DISCLAIMER: Sorry for responding to a guy-thread

Hmm. Perhaps it has to do with shifting expectations.
when I started out, nobody ever thought I was female. Luckily, HRT has been like a miracle drug, and I've changed rapidly. But this goes in phases, both physically and mentally.
When starting out, my wish was NOT to be seen as a man anymore, not to have his crippling social dysphoria that comes with society's wishes for male behavior. To that end, a lot of results are satisfactory. I was equally OK with being misgendered from time to time, even being a non-passable transwoman was better than being a man.
After having been on HRT for about 13,5 months now, I can say that goal has long since been fulfilled. Last May, I started to notice I had passing privilege on first sight, aka walking around and while having short conversations. So, my wishes slowly adjusted itself, from being OK with being non-passable, I started to want to be passable at second glance.
That moment came last August, when I discovered some old friends didn't recognize me at all anymore, and others who didn't know me even didn't notice after having had a two-hour conversation with me. That taught me the voice, face and general appearance were OK.
However, there was still this rather masculine waistline which, of course, can be hidden with the right attire. Together with the 24/7 passing came the go-ahead from my insurance company for SRS. This shifted my views and desires yet again, because I wanted to be passable without wearing any clothing as well! As my transition went on and my self-image changed accordingly, so did my feelings to have 'proper' vaginal intercourse with a man grow. Exponentially.
Luckily, I've been noticing my waistline is slowly decreasing in the last few months, and my hip-circumference slowly increasing. I've even hit this point a month ago, where my ass was definitely wider than my waist. Basic hourglass-figure established. However, there's still way too much masculine abdominal and visceral fat there.
Point is: what made me happy before (HRT, limited passing, full passing with clothing on) isn't enough anymore. Now, I'm starting to get an appetite for what's REALLY possible: SRS, a female shape and most of all; MEN! This also influences my dysphoria, being read as a girl just doesn't cut it anymore, since together with all of these realizations came the innate knowledge: I'm already a woman.
So now I want my entire body to reflect that truth, and I want for men to adore me just because of that female body. I'm not there yet, but it's getting closer. My dysphoria is shifting along with my preferences. Generally, my dysphoria is less, but the dysphoria about specific body-parts that I deemed "OK" is getting worse now.
- just my two cents!
