Should I be concerned?

My boyfriend of a year is highly active with . I think is disgusting, degrading, and a total waste of time when you have the real thing right in front of you. When I'm not around he watches and downloads it a lot. I have even recently found out that he's a moderator for a forum. To me this would say that he's a very ual person, but we only have about once every week and a half. Not by my choice...if it were up to me we would make love every day. This really bothers me and I've tried talking to him SEVERAL times but it's like he doesn't acknowledge the way I feel and I can't get him to stop with the thing. He says it's just a hobby but I think it's more than that. I feel like I should be enough and instead I feel alone. Did I mention that we live together also, so there's nothing that keeps us "apart." We are both in our 20's so both of our drives should be constant in my opinion. Am I over reacting by feeling like he should cool it with the and realize that he has something much better than that in his life?
