Is there any system of describing sexuality not relative to own gender? The terms "biromantic" and "heterosexual", which I currently use myself, break down if I were to go agender. Like, what is "heterosexual" even supposed to mean if I don't have a gender? Sexually attracted to genders not your own, which in my case is all of them except agender? In that case, that's just pansexual minus agender, no? But that... huh?! That doesn't match my recorded patterns of attraction at all.
See, the standard system breaks down when talking about nonbinary genders, which I guess is what I'm trying to become. And God help me (not that he would. Intolerant motherfucker. Or maybe my parents are intolerant motherfuckers, and they're just using God as a mouthpiece to "justify" said intolerance) if I were to try to describe attraction to nonbinary people as well. I don't have the slightest clue how you're supposed to describe that.
I could solve the first problem of it making no goddamn sense by specifying it relative to my birth gender, but that feels like a hack. That's probably how I'll describe it to others, but I'm talking about the internal bookkeeping that I'm doing, which can be as complicated as I want. The second problem, describing attraction to nonbinary people, needs a new system to describe it. All I want is a system that's as universal as possible for my own purposes.
I'm probably gonna ask these hard questions as I get to grips with the idea of transitioning. Expect more later on.
