Fluid

In terms of orientation, fluid is a label some people use to indicate that their experience of attraction changes and/or varies over time. The changes may be in terms of which gender(s) they find themselves attracted to, or in terms of the intensity of attraction.

Abrosexual and abroromantic are more formalized terms that can describe a fluid orientation.
