but experience all femenine genders and they each fluctuate evenly, so that I experience all of them always, and they each experience a percentage out of one hundred, and all of them always add up to 100%?
I dont see why not
Alice, Screech they/them
Yeah, as long as you fit the “I have multiple flux genders at the same time”, you can be multiflux. You would probably land on the “they’re somehow linked in how they fluctuate” thing.
And if you’d like to be even more precise, you can always coin a subset !

If you feel like the term fits you, ofc you can be multiflux! 
And like Neo said you can always coin a subset if you want!
