I'm also is several minds about this question.
Part of me wants to shout it from the roof tops. It isn't the ephany, it's the cartharsis. I hate being seen as I do, I hate even more having to play the part.
That leads to the second thought, how much of the pretense has been mine? I haven't fooled myself, but I have spent much of my life playing along with the preceptions and social expectations of others. I know what I am but have allowed what amounts to the threats of society, threats to castigate, to isolate, to attack, to ostracise, to influence how I managed my own life. I've played a part, written for someone else. But more, I've betrayed myself, who I am, what I am and in doing so, I've betrayed others in my situation. All those people out there, like me, pushed by social expectations and threat, to look and act like something else. I've let them down as much as myself.
Part of me wants to just live according to who I am, rather than what I fear. I don't need to wander around telling everyone I'm actually female, but look male, as if I am coming out of some hypothetical closet, seeking permission or confrontation. I am what I am.
In a way, I have thought about this in the past. I have thought about ticking the F box on forms. But in all honesty, the consequence of that will almost certainly be that I'd be told I was causing trouble, or even fraud.
I just don't see myself as some sort of TG version of Rosa Parks, taking on the entire legal structure, not to mention, the social norms of my society. I want to live without shame and the fear of shame. But I'm just not the one to take on the world.
