As I am not transexual, I can't speak from experience, but I can speak from observation. My observation is that when people transition, it is from a place of standing at edge of the abyss. It isn't "I think I'll transition.". It is "I MUST transition.". Granted, people may delay transitioning due to medical, economic or family reasons, but that doesn't change the MUST.
In that context and given all of the checks and balances in place, how could anyone transition if they didn't have to?
