Many trans people know that they are trans from the moment they are conscious of self
Like OldCrone I wonder about how someone knows they should be the other sex.
I mean, I can understand body dysmorphia or dysphoria. It's a pretty familiar feeling for many [most?] girls & women.
But what I don't understand, and what I would also argue is illogical, is that, feeling that your sex is wrong, that you automatically assume you must be the other sex. How would you know?
How can you be sure that the assumption that, if you feel dissociated from your male body, you must be a woman?
And, I mean, how binary is that?
