You're missing the point. Men get off to tons of things that aren't for their "purpose". Style magazine, apple pies, armpits, furries. The point is that reality is huge for porn. Men hear there is a site with pictures of "REAL" women looking for sex(cheating or not) and they are going to go look at those women and get off, especially if they can see nudes or sexy images. Does it make them pervs or weird or whatever, maybe, but it doesn't make them cheaters. And before you say out them anyway for being gross or etc, well then you are no different than the judgy hypocrites that make the news.
