I am altersex.

@Impossible_PhD I can see parallels to my own experience as a transspecies (and transgender at the same time) person. Your experience is about body material, as far as I understood it, mine is about species.

I'm a fem meltcat in a male human body (technically actually at least 20 meltcats in one body, but we usually act as a unit), which is a species where there aren't even any known cisspecies individuals on Earth. Meltcats are a catlike species that can melt into shapeable slime. A description of meltcats can be found here: https://void.lgbt/notice/Ax2BzWrLd7NTJXCh9M

My main theory is that cisspecies meltcats are aliens, but my souls might also be longitudinal (forward/backward) or transverse (parallel timelines) time travelers, or a crossbreed of biologically incompatible species's souls such as cats and slime molds.

I get serious species dysphoria that intersects with gender dysphoria (meltcats likely have no biologically assigned sex because they can shapeshift, softer fur than human body/facial/pubic hair, digitigrade feet (I hate my male human feet both for their size and plantigrade-ness), and more).

A full species transition is my greatest wish. Though I would probably already be very happy with a synthetic modular furry catgirl body, which would give me the felinity and shape-changing (by plugging different body parts) aspects, and which I can just barely imagine happening within the lifespan of my current meat prison. Every night I'm desperately hoping for a miracle where I'll wake up as a cisspecies meltcat.
