I'm a male and I prefer to play female characters as well. Usually they have superior customization options (my opinion) and while it does get old, I've been asked by a lot of players if I'm a girl or guy. I always answer it honestly because I'd rather not run the risk of being stalked or bothered by random players on a regular basis. In the end I agree with a lot of posters here, it doesn't really matter what gender you play as. There's a lot more pressing matters in game to worry about than trying to figure out the person behind the character.
