It was "Polyamory: The Next Sexual Revolution?"
It was very tasteful and highlights a triad that has developed into a... Quint? (5 people with the triad as the foundation.) It made me realize right away that these relationships are all about putting others first, and how, when you do that, your own needs are inherently met because everyone is less selfish.
And thank you for the "welcomes" everyone. It's encouraging to see quick responses when embarking on such a new and strange journey.
