Duosex

Duosex (from Latin, duo- "two" and sex) is a sex dysphoria pattern descriptor also used as a gender identity under the non-binary and trans umbrellas.

History
Duosex was coined by the user Chapter-Salty in July 2021 first on the subreddit r/truscum and was later adapted on r/trunb as an official term through polls. The term was then shown to the users outside of r/trunb in August 2021.

The flag was created and proposed on 29 August 2021 by r/trunb mod M3lonKat and then voted for in a poll together two days later with the transX and nullsex flags.The colours and their significations were originally suggested by user elhazelenby.
