I too play a Female Avatar as an Objective Male, however I ensure my Female Avatar is as Androgynous as possible. Like no obvious male build or female build. Just an androgynous thing. I do not want to play Le Funny Creatures or Le Random Meme characters. I prefer to present myself in VR Chat as my authentic self, an asexual, silly androgynous being.

Because this is my line of thought, I believe everyone else also uses Avatars that represent their authentic self. So if you are an Objective Male but play a cute girl, your authentic self is a cute girl. If you play a sexy girl, your authentic self is a vain slut. That's okay, I respect that.
