Duosex is an identity linked to both the male and female sexes.
The only requirement to be duosex is to feel both male and female, regardless of gender. Duosex is similar to Bigender, but duosex is a connection to male and female, while bigender is a connection to any two genders. Duosex individuals can be any gender, whether masculine, feminine, neutral, xenic, or any others. This is because males aren't always men, and females aren't always women.
History
Duosex was originally proposed on r/truNB on Reddit some time around July 15. 2021. Because it was made by truscum, FANDOM user atlasjv/tumblr user mysticsnowstorm decided to reclaim the term on August 16, 2021, making it inclusive and giving it a flag. The reclaimed version of duosex has no association with truscum.
