Idk. Why would someone want to have a man's ass and voice? Seems weird to me. Yet about half of the world seem to want to be guys. And most of those are happy to be a choose to be a guy when customization is an option. I can't answer why so many guys consistently and choose to be guys in game (and sometimes have pride in their characters appearance and try to brag about their it) or some tease other people they perceived as guys for choosing to be a girl in-game when I can't understand why they want to be guys in the first place.

For me, I relate more to those who make fun of themselves for using that excuse because they were in denial. I've definitely been there. Of course there are guys (cis or trans) who like playing as girls too; I just can't relate (aro-ace spec).
