I consider myself to be average looking, or maybe that's just my perception, since I don't get hit on much in public or school, except when a guy is asking me for directions on the train, but it seems like guys in school are a bit hesitant to talk to me, as in they go out of their way to sit next to me, and they look at me... I don't think I'm anything special, but why won't guys in college approach me easily like they do to the other average looking girls? My male professor has been the only" guy" so to speak who asked me where I come from and joke with me. Guys just sit near me in class and that's it... If a guy sits near you does that mean he's usually interested or just his preference (assuming I tend to sit in the same seat every class)...
Average looking depends on who you ask. I've had girls that I thought were drop-dead gorgeous, while my friends, looking at the exact same woman, couldn't find the attraction with a map and a Sherpa guide. Inversely, I've seen my friends drool over girls while my only thought about her was "meh".
Like others have said, if there's a guy you like who happens to sit near you, say hi! Give him some kind of opening to talk to you. Who knows where it could lead?
Personally I have never dated any girls in class when I was in college and I was very shy around them at that now. Nowadays I wouldn't have they much of a problem to start a conversation but I am understand how some people (especially guys) can be shy about talking. There's nothing wrong in you talking to them first. Once they get to know you then I am sure you will have a few offers from guys.
You've gotta be friendly and approachable too. You can't just want guys to approach you just because you're pretty. And what's wrong with going out of YOUR way to talk to guys? Why do guys have to be the ones to go out of their way to talk to girls? No offense, but in this situation you're the only one to blame for not talking to many guys :/
I don't bother chatting up any girl that doesn't even bother to look my way. A glance and a smile will do, but if I don't even get that, then I figure she's not interested in talking. So far, stepping out of that zone has proven me right every time.
I feel that I have the same thing, but asking guyfriends has helped me understand that my body language tends to be a the reason because of my attitude towiards guys that I know are just looking to be smooth. Maybe you should try making conversatoin because some guys are pressured, so you making the first move may relieve the stress for the boy and it'll make a steady progress.
Don't feel bad for boys that are intimidated because the good guys will eventually make move and not be scared. Patience is the key ;)
