I just want to hook up. Is that so hard?

OK I hooked up with this guy over the summer, we are friends and all I really want is a hookup, I'm not looking for a boyfriend just a guy to fool around with. But I think that he might not be interested. I'm thinking about just making the first move, but am worried that if I do and he doesn't respond that I will make a fool of myself. So my question is, is should I go for it and just make the move? or should I be sure first that he's interested. thanks
