Do you remember if "good girl" happens during specific scenes or actions? There's a lot of mentions of it in the code, and most of them seem to refer to NPCs correctly. I do see some mentions of "good girl" during breastfeeding scenes, which makes sense, but you're right that it's not very inclusive. I also see it used with some male chastity-related scenes, which is a whole other can of worms.
I'm all for more non-binary representation. We've got a lot of "herms", but they're all women. It'd be cool to just casually have some non-binary or gender-non-conforming characters, especially beyond just having salmacian bodies.
