Why are people crushing on me?

Ok so I'm pretty but nothing special ya know kinda average bland looks: really dark brown hair, lightly tanned, between skinny and curvy, dark green eyes, tall. As I said before nothing special I used to have a lot of guy friends but no boyfriends because no one seemed interested but I went to my friends party about a week ago and there was this one really cute guy totally crushing on me and he wasn't exactly shy about it either lol anyway we are complete opposites I'm more of a rocker screamo girl and he's more football, player kind of guy ya know? Anywhooo the same happened with this other guy at a concert, then another guy who btw is my best friends cousin and loads more.... I just don't get it! Im bubbly, a tad crazy and apparently I'm cute when I get angry so I mean I have no idea what's going on, I have never had much male attention until now. Why now? I'm not even interested in a boyfriend I just want to get through high school fast and painlessly. Oh and also loads of older guys are being pervs how can I stop that? I don't dress slutty I just wear tight black skinny jeans, a band tee or maybe a spongbob tee and a hoody all ways with converses or vans and my awesome bow next to huge hair haha lol Anyway am I flirting to much by accident? I don't know but please help. Thank you :)
