You must not know about modern day science in those types of surgeries. They give the person a p**is. There’s a whole book talking about how a trans man became who he is today. I can send you the book if you like.
Ok, we can all agree that BIOLOGICALLY there are 2 genders; male and female, and then there’s what we identify as, such as male, female, non-binary, trans, pan gender and so on. I don’t understand what’s so hard to understand about this.
