Why don't I get asked out?

Guys always stare at me even for creepy amounts of times when I know they're looking. Like last week this guy was staring at me the whole cl basically and I looked at him to see if he would look away but he didn't and it creeped me out. Then like when we were doing group work guys will like talk to me and look at me and sometimes rudely not acknowledge other people. And there's one guy who always watches me in the hallway and then one who will watch me then look at down then watch me again. But none of the them actually talk to me they just watch me/stare or look at me. There are lots of other guys too and it seems like they like me but then I guess they don't because they don't do anything. I'm not like slutty or I wear like dresses and skirts with black tights or legging, skinny jeans and heals. But in a refined short of way.I'm nice, and really involved in school. I am in almost every club, and I do some sports. I'm running for president next year, I'm on like the selective leadership comity and things like that and honor roll. But I don't flaunt any of it and I try to be really nice and helpful to everyone but not to the point where they walk over me. I am very opinionated and share what I think in cl. Why don't guys like me?
