Should not be confused with Genderspace
Spacegender is a xenogender and neurogender gender that is based off of the feeling of gender being void-like while also being never-ending and feeling full but empty at the same time.[1]
This term is mainly intended for neurodivergent individuals, but can be used by anyone who identifies with this gender.
History
The term was coined by an anonymous user on a carrd site, and it is unknown when the carrd was made.
