Porn

That should get your attention.

Americans look at lots of porn. We pay a buttload of money every year on porn. Men look at it, women look at it, and it destroys families and marriages.

I listen to a podcast by a reformed guy named Mark Driscoll. I disagree with some of his theology, but he's a great speaker and teacher. He has an e-book out called "Porn Again Christian," and it is available at http://relit.org/porn_again_christian/. He recommends it for all men, but I don't think it's inappropriate for mature adults of either gender. It's a great resource.
