to happier, more fulfilled, and (yes) sexier lives. This should be entirely unsurprising, but in the midst of a culture becoming increasingly sexualized and (at least for those of us regularly on the Internet) exposed to pornographic imagery, it’s worth the reminder.
