Yes, 100%
My feelings about gender seemed limited to a fantasy of being a woman, first of just having breasts, then for a long time also wishing I could turn into a woman. It was pretty manageable, just a secret I kept hidden and compartmentalized. This continued for decades.
After I came out to myself and started HRT, I had a period of joy mixed with fear, but I don't know that I could have called what I was experiencing "dysphoria." But as I started to actualize the female version of myself, I started to notice what I wasn't. In my case, I found the look of my face more and more disturbing. I found the thought of not passing as a woman to be much more than a disappointment at times. I often had crying jags over my situation, reflecting on how hard it was to want to be something I didn't ever think I could be.
As my body continued to develop, my "face dysphoria" continued to get worse. Trans friends tried to convince me that I was "fine" and that I should just relax and not worry about passing or what people thought. But they didn't realize how much pain I was in. It was like being an athlete who became disabled and was getting told they should go to the sports event and "just enjoy it."
Now that I have an affirming surgery scheduled, my feelings of discomfort have continued to grow and are a daily thing. I'm still grateful that I'm not suffering the way many others do, but I now understand a bit of what they're going through.
For me, my dysphoria emerged like that and became worse as a result of a new kind of self awareness.
