the multigender system experience is like identifying with genderqueer experiences outside of/contradictory to your body. Like cause you got alters who are not the same gender as the body... and you're like... why do i relate to transfem and femboy type experiences when the body is afab...? its cause your alters arent all cis, honey. nor are they all female. some are guys. and some exist in a feminine body, and therefore have an interesting male-centered genderqueer experience because they're guys who are also girls. external wise... we look like a girl, but on the inside, its not the same thing.
And for some systems, they see themselves as transmasc bc of that. Some male alters will have dysphoria in a different body, and that's okay. And they identify that way.
But for me, in my system, guy alters often see themselves as cis, so when those guy alters end up experimenting with gender, or relate to characters or people online who have feminine traits while being a guy, or have a feminine body while feeling amab, it can get really messy in here.
And I think to singlets/non-systems, that's an experience nobody really knows about. Even binary systems don't really get it. But we are multigender because we are sometimes multiple genders at once, multiple alters fronting at the same time, or an alter in a unique situation that makes them inherently genderqueer.
So shoutout to genderqueer, multigender, and nonbinary systems. I'm in your boat, it's weird to have a contradictory identity, but it's also kind of freeing. It's freeing to not really have to be binary and have to stick with one way of being. If I'm nonbinary, I can virtually do, and be whatever I want.
