Genderflux is a term for those whose gender fluctuates in intensity. It can be thought of as a form of genderfluid where agender is the base. Genderflux individuals can fluctuate from feeling 0% gendered (agender), to being 100% a given gender. In between those extremes include being slightly a given gender, (libragender), to being partially a given gender, (demigender) to being mostly, but not entirely a given gender, (paragender). For example, a girlflux individual can fluctuate from agender, to librafeminine, to demigirl, to paragirl, to fully girl.

Although genderfluid individuals may sometimes be agender, they are not necessarily genderflux. Genderflux individuals generally do not change gender, only the intensity of their gender. For example, a boyflux individual may only experience agender, boy, demiboy, and other varying levels boy. Someone who is solely boyflux will never experience genders that are not agender, boy, or partially boy. A genderfluid individual may experience agender, boy, girl, and any other genders. Although genderflux is a very specific type of genderfluidity the terms genderfluid and genderflux should not be used interchangeably.

If someone has multiple genders that fluctuate in intensity, they could identify as multiflux and/or multigender. If only a single part of one's gender is fluctuating, while the other part is static, they may identify as demiflux. Someone whose gender is fluid and fluctuating at the same time may identify as fluidflux. If only one part of one´s gender is fluidflux, with the other part being static, they may identify as demifluix.

Genderflux individuals sometimes also identify as non-binary, genderqueer, and/or transgender, if they wish to. The suffix -flux can be applied to any gender to indicate that the intensity of that gender fluctuates.
