Masculine of Center -- the term

[Medusa]

I would also submit that Masculinity and Femininity aren't necessarily on opposite ends of the spectrum or opposite sides of a circle from one another.

Attempts to diagram gender often end up with a big "M" on one end and a big "F" on the other end with multiple identities getting plotted somewhere in between. This is hierarchal to me and often ends up feeling erasing of Trans identities.

I think in a perfect world, gender would be a 3D pool where all of our various molecules and atoms bump and collide into one another, exist within and outside of one another, and gain strength and power from one another.
