It's a tad weird actually. I am a straight guy who, surprise surprise, identifies as a male. Yet when I play something, not just the games here but any game which allows character customization, I choose to play as a woman. I guess it is two parts wanting something pleasant to look at and one part curiosity. There is also this small part which enjoys turning the character I play as into a slut (obviously applicable to the games here). Now, the weird part is, I have no desire to do any of that IRL. I am not promiscuous, an exhibitionist or want to get in relationships with ugly women. So it is an alter ego sort of thing, a guilty pleasure I can indulge in whenever I feel like but never let it escape the virtual world.
And I am fine with this.
