Dyadic

Dyadic, also known as Perisex, Endosex, and Juxtasex, is a term used to refer to people who are not intersex, meaning people who were people born with sex characteristics which can be categorized into one of the binary sexes, and who 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.

Dyadic people fall into one of two categories:

1) AFAB dyadic.


 * Have XX chromosomes.
 * Was born with external genitals which were identified as a vagina/vulva.
 * Was born with a uterus and ovaries.
 * Upon natural puberty, experienced development of secondary sex characteristics indicative of increased estrogen levels.

Dyadic people that meet these qualification are typically AFAB, although, not all AFAB people are dyadic.

2) AMAB dyadic:


 * Have XY chromosomes.
 * Was born with external genitals which were identified as a penis and scrotum.
 * Was born with testes.
 * Upon natural puberty, experienced development of secondary sex characteristics indicative of increased testosterone levels.

Dyadic people that meet these qualification are typically AMAB, although, not all AMAB people are dyadic.

If someone meets some, but not all the requirements of a certain category, or meets some requirements in both categories, they can be considered intersex. If someone is born dyadic, but changes their sex characteristics later in life (either through surgery or HRT), such that they no longer meet the qualifications listed above they may identify as altersex and/or transsex.

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" or "natural," which implies that intersex people are not normal or natural. It is used in the same way that transgender individuals use the term cisgender to refer to someone who is not transgender.

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, but it is not used often because of how similar it looks and sounds to intersex. The terms endosex and juxtasex were created as alternatives, which some intersex people prefer, but they are not widely known.
