I have a thing for assassins. I \, and I know this is a bit messed up, But I ABSOLUTELY ADORE them. *fangirl squeal* Sorry, I'm talkative.
Anyways, it depends on you. I'm not picky. And no I'm not someone who forces the awkward torture of going through anything over PG-13, so other than that, it's realtively easy to play a guy. If you want to be the female though, you can. I have no preference.
