That was the opposite for me! I thought I was genderfluid for a few years, then all of a sudden my dysphoria was acting up horribly bad and I started to hate my name and didn't know what the heck was going on. Then before I knew it BOOM! Universe dropped the bombshell of "You're Trans!" on my head lol. That was a wild day... got hit in the face with a duck and everything...Yeah. For a good few years I had thought I might be Trans. Didn't fit right though still. Figured out just recently that I'm actually probably gender fluid instead of one specific gender.
