Yeah. Like I’m very poly and my wife and I don’t have vetos or anything but if she started dating my sister I don’t know who I’d yell at first.

And with identical twins it’s somehow grosser. Like fraternal twins already need effort in parenting to ensure they’re not at risk of codependency with each other, and with identical twins there’s this cultural force of treating them like they’re interchangeable. It’s really fucked up.
