Gendersylph

Gendersylph also known as Genderfeor, Genderfoan, or Genderfen is a form of genderfluidity in which someone is exclusively (or nearly exclusively) fluid between xenogenders or otherwise uncommon identities. Someone who is gendersylph would never or very rarely identify as something within the binary. They almost always identifies as something non-binary. This identity can change at random and change in intensity.
