As far as your looks go, as others have said it's impossible to tell without seeing a picture.
Your personality seems good though, tell me do you talk to guys or is the vast majority of your company female? Are you shy or hesitant to try new things? Are you open minded? Do you have overprotective sibilings/parents?
Hahaha I used to have the same problem. I talked to a lot of guys about it and you'd be supprised by how many guys are intimitated by beautiful girl. When you go out you'd be supprised by how many guys would sit and stare at you but won't come over and say anything
