Ah, ok, actually read the article. They have a strict primary/secondary hierarchy that is not open to the possibility of another partner every becoming co-primary, and the female partner is only allowed to have piv intercourse with her male primary partner. I'm glad it works for them, though it wouldn't for me.
I do appreciate that if one of them wants to veto a long-standing lover argument is allowed and consensus must be reached.
But goddamn I resent the wording in the first sentence of the bit you quoted above, as it clearly implies that a secondary partner, who does not get veto power, is not participating in "real love."
Fuck. That. Shit.
