Omniflux, omnisexualflux, or omniromanticflux is a sexuality and/or romanticality in which one can experience sexual and/or romantic attraction to all genders with variying intensity. The term flux indicates a fluctuating, variying intensity of a sexuality or gender when used in LGBTQ+ terms and labels. An omniflux person can have different intensities of attractions to different genders, while still being attracted to all genders. For instance; an omniflux person can feel attraction towards female-aligned/feminine-aligned genders more, compared to how much they are attracted to abinary/anonbinary genders at the time. The various intensities of attractions to genders can be expressed with percentages, e.g. one can say they have 70% attraction to male-aligned/masculine-aligned genders, 50% attraction to abinary/anonbinary genders, and 30% attraction to female-aligned/feminine-aligned genders at the same time. These percentages and/or intensities can change overtime, thus fluctuating, being flux.

The terms omniromanticflux or omnifluxromantic can also be used to indicate a romantic-only version of omnifluxity.^[1]

Much like the relativeness between genderfluidity and fluxfluidity, this term is a sub-category of omnisexuality, which means an omniflux person can just identify as omnisexual if they wish to do so. Labels related to the flux term are often used by people who find comfort in having a more specific label, so this may seem unnecessary to some, but is valid nonetheless.
