I'm not either.
I always do things alone. I study alone, I eat alone, I work alone.
But atleast one night a week go do something you like in a public place. See a concert/movie/play/whatever. Do SOMETHING. If you can't make friend's at events like this then you need some help. As long as people see that you are goal oriented, happy with who you are (even if that happens to be a loner), and confident with your mind and body they'll come to you. No need at all for you to mingle with people and be social all the time.
Same applies to women. I don't go clubbing and make approaches all the time like a lot of guys on these boards do. I just keep moving closer to where I want to be with my life through school/work very independently and almost anti-socially, and people naturally take notice whether or not I talk about it with them. You're bound to be approached by or have women introduced to you by mutual friends anyhow.
The point is: you don't have to be a guy with amazing social status to have an awesome ltr or even have casual sex on a regular basis. As a matter of fact I think LOTS of women are really REALLY turned on by guys that stick out of the crowd by being super independent.
