I don't see anything wrong with it whatsoever. And I'm happily married. Obviously we're talking porn with consenting adults; no kiddie porn or any other sick behavior. They used to say that teenage boys checking out magazines or watching porn, would set them up to be disappointed with "real world" women. But I don't necessarily agree with that theory either. My wife is better looking than any porn chicks I've seen, and most of us on this forum are in better shape than the guys in the usual porn, so no inferiority complex either.
