Does anyone remember
The Last Psychiatrist? He wrote a book I cannot remember the name of sadly. Every time Melina or Destiny talk about their open relationship I'm reminded of one of his main points.
One of the author's main assertions is that cuckholds think/claim they get off from powerlessness and deprivation but it's really the opposite. The Cuckhold is at an even deeper level, getting off on depriving their partner of physical/emotional/spiritual intimacy.
Destiny's open relationship is that dynamic but instead of being hidden under layers of self debasement like a "traditional" cuckhold it follow's Destiny's MO of "mask off liberalism."
What's the excuse? Something along the lines of "how can I deny my SO sex with other people? I don't own her." That's really an excuse to go fuck random hoes off e-clout and she can't complain about it because the parameters are set.
When you choose someone to marry you're giving them a metaphorical piece of yourself. Call it ownership, call it safekeeping, but if you love someone you have relinquished some part of yourself to them.
Imagine everything you give to the person you love as a rubber band ball of emotions and dreams and loyalties, the "ethical nonmonogamy" people attempt to sepparate physical sensuality from emotions, possesion, ect. Like pulling a strip off the rubber band ball.
At best, it's one or both people massaging their own ego by trying to force the belief that relationships shouldn't have that element of "ownership" because "we're enlightened and past that."
At worst it's one partner sadistically getting off on not allowing the other person in or spitting back part of what the other person has given them.
