An umbrella term for all orientations that are related to having little to no attraction on at least one attractional spectrum (these spectrums include sexual, romantic, platonic, tertiery, and others). It is sometimes abbreviated to anspec.
Sarah is asexual, Rodney is aromantic, Penelope is aplatonic, and Aric is anaesthetic. Though they all have different orientations, they all fall on the anattractional spectrum.
