should I make a move?

Okay, so I am 16 and I have been talking to this guy in a class of mine for maybe 6 weeks or a month. So I'm crazy into him and I flirt with him and I've gotten pretty blunt with it. I told him he's pretty, and he has great eyes and I jokingly said he was like the perfect person, and he didn't seem weirded out about any of it. He's said a few cute things to me, but not that many; but he does talk to me for the entire hour every day. We have the same sense of humor and we both really enjoy the time we spend together on the daily. I know this sounds stupid, but I can actually feel sort of a spark (but it's probs just me). My question is, because I've never had a boyfriend and this guy is CRAZY out of my league, what I should do? After our scedules change in a week we probably won't see each other much. I like him sooo much but I don't want to ask him out because I don't think he has feelings for me, and I don't think I could face the rejection. But I don't want to miss this opportunity just in case he does have feeing for me. HELP
