@AncTreat5358 If it helps, I am trans femme genderfluid enby (non-binary).
But ... none of that is prescriptive, all those terms are descriptive, meaning that they describe best how I feel.
Sexuality-wise I am omni, but romantically I am lesbian, trixic (enby attracted to women), and enbian (enby attracted to other enbies).
Being genderfluid means that my gender can change depending on various parameters (situation, weather, partner, emotions, ...), thus I have defined a 'gender-at-rest', which is something neither male nor female, but also not a mix of both, it is somewhere outside.
Still, when you check out my selfies you'd assume I am a woman and I mostly, but not always, dress femme.
Passing has nothing to do with what you feel; I purposefully avoid "passing", by e.g. not changing my voice, and I have a very prominent Adam's Apple.
So, feel free to explore and don't let yourself restricted by words - assign meaning to words as you want and as they fit you best - as I said, they are descriptive, not prescriptive (and anyone who says otherwise should just shut up).
Also, we are all here if you need help or look for more questions/answers.
