choices, choices, choices

Okay... so I have the guy in my grade (11th) that is really shy and he has a crush on me. I also have this guy that is in the grade above me, and we had sex.  Then, I have this guy that's a freshman in college that I'm just starting to talk to.  I don't know what I'm doing right now.  I'm just scoping my options because I am single (just got out of a 7 month relationship a month ago).  Talking isn't dating, so I'm not cheating.. right?
