Highly relevant terms

Extersex - "[A] term for those who do not know whether they are dyadic or intersex. It could be because one feels as though they might be some form of intersex, but are unable to medically confirm it, or cannot confirm what intersex variation it is. It may also be for those who have a variation that may be considered intersex, but are uncertain if they want to identify as intersex." - @themogaidragon

Inter-Questioning - "a term for anyone who is questioning if they’re intersex, for any reason. (Whether it’s due to one’s physical body, familial experiences that imply one is, or possibly simply a mental feeling that one is intersex.)" - @eldorr

Quoisex - "[An] umbrella term for anyone who doesn't quite understand their sex or doesn't want to define their sex." - LGBTQIA+ Wiki Note: I understand this as more general than extersex, and would include people questioning if altersex. See the wiki entry for subtypes (quoigonadal, quoichest, etc)

Altersex - "An umbrella term to describe having or wanting primary or secondary sex traits/characteristics that do not align with the binary sex model that a significant portion of society has adopted. It is primarily used by those who are not intersex and are trans+ and wish to or transition specifically to have a body that does not fit the aforementioned sex model." -@intersex-questions Note: Being altersex does not make somebody intersex. I include it because many people questioning their intersex status realize this is what they're looking for.

Anisohormonal - "Aniso (unequal/uneven) + hormonal (relating to hormones). An individual who has an imbalance of hormones for any number of reasons. Such individuals may or may not also be intersex." - @sproutflags Note: includes non-intersex variations such as diabetes.

Subtypes of intersex people

Note: In my experience most people questioning if they're intersex have a hormonal intersex variation like PCOS, so I'm skewing towards this accordingly.

Dysgonadal - "[having] dysfunctional gonads. This includes agonadal (no gonads) and hypogonadal. Also known as gonadal agenesis/dysgenesis, dyssex and nullogonadal/asexed (null sex or avaginal/aphallia)." - @arco-pluris Note: contrasted with eugonadal - "people with functional gonads (reproductive cells). Includes hypergonadal (hyperfunctional gonads)"

Interhormonal - "Someone who is intersex and anisohormonal and/or feels that being intersex has impacted their identity as anisohormonal in some way and/or that their identity as anisohormonal has impacted their identity as intersex in some way." - @sproutflags

Intermeer - "a term used to describe all intersex variations that are caused by an overproduction of horomones (testosterone, estrogen, or both.)" - LGBTQIA+ Wiki Variations include: AES, FMPP, PCOS. Part of The Autre System for categorizing intersex variations.

Intermindre - "a term used to describe all intersex variations that are caused by a lack of horomones (testosterone, estrogen, or both.)" Note: The wiki lists AIS and EIS as examples although they are not due to a lack of hormones, but rather a lack of sensitivity to them. Part of The Autre System for categorizing intersex variations. See the wiki for more subtypes. Thank you to anon asker who pointed out the AIS/EIS issue.

Mesosex - "[A] person who has an intersex variation, but one which does not conform to perisex (non-intersex) ideas of what intersex is. For example, people who have intersex traits that are considered "mild", or who have variations such as PCOS Hyperandrogenism and Poland Syndrome." - @ipso-faculty

Intersex Terminology Masterpost by @intersexfairy

Interdynamic : a term for individuals whose secondary sexs characteristics do not match with the typical secondary sex binary.

this term was coined by an intersex person (me) and is exclusive to intersex individuals.

this is a miscecanis/misceverse term.

In my version of Omegaverse, Omegas are the only dynamic that experiences regular, visible heats. Those heats are periods of hightly heightened arousal and fertility (of the getting pregnant kind - an omega in heat is extremely unlikely to successfully impregnate anyone) combined with heightened pheromone production. It's typically tied to many unpleasant symptoms such as pelvic pain, dehydration, or digestive system problems.

Normally, an omega in the temperate zone will experience between 1 and 4 (usually 2-3) heats a year between spring and summer. The heats may vary in length depending on both the omega and their environment. Close, prolonged contact with pheromones of an alpha in rut is known to shorten the span of a heat to as little as 5 days, while really unlucky omegas might spend nearly three exhausting weeks in heat. It's common for omegas without alpha partners to buy or borrow clothes from rutting alphas in order to shorten their heat.

Your typical omega will also experience heightened virility during early winter. This is not a distinct state the same way heats or ruts are - it has no strong symptoms or sharp borders, it's just a hormonal peak. Omegas will experience heightened arousal during this time, as well as some water retention, but it will be nowhere near as noticable as their heat was. Because of that, many people don't even know it exists in normal omegas.

Sometimes, omegas will have this cycle reversed. They will experience heats (most often 1 or 2) during late autumn or winter and a longer, more intense virile period during spring or summer. Sometimes, this phenomenon is triggered by traveling between different climate zones (especially different hemispheres) and temporary. Other times, it's related to deeper anomalies and permanent. People with permanently reversed cycles are called winter omegas.

Winter omegas have been traditionally associated with same-dynamic attraction and "alpha-like" personality/behaviour, resulting in many alphas treating them as competitors. This sometimes results in insecure alphas trying to throw a wrench in the works for winter omegas, but many of them embrace their identity and differences nonetheless.

Winter omegahood is sometimes caused by blindness - awareness of changing light levels throughout the year plays an important part in regulating the estrus cycle of temperate zone omegas. However, many winter omegas are able-bodied.

Efforts to permanently "correct" their natural heat cycle fail more than 90% of the time, and treatments might be more harmful than the condition itself, so the best course of action is just accepting winter omegas as they are, providing them with everything they need during both their heats and virile periods. Of course, winter omegas may choose to go on heat supressants, but that's a matter of personal choice - most of the time, they're medically unnecessary.

(normative in quotations b/c I think the secondary sex binary and the way it's enforced is Bad, but I'm not sure of the best alternative language!)
