You know, this reminds me of when I attempted to use spells to change my gender when I was 20. I am by no means a witch but I was desperate for a change. There was this spell I used were you had to do something at night when the moon was the brightest or something (I forgot) and I think it required some other things, but nothing came of it....at least I think so lol.
Anyways, a year later I started HRT (I was 21) and so yeah. This is a really old post so if anyone else is reading this, then the best way to change your gender is to go out there and just do it you know? It is not easy, but it is the only way unfortunately.
