Xenogender

Xenogenders are non-binary gender identities that can best be described with how they related to things or beings that most people don't think of as having to do with gender such as animals, plants, things, or concepts, as they do not have to do with gender. They are not related to masculinity, femininity, neutrality, or terms commonly used to describe gender. It is sometimes describes as any gender that "cannot be contained by human understandings of gender". People who identify as a xenogender gender may call themselves xenic.

When xenic people talk about their gender experiences they often find that there aren't any words for their experiences, this is called a lexical gap. In order to fill that gap xenogender people often use metaphors to compare their gender to things that are understood. The term xenogender is used as an umbrella term for any non-binary gender that are primarily defined by characteristics with no relation to female, male, neutral, or other terms traditionally used for human genders.

When described, xenogenders often fall into one of three categories:
 * Nouns and Archetypes: Instead of saying how one's gender relates to masculinity and femininity, one says their gender is, or is like, a kind of animal, an imaginary being, a part of nature, an abstract concept, or a symbol. These types of genders are sometimes called noungenders.
 * Synaesthetic Perceptions: When a gender is described using things like texture, size, shape, time, light, sound, or other sensory characteristics. These can often overlap with noungenders. They are sometimes called aesthetigenders.
 * Neurodiversity: When one's mental illnesses, neurological conditions, or neurodivergence, are an inseparable part of their gender identity. These are called neurogenders.

History
The term xenogender was coined by Tumblr user Baaphomett in 2014.

Flag
The xenogender flag was created on January 15, 2017 by DeviantArt user Pastelmemer. The central symbol is the astronomical sign for the asteroid Iris, a Greek goddess of rainbows. The colors chosen are common colors present in iris flowers. The central stripe is yellow, a common non-binary color. It is opposed to purple, which usually stands for androgynous non-binary genders which have some combination of male and female identities, yellow is often used to symbolize genders which have nothing to do with the binary in any way, which includes xenogenders.

Etymology
The prefix xeno- indicates some having to do with aliens, which is appropriate as xenogender are unrelated to human genders.
