Mesosex: somebody who identifies with intersex people but not as intersex, and also feels perisex does not quite apply to them either. Meso- from Greek mesos (middle), to indicate that one feels in between having the intersex experience and the perisex experience. For example, people with reproductive disorders who feel they have common ground with intersex people but not so much common ground as to feel they are intersex.
There are conditions like PCOS and Poland Syndrome that exist on a spectrum from definitely intersex to perisex-ish, and I hope this term gives people on the perisex-ish side of the spectrum more useful word for themselves than the current language of “intersex-adjacent”.
I want to be clear that people with conditions like PCOS and Poland Syndrome are completely entitled to call themselves intersex and that there is broad agreement within the intersex community that anybody with these conditions who feels they are intersex is intersex.
In coining this term I am hoping to validate and connect people who would otherwise call themselves perisex yet not feel it is quite accurate for them.
Mesosex people can have any gender, similar to how intersex people can have any gender.
In designing the flag our goal was to give an impression of something in between the intersex flag and cisperinormative gender colours whilst also including nonbinary people. The salmon background is chosen as a colour that is not quite pink, and the periwinkle ring is chosen for being not quite blue, but still reminiscent of the purple ring of the intersex flag. The white centre, put inside the purple-ish ring, is chosen to reflect how the nonbinary flag has white and purple in its middle.
The term and flag were workshopped with @scifimagpie. I had been thinking for a while that it would be useful to have a term for people who feel in between intersex and perisex, and these recentposts by@queercripintersex on identifying with rather than as not only convinced me there is actually an audience for such a term but also inspired me to get this done!
PS. If you are questioning if you are intersex, check out this post by @intersex-support with a big list of intersex media, which you can use to get a sense on whether you resonate with intersex experiences. (Also check out their FAQ! And their past posts! They’re really great!)
