And in case you're wondering : yes, I did start a transition from man to woman, years ago, and it's not incompatible with the fact that, to me, gender/sex should be abolished entirely and thrown into the burning core of a supernova.
Because feminity exists and because I was more comfortable with performing the traits and behaviours commonly associated with it than the ones of masculinity, I did transition.
I do feel better in my body with less testosterone and more estrogens, or after some of the surgery I received. Of course, it did make it easier to perform feminity and that was a relief in itself.
But when I'm alone, at home, and I don't have to perform, those changes in my body still suit me. I like the texture of my skin, or my vulva or the way estrogens helped me reconnect with my emotions, or reshaped some sensations.
I'm so happy I had the opportunity to get rid of my Adam's apple. Always hated its shape and look and feel, way before I knew I was trans and wanted to transition. If I had been happy performing masculinity, I'd still hate my Adam's apple and want it removed. That was just dysphoria with a part of my body, not gender dysphoria.
The fact all these changes feel good and improved my life even outside of gender performing settings have nothing to do with feminity or masculinity, even if they happened in part because of a need to perform.
It's a question of body autonomy, not gender.
