Immature high school boys?

all the guys in my highschool are so immature! It makes me think that the kind of guy im looking for doesn't even exist. I mean, yeah im no supermodel, but im not a brainless ditz like the chicks that have a new boyfriend every week. is it crazy that at 17 im actually looking for a serious mature relationship....wow hahaha maybe I am asking too much. my friends trip over themselves trying to get at guys who are really just cute jerks, guys who make a lot of ual jokes and are just disrespectful of girls or expect them to be aneroxic and submissive. It makes me nuts. The last guy i fell for seemed perfect....until I learned that he slept around even more than the preppy girls all put together.
