I've pondered the possibility of transitioning many times throughout my life. I've come to a place where I've realized that I don't entirely identify as either female or male. Would I still be considered trans? How do I refer to myself in regards to gender? What if I want just top surgery?
Those are answers that should be between you, your trans-positive therapist and your doctor. The internet is not the place to find those answers.
When one does any type of transition, it's a bit like taking your home and turning it upside-down and shaking it. YOU will have to go through it all and decide what's BS and needs to go and what's authentic and needs to stay.
