We've been dating for over 3 years now. At first it was like every new relationship, we couldn't keep our hands off each other. Now we maybe have sex every couple of months. Recently I've found porn on our computer and left on the tv. I know he watches and I'm ok with it but I feel like its starting to effect our sex life. He gets defensive and upset when I try to bring up the subject. I've tried telling him that it doesn't bother me and I even find it a little exciting but he always denies it and just plays it off. The only thing that bothers me I guess is that he won't fess up. I know it's silly but I don't know the best way to even try talking to him about it. And I don't understand why he won't even own up to it. And I don't want to keep feeling like it's interupting our 'time' together.
