Ahem...
Like Micki, I had testicular oddities. Undescended, and effeminate appearance into my teens due to no puberty. I was given testosterone injections starting at age 15 "so you'll grow up right." All of this may have been due to DES exposure in utero, as I have a number of other common characteristics with DES sons, as well as knowing my mother did take DES.
Oh, and I'm a transgender person.
I'm not 'appropriating conditions to justify transness', just providing interesting background like others have.
I am what I am, a transgender person in transition from male to female. How I got here doesn't make me "less transgender than thou", or similar such things I've heard spouted from time to time. I'm me, and I have to learn how to be my true self going forward. I'm here on this site to help myself do that, and share with others.
That's nice that you believe you've never been clocked since starting HRT, but it is an experience that MOST of us have had as some point or another, and it can be a huge reality check and a real "slap in the feels". It can be enough to make us doubt ourselves. Being clocked also doesn't make us "less transgender than thou", it just means we have to work even harder as a matter of survival. Yeah, not passing is a survival risk in today's world, where "Trans-panic" is an allowed defense for crimes against us in 49 of the 50 US states, and we are targeted for political gain.
It sounds like you have been very fortunate in your transition. Please understand that not all of us are so fortunate.
