why do you want to undergo HRT?
@lia_kim mhm I guess you do you. I'm enby and have no issues with any gendered pronouns (even though I secretly prefer she).
But to circle back to your initial question. I guess you are as cis as you want (or not want) to be, and wanting to undergo HRT doesn't change that at all :)
FWIW: Euphoria came first, for me. I developed (small) breasts because of a drug reaction. Instead of being appalled, I was elated. That was my euphoria moment.
Realizing I was trans came soon thereafter.
