Need advice, should I tell my friend I like him?

Long story short.. I have a good friend, I never thought he was gay. But I recently found some gay porn on his computer (it was by accident, but once I saw I looked more because I was completely caught by surprise, and found a good amount of gay furry porn and some regular gay porn. There was also straight porn and straight furry porn, but the fact that there was so many gay furry comics makes me think it must turn him on. ) I always thought he was 100% straight, but now this has me thinking he must be a little bisexual. I've had very strong feelings for him for a while now, and now that I think he might be into guys, it's driving me crazy and I feel like I need to make a move. It's weird because we're like best friends, we're even going to be living together soon as roommates. I think he's probably never thought of acting on any gay urges just because of the stigma, and probably going to remain "closeted", but if that's the case then I feel it's up to me to make a move, because I feel like I'll regret it if I dont. He'll definitely be surprised but maybe he'll be into it. It's probably mostly a bad idea because it could get a little awkward, but we're good enough friends that I don't think it would ruin our friendship, and I can't help myself I feel like I need to know. If he does reject me it won't be the end of the world, and at least I'll know and maybe if he atleast knows how I feel that might be the start of something. What do you guys think?
