Dyadic

Dyadic, also known as Perisex, Endosex, and Juxtasex is a term used to refer to people that aren't intersex, or someone who was born with sex characteristics which could be categorized into one of the binary sexes, and do not have any sort of chromosomal or hormonal deviation which is realized later in life. Dyadic people can have any gender identity, including transgender and non-binary.

The term is not an identity by itself. It was created by the intersex community as a way to describe those who are not intersex, to avoid referring to non-intersex people as "normal/natural," which implies that intersex people are not normal or natural. It's used in the same way the transgender individuals use the term cisgender to refer to someone who is not trans.

Terminology
There is no consensus on what terms should be used to refer to non-intersex people. The most well known terms are dyadic and perisex, however some intersex people dislike the use of the term term dyadic, because it meaning "two" reinforces the sex binary. Other intersex people dislike the term perisex because it was created by non-intersex people who dislike being called dyadic. The term intrasex is the most logical word for non-intersex people, however that is not used because of how similar it looks and sounds to intersex. The terms endosex and juxtasex were created as alternatives but these are not widely known. Some intersex people prefer endosex over dyadic.
