Personally, I feel like telling a boyfriend that he can’t look at porn is a pretty huge boundary-buster. No one has a right to tell anyone else what they can and can’t do during their, errrr, “private time” (assuming whatever they’re looking at isn’t illegal, obviously). I have to agree with Moxie here, if you don’t cut it out, he’s running to the ex. My grandmother has a saying, “Whatever you fear most, if you let it run your life, will take on a life of its own and wind up actually happening.” Everyone gets insecure, but you’re really taking it over the top and it has nothing to do with what your boyfriend’s sex life was like before you came into the picture, his exes or anonymous boobs on the internet. Get to the root of why you’re feeling this way and I promise you’ll be about a million times happier for it!
