Well we all have our ideas, opinions and what we feel we need to do in order be and feel who we are. To me it is more of a psychological/mental/spiritual event than anything else. As for the physical part? For me, it doesn't really matter too much right now and never really has. Nature dealt me a pretty good hand even though at times trying to be a boy growing up was hard. I am a feminine guy or masculine girl. My facial features can go either way. I see a quite a few ciswomen that are facially more masculine than me and even saw one on the news yesterday morning. Small hands and wrists. Legs that are shaped more like a female than male with very little hair that grows on them and as a guy always got made fun of but secretely flattered. Oh, those love handles that always got me pegged as fat and out of shape being a guy even without a gut, the more weight I lose the more I notice there is actually bone under there. Gynecomastia gives me little ones that don't go away with the rest of the weight. I saw my reflection full length in a glass door yesterday and was quite surprised. It seems the more belly I lose the curvier my hips get. I forgot how strange I was shaped as a guy without being overweight. Not to mention the tone of my voice.
So with all that said, sorry Anatta, I know you like short answers

but is there such a thing as "mind over matter"? Are parts of my body just an anomaly? Since I have felt more female than male inside since first memories regardless of my genitals, did my consciousness or Spirit have an effect on theses things pertaining to my body? I read the thread about DES sons. Looked it up and they stopped using it in '71 and I was born in '67. I asked my dad and he remembers her being given something because she had a miscarriage before me and after me so I was a pretty high risk pregnancy for her. But his memory isn't that good anymore. Never had children either and as a guy I was a dog, so something definitely wrong in that area too. As a matter of fact if it wasn't for the testicles hanging below a lot of time my outie is an innie, just not all the way in but I definitely wouldn't have a bulge.
So for me it is definitely more of a psychological/spiritual thing that happened a long time ago and am getting more comfortable and actually liking with my body without all the fat I used to have. But if I ever fall in love, which is a possiblity lately, I would take it farther with HRT. Even though it isn't an issue I might even go that route anyway just for myself. At times I am full time but not in my own backyard. There I still pretend to be a guy.
