Do what you want man, or women, or what ever the fuck you are, just don't force others along with you.
MGTOW though is about being free of a need or want of dating women. MGTOW does not care how much or how little pussy he gets, he is above such things. If a women wants sex from him he may take it or leave it, but on his terms, and he has no problems saying "There's the door, bitch" if she gets needy.
As a MGTOW dressing up and pretending to be a women to get pussy seems like way WAY too much work, and frankly sounds like a really embarrassing and utterly pathetic thing to do.
