That would make it an entirely different game. So there will never be a male protag.
Somewhat related question though, will there be any differences in writing in how both MC origins (whether they were originally boy or the girl) handle expectations of their current sexuality? I mean, they start to fantasize pretty quickly and never appear to be conflicted about the idea of other dudes putting their cocks in him/her or serving them sexually, i.e. ideas they likely weren't too keen on, or even considering, previously as a boy. Compared to being originally a girl.
(well, unless they're bisexual to begin with, i suppose)
