My primary/most preferred is demiboy. How far I get into the specifics depends on who I'm talking to. I'm technically bigender, although because of its association/assumption of boy&girl (which are not my two genders), it's not part of my identity or something I indicate without clarifying.

I basically experience my genders as two layers. The base is an aporagender and colour gender (white), and on top of that is flux-boy (something that was briefly my preferred identity/term). Basically, a boy layer that fluctuates in intensity, so sometimes more of the base aporagender is "visible" (experienced/noticeable) through/past it, and sometimes less.

For me, the aporagender is kind of like a blank canvas, which might seem like nothing, but to people familiar with art, the mediums/materials you use have an impact on the art. Even if there's colour covering it up, a canvas is very different than a sketchpad, and still has texture that comes through. When my boy gender is at low intensity, it changes the overall experience because of how the "canvas" comes through in the negative space.

I initially thought I was binary, and just identified as FTM, when I started figuring out I was non-binary, I preferred transmasculine at one point. Most of them are still accurate, and I have a certain fondness for them even if they're not a primary part of how I identify anymore.
