My boyfriend watches bizarre porn! Help?!?!?

Sex Problems for Women

I have noticed over the last 6 months or so my boyfriend has begun to watch porn that I myself find absolutly repulsing. I can't even stand the thought of him or anyone for that matter wanting to watch some girl have sex with dogs or horses or any animal! That to me is disgusting, and inhumane. At first it was a once in a blue moon thing, but now it's more like a daily basis thing. He downloads movies of it all the time. I've never actually walked in on him watching them (THANK GOD!). He tries to hide it from me so that makes me think he's ashamed of watching it. Why would you hide something if you weren't?! This porn obsession of his has started causing problems in the bedroom. I don't know what to do. It's just a major turn off and I'm constantly thinking about it and if thats what he imagines when we are doing the deed. Can somebody help?! I don't know what to do!!!!!!
