Hehehe, you said hit box. Sorry I couldn't help myself. Anyway, I am a guy, 31 years old, married, 2 kids. I almost always play as a female toon in games if I have the choice. Certainly my main toon is female, sometimes alts are male. The original reason was simple: if I'm going to stare at a characters ass for 100+ hours then it might as well be a girl's ass. I know it's very juvenile, but I was a lot younger when I started playing MMOs. Now it's just more habit than anything. It's just a game, who cares what race/class/gender our toons are? The vast majority of the people I play with are guys, and I would say that consistently, across different games, about half play as female toons and half as male toons. I really don't think there's any underlying psychological issues or reasoning for why people play as different genders in games. As was stated, if this was a dating site and you were pretending to be a different gender, then maybe there would be something to explore. But this is just a game. No impact on real life. Just a game.
