I play a female character, even though I'm male. However, I do tell others on WoW that I am female. I don't consider it lying as such, it is an expression and veritable expression of my feminine side. I don't really identify with the gender binary for the most part, but I do lean towards female. I enjoy roleplaying as female, it is a sort of online cross-dressing.
I severely despise the "chainmail bikini" style armor. Indeed, I find the concept of having such revealing armor just for females somewhat offensive.
