I'm a happily married father to a 3 year old daughter and I use a female avatar. I do so for two main reasons:
1. I spend several hours a day on this game, a majority of that time is spent staring at the back end of my avatar; I prefer looking at the back end of a female to a male.
2. My wife is female, she NEVER makes a mistake and is NEVER wrong, I thought, WOW, that would be useful in WGT I want some of that, so....
