So one of my on-and-off hobbies is collecting xenogenders, as well as xenopronouns. This is a list of most of the ones I've collected! Note: Not everything here could be considered a gender, especially once you get into the age regression stuffs. Really this is more of a flag collection than anything, but gender collection makes more sense.
