I'm a pretty big geek, and women are turned off by that.
Eh, it doesn't matter. I will probably turn 21 and still be a virgin. It's funny, whenever I was going away to college my dad wanted to buy me condoms, and I told him no, because I knew I wasn't going to need them. People asked me how I had so much money for video games, because I think and they think I'm pretty decent looking, and whenever I told them I've never dated anyone for more than three months, it makes sense to them.
Eh, not a big deal though. I've got other shit to worry about besides women.
