"I wish... That while there were two sexes, male and female, that Gender was chosen by the parents at birth, boy or girl, and the infant would be given a strong shot of estrogen or testosterone depending... and would then be raised as the gender that had been picked for them. I wish that in this reality, being straight was being attracted to someone of the opposite Sex, regardless of what Gender the person was, and that no matter how much estrogen or testosterone in the persons body, A Male would still get erections and could get a Female Pregnant, even if they were a Girl and Boy, respectively.
Jon only had a moment to reflect on his Wish, he wondered in this new reality, what Males would become girls, and which Females would become Boys, when he realized he hadn't excluded himself, there was a 50/50 chance he'd become a girl.
