No, you're not wrong. Girl, you sound like any man's dream woman. Most men LOVE it when their women try to have sex with them- it makes them feel wanted and boosts their ego. And it's shocking to me that you walk out in stockings and a garterbelt yet he still doesn't seem interested??? Something is *seriously* wrong. Wouldn't that be something men see in porn? So then, why would he rather see such things in porn rather than in real life?
I think HazeyAmber is right, he definitely has intimacy problems. It's like the porn is a way to avoid real human-to-human intimacy with a partner. He's obviously scared of getting too close. It also seems that he's got a porn addiction problem. I wouldn't/couldn't tolerate that.
It's definitely a serious thing when porn is getting in the way of the relationship, both intimately-wise and sexually-wise.
