Unusexual is when someone experiences sexual attraction to a single gender that is different than their own; this includes attraction to the "opposite gender" (if they're a binary gender). For example, a woman being attracted to only agender people. Some enbian people may identify as unusexual as well if they're only attracted to one gender on the non-binary spectrum.
Similar terms include monosexual.
