Alloflux, is when one usually feels allo- attraction (allosexual, alloromantic, etc.), but fluctuates along the corresponding attraction spectrum at times. It means that there is a fluctuation in ones allo- attraction.
Alloflux can be used for all forms of allo- attraction.
For example: If someone were alloflux in their sexuality, it would mean that they would feel allosexual at most times, but then there would be times when they identified more with asexual.
