I'm turning 20 in 9 days and have never been in a relationship ov any kind. I'm always the "nice guy friend" and nohing more. I don't think I'm unattractive and I'm definitely not rude or anything. I just dont get it.

Hey, man, don't give up. Even though you are getting older you are still pretty young and have lots of time for love to find you. I was never really in a relationship until I met my future wife when I was 27. The main thing is to be happy in the state you are in. If you come across as confindent (not cocky) and happy then women will be attracted to that. Just enjoy whatever life throws at you and it will all fall into place. Don't get depressed, give up or act desparate (desparation will repel the women for sure...they can smell it! haha).
