Is there something wrong with me?

I don't get it. I'm 16 and I still haven't had my first kiss, and everyone around me already has. Hell, most of my friends have already had sex. I don't get it. I'm always nice to girls, and they always tell me I'm a great listener and I'm nicer than anyone they've gone out with. So what does that even mean? I always get stuck in the friend zone somehow. I know I'm not ugly, and I have confidence in myself, after all I work out 4 days a week, and I am the strongest guy in school, but I never act conceited about it, but it is still known. Girls always tell me I'm cute or handsome, yet no one really likes me. I find myself thinking that almost every single girl at my school just isn't what I want in a girl, but are my expectations too high? I don't understand. Why is it that no matter how hard I try, the girl always casts me off and goes off with some other douche. I'm starting to think this is a curse, that I won't really have a decent girlfriend, ever. I was forced to break up with the first girl I really liked by her dad who was racist. I just need to know what I am doing wrong.... People tell me I'm really funny, and sweet, and nice, and cute but, why doesn't any girl like me? Or if they do how can I tell. Im just utterly confused.
