In my opinion these work for both polyamorous and polygamous relationships.
In our relationship ( the triad) we hadn’t yet set rules, because at the beginning we decided sex was out. then recently our partner went away and the opportunity arose. There was a bit of tension unbeknownst to her bc our bf gave consent but was still upset and doesn’t want to tell her since we hadn’t discussed it as a triad and he feels he has no right. So now we are going to an agreement at some point soon and decide where we all stand again.
FYI this should have been done a while ago and though I suggested it a few times it never happened. I wont make that mistake twice and neither should you.
I think I’ll update this post as I find more article on this subject
