Why Cant I Get a Boyfriend?

Okay so I'm not going to say that I've never had a bf before. Its just that all the guys I have dated were long distance relationships. I don't really have that many guy friends because I'm shy. What would be some possible reasons why no guy from my school seems to like me. Oh and I'm not ugly or fat. I would say I'm okay looking and have an average body. Btw there's some girls who are uglier than me seem to always have bfs.
