Over seven years now and counting, on HRT and still living and presenting primarily as male. That is a male with a B cup. For me, "Male Fail" is an impossibility at 6ft tall and balding since 14. Being a former fatty on top of the GD, I always dress in baggy clothes (guy mode only). A few times my wife will not so gently hint I should change my top or do something because "My tits were showing". One time in the grocery store some old guy was just staring at them/me. But nothing has ever been said to me, aside from my wife.
Within my TG group there have been a few cases over the years that the member was only fooling themselves that they still passed as a guy. Eventually they went full time
Over the decades I've been on/off low dose HRT for the much needed Brain Reset. Back then the "Prime Directive" was to try to be a "Normal"(ish) guy. After 2 failed transition experiments I saw no other option beyond the occasional CD'ing and plenty of distractions to keep the GD at bay. Each time on low dose within a month or so the noise quieted back down to a tolerable level. But "The Dream" was still there and I stayed on past that point. I stopped when I began noticing that things were taking a hit below the belt. Something in direct conflict with The Prime Directive.
The worse aspect of being on feminizing levels of HRT, finally having a body you can live in, and experiencing the shear joy of being out in the real world as the real you is the going back. Sunday nights were the most depressing and conflicting times when the nail polish had to come off. It is a BIG emotional drain after a while
