A lot of good things have been said here. Transition is a huge, terrifying thing.
I have found myself questioning the very nature of reality to explain this to myself.
I have gone through hell and back in order to figure out who I am and how "authentic" I am being.
Authenticity is a problem burdening all of humanity. We have a tendency to identify ourselves with labels, and not explore our own souls and learn about ourselves, good and bad. Most find something they don't like and run and find something to hide behind. Our economy is based upon that.
We are not those labels. Things like "male" and "female" are deeply misunderstood concepts. Truly gender is but another dimension of the universe. Terms like "male" and "female" only represent relative positioning in that higher dimensional space. Everything has a position in the dimension of gender, many languages recognize this in some way or another with masculine and feminine words.
And "sexual orientation"? lol. really now. love is love as long as two souls respect each other and nurture each other. everything else is made up nonsense based in fear and hatred.
Our bodies? vehicles, a really tight fitting outfit for our spirits, more of a fancy space suit. To think that someone is actually an abstract description of a sub-system code, poorly represented by an "X" and a "Y"? Really. dna is a fluid thing. It's always mutating. especially the 23rd chromosome. That "vehicle" blueprint is constantly being refined by nature. The dna is only bits floating on the surface of the pond, it is our spirits that make ripples in that pond.
But also sometimes you drive around in a car for years that you don't really like, isn't comfortable, not even your style. That starts to get depressing. Time for some modifications. So who cares if you make your "GMC" look like a "ferrari". Sure off road vehicles can be loads of fun, but so can a curvy sports car

I find myself asking myself, what kind of vehicle do I want to drive? Which is an authentic expression of me and my style? And why does it even matter what others think about how I have "tricked out my ride."?
We are raised to feel socially insecure. It's a tragic side effect of media culture. Everyone is effected in different ways, that's how they sell things.... marketing 101.
Some of us however are much more hypersensitive to everything and all that gets amplified. We are aware of the silly games people play around gender and sex and know we are something more. Something that can't be contained with labels.
Currently, I am "not transitioning" mostly out of fear. I have social and career challenges hanging me up. I don't have a ton of money anyway. I had panic attacks from the fear ahead of getting my wisdom teeth out, the idea of surgery on several areas of my body freaks me out. I am physically very hypersensitive. Extremely body-conscious. Aware of a distracting amount of my internal processes. I will be acutely aware of every detail of any procedures done to me. I'm going to need to hire a leonardo da vinci. Not so much for the outward appearance, that would of course help, but I am so sensitive, i want someone who is an absolute master in the field of reconstructive surgery. I can over-obsess on fine details of my body, a mistake would make me insane. Even if it is an invisible, sub surface flaw in workmanship. My minds eye will zero in it and distract me from everything.
I'm not in a situation where I can do this in a hurry anyhow. And I feel I really need to cross-examine myself and check all the details of such a process. I don't take scalpels lightly.
I hope to just gradually shift from one state to another. My hair is growing out quite nicely, I am blessed with no balding at 45. I have a naturally androgynous build and have recently returned to my teenage body size

.
Most of my insecurities about my appearance are actually age related rather than gender. I might even not need face work beyond skin care.
But I am isolated socially. This is actually quite HUGE progress for me coming up on a forum like this. Not long ago, I spoke to NO-ONE about this subject. I have bottled this up very tightly for a long time.
baby steps.
and sometimes it takes a while to commit.
