It happens to many of us from a very young age and it’s mostly where psychologists focus their diagnoses of gender incongruence nowadays. Less about what makes you feel like shit about your body and what make you feels amazing about expressing your mental gender. We don’t “identify” as another gender, our brains are physically another gender. Hrt allows our brains to function correctly. At least this is according to the current science. It’s science so new things are discovered but the research into transgender people’s brains has been stifled by church groups and bigots. I’ve been like this all my life and have euphoria with realising what it meant in my earliest memories.
