Dyadic flag by pride-flags-for-cishets
Dyadic is a word used to refer to people who are not intersex. Dyadic people were born with sex characteristics which could be categorized into one of the binary genders.
Similar to the term cisgender, it was created to avoid referring to non-intersex people as "normal/natural," which implies that intersex people are not normal/natural, which many members of the intersex community take offense at.
