I think that you should work on getting to know him for a while, and work it out slowly. It's just my opinion, nothing concrete, but the relationships that last the longest are based on much more than physical attraction, butterflies, or liking someone's personality. But I'm not you, so really the best thing you can do for yourself is to be yourself. Also, it depends on what kind of guy you want. Do you want to have to guess what he's feeling/thinking all the time(?) or do you want someone who's up front and takes charge (?). There's really no right/wrong answer, just go with your instinct as long as it's not declaring your love for him in the middle of class!! ;)
