I am working on that as well as trying to limit other less desirable actions. I also spend far too much time being super self aware wondering if that last gesture or word choice was feminine enough or too fem, did it come off campy and overblown or was it what you would expect, am I walking correctly, do I even need to adjust my walk, there is not any hip wiggle in it but I do feel I have long walked from my hips and legs not my sholders.
I truly wish I had more a chance to hang out in social situations with just women, I feel everyone tends to adopt the gestures and actions of those around them. So ya I spend too much time in fact struggling to adjust things, which is not easy when hanging out mostly with the same mostly male friends, its so easy to fall back on old actions. To complicate that there are some aspects of who I have been that I am hanging on to that I like even if they may not be terribly feminine but I like them.
My hardest struggle is not really about passing its about how I think, mostly how I think about and treat myself, I agree with just about everyone that if i can just treat myself like I treat others, forgive myself for my mistakes, stop insulting my appearance, my weight, my hopeless love life, exc. I will be much better off, if I can convince myself to just accept peoples compliments and not assume they are just humoring me or think I am sick or wrong and just want to not upset me. If I can just be told "I love your hair and your make up looks good" and just say thank you and not spend the next 10 minutes argueing with them or myself about how awful I look.
Ok that all went off topic but ya your not the only one trying to work on the non visual side of this, I know a trans masculine type who has been presenting male for 3 or 4 years and I pointed out one day that they cross there arms in a way few men ever do, they knew about that and keep trying to avoid it but its a nervous habit, I then suggested they try harder to avoid it in the sweater they where wearing as the action sorta frames certain attributes they are trying to downplay. I personally have started crossing my arms the same way, mostly to push a little cleavage into showing off same action same result but one of us is looking for that result. :-P
