How to get guys to look at you as more then a friend?

I'm going to be a sophomore this coming year, and all ive done is kiss. my school isn't all that big, so stuff gets around pretty fast. most of the guys think I'm prude, and I wanna change that. how do I get guys to look at me differently? a little change in appearance? acting a little different? I'm not looking to turn into a slut, I just want to be noticed more. oh and I guess I'm considered "hot"
