If we hooked up and are still friends, do you think he is ever going to want to hook up again?

Here's the background info: I used to hook up with his roommate (no, it's not as bad as it sounds.. I hope) who later ditched me. I decided it wasn't worth making it a drama, so I just let it p and moved on. I'd always kind of found this guy (not the roommate) very attractive but could never really tell if he thought the same about me because he's a generally flirtatious guy. Nevertheless, he was still my friend and we always got along. About a month and a half later I was at a track party and me and this guy ended up leaving and hooking up back at my place. I didn't want to get ahead of myself, so I just waited to see how he would follow up. He never asked me to hang out or anything, but he still acts really nice and friendly to me... I'm very happy that things never got awkward between us. But I still find him attractive and would have no objections to hooking up again... and again... is there any chance we'll do it again?!
