chrishasaflavor asked: Have you ever been in an open relationship?
No. I honestly haven’t been in very many relationships, for reasons that should be obvious to long-time readers.
Pretty sure I’d be okay with some forms of contemporaneous relationships, but nothing complicated like formalized polyamority as I have enough trouble dealing with social interactions without so many multilateral ground rules. However, for any kind of economic arrangement (e.g. cohabitation) I think monogamy would be optimal as it creates higher barriers to exiting the relationship (and leaving such relationships tends to be relatively costly).
