Can you show me your nonbinary sims/couples/families, and give a little of their backstory?

Sure thing! My main is Jamie - he's not quite a Simself, but he's pretty close. Slightly different identities (he's genderfluid, leans more towards masc, and uses he/him pronouns as well as they/them, I'm agender and only use they/them; he's pan and I'm aro-ace), but otherwise, pretty similar. He's currently a spellcaster and is the Sim I basically do everything with - gaining skills, going places, all sorts of stuff. Basically living his best life!

(Whoops, hastily had to blur out some of the writing on one of Jamie's outfits XD;; )

Gem Key is an alien, and I guess Sixam does genders sliiightly differently? Either way, she leans towards femininity as the closest to how she would define her own gender, so she describes herself as a demigirl who likes girls. She's an artist currently living with her girlfriends Aisling (a deer girl) and Sienna (a plant fairy), and Aisling's half-sister Ana (a spellcaster).

Lucc (pronounced 'Luck') Madden is a genderqueer musician originally from Sulani, growing up on the grounds of their parents' resort. They now live in San Myshuno with the intention of making it as a musician, producing bright, beach-themed indie (and some radio-friendly pop). Pronouns are they/them or ey/em (Elverson spivak).

Couple of Gallery Sims - Rylie Lancaster was made for Pride and is based around the nonbinary flag, and is a cheery, outdoorsy animal lover. Luca LaBelle is a flirty, creative klepto and is lowkey based around the demiboy flag (as in I was five outfits into my blue/silver/white colour scheme and went "oh hey!").

And, nonbinary premade makeovers! Morgyn, of course ❤️ (genderfluid), Izzy Fabulous (just uses 'queer' as their main identifier, both for gender and orientation), Darling Walsh (genderflux between agender and demiboy), and Hugo Villareal (not 100% sure, they're only 15 and are still working things out, they just know 'not a boy').

Update to two of the above, I guess! YA versions of Darling (transmasculine, now on T, he/him pronouns) and Hugo (agender, presents fem, any pronoun but preference for they/them).

I have one sim who I imagine to be non-binary, agender to be precise, and I kinda modeled her after myself, but only to an extent (I actually look completely different, but in terms of gender identity we're basically identical). She also has the same pronouns as me, either she/her or they/them.

As you can see, she doesn't look androgynous as many other enbies do, partly because I took inspiration from myself (if you look at me, you would know my birth sex immediately without a doubt) and because I want to show that non-binary people can look any way they want and don't have to look androgynous for their identity to be valid.
