Is it normal that even though I am a straight male, I am terribly attracted to my roommate. I have even tried to grope him when I was slightly tipsy and he was passed out drunk. He is the only guy I have ever been attracted to, and it sometimes makes me wonder about my sexuality. What is going on with me?

Nah, there's nothing wrong with it. Don't sweat it. I've heard lots of stories of straight people being attracted to the same sex. And, hey, maybe he's just too hot for even a straight guy to resist, and if so, check and see if he's bi. Everyone experiments in college ;)
