Well I already mentioned the ones in Discord, so you can add those.
I don't remember if you had hermaphrodite in your last one. You could add that one or if you're meme inclined (and I know you are) you could just have a choice that says "IT'S MA'AM!" and "MOTHERFUCKER, STEP OUTSIDE AND I'LL SHOW YOU A FUCKING SIR!"
For the "Ichel's Day of Love" substory in my Book of Vanishing Tales game, there was a null-gender panda lamp and a sentient blob creature made from a bucket of various bodily fluids. Also a dragon-man, but that was inspired by Trogdor the Burninator and so not very unique.
please add Muslim I cant remember the last time I've been able to play as my dad. Lame
