Will you stop that meow crap? If this is your idea of role-playing, you are doing a poor job. See, the impression you are giving is that you are a teenage boy trying to role-play a sexy woman (or, your idea of one, anyway), for reasons that should embarrass you. In case you didn't pick up on it, and your reply indicates that you didn't, Cat basically called you a cross-dresser (in real life).
You don't want to give people that impression, do you?
I think it's great to role play the other gender, provided you actually try to think and act like a member of the opposite gender, instead of a figure out of a wank fantasy. It's insulting to women and as noted above, embarrassing to yourself as well.
