It is hard to ignore how many highly visible men in recent years (indeed, months) have behaved in sexually self-destructive ways. Some powerful men have long been sexually voracious; unlike today, though, they were far more discreet and generally used much better judgment in order to cover their tracks.
Of course, the heightened technological ability nowadays to expose private behavior is part of the reason for this change. But that is precisely the point: so many of the men caught up in sex-tinged scandals of late have exposed themselves - sometimes literally - through their own willing embrace of text messages, Twitter, and other indiscreet media.
What is driving this weirdly disinhibited decision-making? Could the widespread availability and consumption of pornography in recent years actually be rewiring the male brain, affecting men's judgment about sex and causing them to have more difficulty controlling their impulses?
There is an increasing body of scientific evidence to support this idea. Six years ago, I wrote an essay called "The Porn Myth," which pointed out that therapists and sexual counselors were anecdotally connecting the rise in pornography consumption among young men with an increase in impotence and premature ejaculation among the same population. These were healthy young men who had no organic or psychological pathology that would disrupt normal sexual function.
The hypothesis among the experts was that pornography was progressively desensitising these men sexually. Indeed, hardcore pornography's effectiveness in achieving rapid desensitisation in subjects has led to its frequent use in training doctors and military teams to deal with very shocking or sensitive situations.
