I have another cis woman's story of being on a transitioning dose of testosterone, mine:
I'm a detransitioning woman who thought I was a trans man before. When I first went on testosterone it felt like a relief. That my mind got less cluttered and my emotions easier to manage, and I liked the physical changes that made my body more masculine. However, the reason I liked the changes was because it was (subconsciously) an escape and the testo basically fed my desire to escape being a woman and all the hurt I had endured for being female. It was a relief, but not because of a gender/sex mismatch and that's why it took me so long to discover, but eventually it did catch up with me.
I was on testo for 6 years in total before me actually being cis caught up with me. Leading up to that moment, a few days before it hit me, I started getting dysphoric feelings about my male traits and seeing a man in the mirror. It confused me a lot. When it actually hit me and I knew what was going on, I got instantly super dysphoric about my male sex characteristics that T had given me over the years, while I was suddenly fine with being female and wanted to look female again. Basically my dysphoria went reverse upon realisation.
It took me a while though, before I came to the conclusion that I want to go off testo. I thought that I like my new fat distribution and the psychological effects, the higher libido and not having periods which are all reversible effects. And I'd been on it for so long now it's not likely to cause more masculinising effects. I made a list of pros and cons that I kept going back to, to tweak on, and over time I had less and less reasons to stay on the hormone. And now I want to go off it.
Now, I'm still not complaining about the fat distribution and would prefer it to stay this way if that was possible without continuing taking the T. I actually like my deep voice despite it totally sounding like a man's voice. What makes me dysphoric concerning the changes I got is the excess hair growth, facial hair, excess sweating, "manly" body odour, and vaginal atrophy that I have to take meds for. The changes not mentioned I'm either okay with or actually like.
So that's how I reacted to starting and being on hrt as a cis person. But I am not every cis person or a very typical one. If I had gone on T without first thinking I was a man, or for any other reason than being trans, I likely would have reacted very differently to it. For the past 5 years, continuously, my T levels were always in the upper healthy male range, btw. The first year I took it I self-medicated and had no idea what my levels were.
