Hello! I'm really obsessed with posting right now, but I'll try to even out my posting schedule sooner or later. So I've noticed on quite a few pages about demigenders that people have been confused about what was different about demigender, demiflux, and demifluid.
Demigender: Someone who is demigender partly (but not fully) identifies as non-binary. Some demigenders prefer the terms demiboy or demigirl. They may user she/they or he/they pronouns, but some demigenders use she or he plus neopronouns or nounself pronouns.
Demiflux: A demiflux person's gender flexes between cisgender, demigender, and non-binary. Demiflux people may one day feel strongly non-binary or strongly cisgender. They do not need to flux between all 3 and may flux just between demi and cis, or any other conbonation.
Demifluid: Demifluid people's genders are very similar to demiflux people, but their gender tens to change more rapidly or frequently than demiflux people.

DISCLAIMER: These are NOT all the types of demigenders out there!
