Demiflux

Demiflux is a form of demigender where one part of one's gender is static, and the other part fluctuates in intensity. For example, the static part could be female, but the other part could be male. The male part can fluctuate, going from fully male, partly male (demiboy), to no intensity (agender), while the female part is always present and does not fluctuate.

Demiflux people may also identify as multigender. The static part can be any gender or combination of genders. The fluctuating part can be any gender or combination of genders. If it is multiple genders one may also identify as multiflux.

It could also be a demigender identity fluctuates. For example, a female demiflux person may feel demigirl most of the time but it could fluctuate between agender and demigirl.
