Guys help! My boyfriend is obsessed with porn.

We've only had a computer here at home for 9 months or so, and since then, especially over the last 6 months my boyfriend is constantly checking out online porn.

I don't care that he does this sometimes, but he does it ALL the time. I'll run to the store and he instantly gets on porn and when I'm at work he's online checking out porn for hours. He's lately, because I'm on vacation over the holidays, going on porn sites after I go to sleep.

My problem is, I hardly get sex now maybe once a week, when I use to get it more. The other night we had great sex and I know he was satisfied, yet when I fell asleep he went online checking out porn. I feel like I have to compete with these porn sites and it's driving me crazy.

Can anyone tell me why he does this? He seemed to be satisfied with out sex life until we got the computer and 24/7 access to porn.
