Aivotsex

Aivotsex is a sex that is specific to systems. It is a term used to describe non-human alters within systems who have sex characteristics that are not describable as male, female, or intersex. This term may be used by any non-human alter to describe the sex characteristics they have within their inner world. For example, a non-human alter who is partially or fully an animal may have something similar to a faunagenital, making them fit aivotsex better than terms for human sexes.

This term is only to be used by those who are non-human alters, and is not to be used by anyone outside of a system. One with this sex may or may not identify as aivotgender as well.
