Most female toons are guys anyway. It's all about which backside you'd rather stare at
Ain't that the truth! Why else are the Tomb Raider games so popular - I doubt only "girls" play them.
Personally, I don't create alter-egos for myself when playing a game, I don't hard-core RP but still play each toon as an actual "individual" who I follow along/guide through the game. Therefore, I always have a mix of male and female toons in games because that's "who they are" so to speak.
