Alterous flux or Altflux describes someone who experiences fluctuating alterous attraction. An altflux person may feel strongly a-alterous at times at times or grey-alterous at others. An altflux person may even feel alloalterous at times.
Altflux can be used in conjunction with other identities, such as panalterous, homoalterous, or bialterous. An altflux person may also feel that their alterous attraction fluctuates between genders and not intensity, or maybe both.
