Absorsexual

Absorsexual is a sexual orientation in which one absorbs the orientation of the people around them. As one is around more people, more sexual orientations are added to one's own, and even after the people leave, one still feels their sexual orientation.

These sexual orientations remain until one reaches a "maximum", at which point their orientation becomes a blank slate and reverts to a single "base" orientation, which can be any sexuality, including asexual. For some people this "base" orientation may be different each time.
