Nerd alert!?Nerd alert!?

There's this nerdy guy at my school and we are really good friends because we have always been locker neighbors every year and I kinda like him but he's one of those guys who no one dates. If I did People would judge me and I would become a loser. I don't want to have a secret relationship with him because that gives off the message that I'm embarrassed to be with him. Any advice?
