You’ve really asked me two questions: Why does he do it and why do you suddenly find that it bothers you? I think he does it because after all these years of looking at such material, he’s hooked. Just the way I tell women not to overdo it using a vibrator because they can get hooked on the strong sensations, men can get hooked on the images they see in porn. Where a couple of hundred years ago a man could become aroused by the sight of a woman’s ankle, these days, after seeing so much x-rated material, your ankles and every other part of you are not enough for him. And I think at least subconsciously you realize that and that’s why it bothers you.

 I’m all for masturbation, but it can be abused and I think your boyfriend is at that stage. He requires what he sees in these films to become aroused. And I must tell you, he’s probably watching the latest reel he’s seen in his head when he’s having sex with you. I think you have to talk about this and see if he’d be willing to cut down on this activity. At the very least, if he tries and fails, he’ll see for himself that he does have a problem and maybe go for professional help. If he keeps this up, he’s going to lose you and not be able to stay with any woman, and I’m sure he doesn’t want that. He may act very defensively when you first bring it up so if you want to stay together, tread lightly at first, but also be firm. Getting him to cut down is something you’re doing for yourself, but also for your relationship and for his well being as well.
