Hooking up

I'm no stranger to casual sex, and I very much enjoy it. But I'm looking for some advice here. A guy I've had a bit of a crush on for 2 years has recently started snapchatting and texting me. I know he wants to hookup (and I do too! I've had my eyes on him for years) but I'm a little scared to. I'm afraid I'll catch feelings for him if we have sex, and I'm wondering if anyone else has been in this kind of situation. Should I hook up with him, and risk catching feels or cut it off now?
