I had a brief look at the Science Daily piece, and I can see how how any sort of coercion and overt domination is a maladaptive strategy. While I certainly support the right of couples to stay monogamous out of choice, I don't believe that our culture actually offers choice. Monogamy is the default and if you stumble across anything else it is remarkable and something that you have to fight for and defend. My husband and I were happily monogamous for over 20 years and then we consensually decided to open up our relationship. It was a bit bumpy for a while, confronting the shifts in relationship styles, but eventually we got to a place that makes us both very happy. We've found something that is more natural for us and that strengthens our relationship while allowing us greater freedom. Perhaps it isn't for everyone, but I do think there is something to be said for normalizeing consensual non-monagamy as a viable possibility.
