I've known of at least one or two females who play males because it "fits with the story more." I forget the name of the individual's character, but she played a male druid (because the notion of female druids seemed silly according to lore--talk about taking things a bit too seriously). Her husband, IIRC, played a male gnome. That was rather funny to watch. Although, I admit it'd be even more amusing if it were a female gnome.
As an aside, most people who have confused me with Turus usually learn otherwise rather quickly. I'm very moody, and I'm also pickier about my typing. And, well, the trolling nature of my personality tends to give me away no matter how hard I try otherwise.
