Solo polyamory, relationship anarchy, and hierarchical stuff I think need to be better represented.
I avoid a lot of stuff I consider to be hierarchical nonsense. Stuff like "I need permission from my other partner for stuff I do with you". Anything with "veto power" is right out.
Con sex is probably over represented? I don't know if that deserves a whole bubble on its own. Seems like a more specific instance of something else.
I know, huh! I'm sure there are other venn diagrams, memes, infographics that make understanding complex topics like open human relationships so much easier. As our consciousness changes, more information dense ways of communicating about our relationships will naturally come into use.
