Is pornography driving men crazy?

It is hard to ignore that many highly visible men in recent years (indeed, months) have behaved in sexually self-destructive ways. Some powerful men have long been sexually voracious in the past. But unlike today, 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 uninhibited decision-making? Could the widespread availability and consumption of pornography in recent years be rewiring the male brain, affecting men's judgment about sex and causing them to have more difficulty controlling their impulses?
