From what I’ve read, being transgender isn’t about clothes and stuff at all, or not mainly anyway. It seems that people are born with a ‘body map’ in their brains that sometimes doesn’t correspond with their actual body, so that they feel there are parts missing that should be there, and other parts that feel like they’ve been sewn on by Dr. Frankenstein.
I’ve read that too. Is there evidence?
No, alas, I don’t know of any official studies or anything, I’ve just read stories by transsexual people saying that’s how they feel.
