Extersex

Extersex is a term for when one does not know whether they are dyadic or intersex. It could be because one feels as though they might be some form of intersex, but are unable to medically confirm it, or cannot confirm what intersex variation it is. It may also be for those who have a variation that may be considered intersex, but are uncertain if they want to identify as intersex.

History
The term appears to have been coined by Tumblr user xenoqueer on or before August 24th of 2018.

Etymology
Exter- comes from the word 'external,' which references that one cannot tell the depth of their sex traits simply from the outside.
