I agree with DrNortherner,re the visual thing. I think men are very simple creatures(not simple as in stupid) but they are not too complicated to work out.
They act on instinct, if a guy feels sexy and if they have a porno mag or look at images then so what? satisfying their urge.
I'm sure some people will understand me when I say you can't be bothered to have sex sometimes, too knackered, too late, need a shower, can't be bothered la,la la. Porn for a man may come in useful in this situation?
Some me do, some men dont.
Men looking at porn, can't see what the big deal is?
Fair play to them, it's one area in their life they dont have to compromise.
