It seems I'm somewhat of a rebel when it comes to 'passing' - at least in the fairly stereotypical definition that exists here.
Let me start by saying I 'pass', I've not been misgendered in so long I forget the last time it happened. I'm fine in stores, in public and even in bathrooms. I've been asked for tampons often enough now that I carry a few around with me. I don't get funny looks and I certainly haven't heard any one making any odd comments.
So why am I a rebel? I refuse to do a whole bunch of things that are apparently 'necessary' for me to do in order to 'pass'. I've been told by other members here that I will require FFS in order to pass. Guess what? I have no interest in FFS. The apparently 'masculine' features I have are all present in all the other women in my family - and no one accuses them of being men. I may not be a stereotypical beauty, but I've blended into society as a woman.
There are whole threads dedicated to voice and how you have a voice that is pitched at a typical female level in order to 'pass'. I've done no work to change my voice and it does me just fine - I've been accused of being lazy because of this. Funny thing is, it's only people here that say my voice doesn't pass. People I know in real life all give it a pass, as do members of another chat room I'm a member of. None of whom have any reason to lie to me about it either. I don't get any funny looks or changes in attitude from random strangers when I use it in public either. I guess it's a case of 'If it isn't broken, don't fix it.' My therapist, who has extensive experience with trans people, has also commented on my voice, he gives it a pass too.
I've not really done anything to change how I move or other physical mannerisms - I've had no need, I've always moved like a female and had female mannerisms. This is something I previously got quite a lot of grief for - both from family/friends and strangers. My family and friends understand why now.
I transitioned to be me, the me I always knew was there, just hidden away. And in the bit over 2 years since I came out and started my transition, I feel I've done pretty well. On a day to day basis, I 'pass'. I'm never going to be stealth, I have too many old friends and my entire family still in my life, but friends I've made since I started transition, and who know my past, have commented that they could not imagine me ever being a man.
