On genderfluid

I had been feeling femme back in young years, but kept it to myself due to conservative environment. And then many decades of 100% masc life suddenly turned to almost waterfall of "I want to be myself, woman at core" few years ago. And then AD medication made another shift - to genderfluid. Some weeks or months I feel just fine with masc me, and then other weeks or months I experience sharp dysphoria and wish to transition. I believe it's biochemistry which drives this pendulum but never had a chance to figure it out.
