PLease answer...What's wrong with me.Why don't guys i like ever find me attractive?

You just havent found the right guy yet. Most guys have a pretty specific type of girl they like (so i'm told) or at least that they go after. You just gotta find a guy whose type you are. Before catching feelings for him ask casually what type of girl he likes (which will also tip him off that youre somewhat interested in him) and see where it goes from there. Good luck =)
