Xumsexual, also known as pendosexual, is the state of never being satisfied with one's sexual orientation, no matter how well it fits, due to self-doubt or identity issues. This causes one to compulsively search and seek out something that fits even better- to find "the orientation" or "the one truth"- though one will never be found due to A) One's neurotype. B) Words will never be able to describe one's orientation. C) One's orientation is paradoxical. This inability to find a "one true orientation" frequent causes anxiety and doubt and can even cause the label xumsexual to feel imperfect to the individual.
This term is exclusive to neurodivergent people. It was specifically coined with people with anxiety disorders, OCD, and OCPD in mind. The term implasexual exists for neurotypical people who relate to this experience and don't want to appropriate.
