One very real thing Porn does is raise sexual expectation artificially. In a nutshell, there is NO WAY any single human can meet every standard proffered by porn. For example a woman may be perfectly happy having sex with her husband, who is hung with 8 inches. He may be the biggest man she's been with, and she "likes it" more than the smaller-peckered guys she'd been with before.

So, she starts watching porn. and see's that it gets WAY bigger than that. At first, well, she just says "dang! that would be cool!" But as she watches more . . .well, she begins to want it more. And then . . . she realizes how easy it is to get "Big" in these modern times . . . do I need to continue?

I know people who had perfectly satisfactory love lives until one of them gets into porn. Often, it's allegedly to "enhance" their own monogamous relationship. And it can. But it often goes further, and I'm not talking about some obscure exception to the rule.

And it isn't just heterosexual relationships. It happens all the time in gay reationships too. (In particular, actually, but that's another debate)

The cold reality is that porn does raise sexual expectations to levels no one person could ever hope to meet. And humans tend to want what they watch and see as enjoyable, that is an inarguable reality. Whether it is some guy watching skydiving videos or footage of 4 chicks on a guy, it does increase their desire to experience it themselves. And human nature is a selfish nature, and that is also irrefutable.

Again, Porn IS harmful, and any assertion otherwise is laughably stupid.
