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)
