Nebulesbian (pronounced ne-bew-les-bee-an), is an identity with two definitions.
The original, which may be typically used, is exclusive to neurodivergent individuals who are aware they are lesbian, but have nebulasexual and/or nebularomantic experiences. Traits that are caused by one's condition might impact how they feel about their sexual and/or romantic attraction to, but have no effect on whether or not their attraction is only towards individuals who do not identify as male.
The second, which is also exclusive to neurodivergent individuals, describes a person who is lesbian-oriented and does not wish to explore their attraction or identity further due to neurodivergence.
History
The term was coined by a user who wishes to go by "QMCR" due to disowning their inappropriate username. Nebulesbian was heavily inspired by nebulasexuality, nebularomanticism, and lesbianism. It is essentially a combination of all or two, one required to be lesbian - the term was officially posted onto the LGBTA wiki in September 7th, 2021, with no known resources that help describe nebulesbian further.
The page is currently awaiting on QMCR's further description.
