Can someone please change the description?
this is not a TS-story, as the guy is magically transformed into a pubescent/prepubescent girl.
This is a logic flaw as TS means that you apply phenotypical alteration via surgery, which leaves the character still having the original sex but the appearance of the other sex.
So, if he became a girl, this can't be TS and vice versa (i.e. he can't become a girl if this was a TS-story).
