    What tf is perisex

    It’s one of the words proposed by the intersex community to refer to someone who isn’t intersex, much like cis refers to someone who isn’t trans.

    The other words I’ve seen around are endosex and dyadic, and they all seem to have pros and cons and there’s not been a great deal of consensus about what word would work best.
