The opti-genitalia-queer flag, designed by Zarya Lukatyanobski in 2004.

Opti-genitalia-queer (sometimes formatted as optigenitaliaqueer or OGQ for short), is a type of gender fluidity characterised by the individual's tendency to alter their gender to that of the genitalia they are viewing, hence the name. This means that OGQ individuals:

  • Become male upon seeing a penis or testicles.
  • Become female upon seeing a vagina.
  • Are agender when genitalia is not within their sight.
  • Are bigender when genitalia from both binary genders is within their sight.

The phenomenon of OGQ was discovered in 2002 by Russian scientist and gender studies expert Zarya Lukatyanobski, who was the first to identify as opti-genitalia-queer, and also created the flag that represents it.

Some members of the opti-genitalia-queer community, dissatisfied with their orientation, have trained themselves to be able to mentally visualise an image of their desired genitalia so vivid that they are able to become the gender that corresponds with said genitalia. As a result of this, they are no longer OGQ, instead being classified as neuro-genitalia-queer, or NGQ for short.

Because OGQ people are always the binary gender that corresponds with the genitalia they are viewing, it has been reported that OGQ individuals spend abnormally long periods of time observing their own genitalia, as this is the easiest way for them to become comfortable with it. This practice frequently leads to excessive masturbation in OGQ people, and as a result of this, the OGQ community often suffers from acute social stigma and in extreme cases even blindness as a result of their habit.

OGQ individuals who are blind often struggle with their orientation, as they are unable to progress past the initial stage of being agender as a result of their condition, although many of these people find solace in becoming neuro-genitalia-queer, or alternatively even proximi-genitalia-queer (PGQ), meaning that they change genders by coming into physical contact with the corresponding genitalia. As PGQ individuals are constantly in contact with their own genitalia, however, people often find it hard to distinguish between those who identify as PGQ and those who choose to identify as cisgender.
