If you ask me, gender is actually a 4D spectrum.

A zero-dimensional understanding of gender is binary: you either have a p♂int, or you d♀n't.

Many people with a spectral understanding of gender can only see the first dimension, X, which is a simple line from man to woman. For them, this is a revolutionary concept, even though in reality this conception of non-binarity challenges old beliefs the least.

Some people will see the second dimension as well, Y, which goes from genderless to fully gendered. When I was questioning, I would see "gender quizzes" which used this type of still-rudimentary two-dimensional system.

Even fewer people will see the third dimension: as you travel through the Z axis, you will see that gender needs not be founded on genitals or societal conceptions of masculinity and femininity, but can be founded on anything. You are now entering the xenogender zone.

Finally there is the W axis, which is time, i.e. that gender is not static. You could conceive of a fifth dimension as well, which would be that gender is not necessarily predetermined, and you could conceive of even higher dimensions than that, but all that isn't really too necessary IMO.

In any case, with these four dimensions in place, one starts to see that gender extends infinitely in every direction, and that one's own gender needs not be a single fixed point (well, technically a straight line through the W axis), but can be a triangle, a spheroid, a tesseract, a klein bottle, literally any shape imaginable — and gender-space can even fold in on itself to create wormholes and apparently non-contiguous shapes.

Cis people's brains fry at trying to imagine all of this, in the same way that most anyone's brain would fry at trying to imagine ten-dimensional space. The long and short of it is that anything goes and it's pointless trying to quantify non-binary identities as simple coordinates.
