My Gay Roommate Fucked Me Last Night While I Was High On Ecstasy.

Ryan has been my roommate just for this school year because we are both out of state transfers. I knew he had a crush on me or at least wanted the novelty of fucking a straight guy. Last night at a Halloween party I took ecstasy like I had a few times before. It does make me horny but this time was ten fold. I was craving human touch. I then hooked up when a fat girl but she kicked me out at 3am.
I got back to my dorm and acted like I was drunk, knocking stuff over and being loud. When I was sure Ryan was watching me I pretended to pass out on top of my covers naked. He climbed into bed with me and started immediately feeling me up, it felt amazing on Ecstasy. I could not stop moaning. He then got naked and started Luding me up. He took it slow penetrating my ass but even the pain felt amazing. He got off, then sucked me off. He told me he never had a partner orgasm that hard.
Woke up around an hour ago with him spooning me. I left and acted like I didn't remember most of it. Not sure what I should do. I definitely don't find men attractive. I also can't believe I hooked up with a fat girl. I am dreading going back to my dorm room and facing Ryan. WHAT SHOULD I DO?
