OMG I have the same exact theory and my therapist has confirmed the exact theory. Wow chills here. I KNOW this has to be it. It makes total sense. How can kids at a young age have a desire to be more female and try female things. It is programmed at that point. The chemistry in the brain HAS to change forever. I feel this absolutely is true. There is no escaping these feelings for us. You can't throw it away, you can't quell it forever, you can't pray it out, you can't drug it out. It will come back because it is just in your brain. To what degree is the question I think and that determines how far you feel you need to go to feel right.
