I like humanoidal races which looks good(or have good racials).
About that "male players playing with female chars". I personally don't give a fuck what race/class you play as long as you do it good and it had no impact on guilds/my goals.
But I think there's a thin line between "playing" and "acting".
If you are playing as a female and acting normaly then it's fine, but if you are acting like a female, then seek help.
And the "I want to look on the female's ass rather than male" - if you're looking at your character's ass then you're just playing wrong game.
