Writer and activist Dan Savage has been an outspoken critic of American society's expectations of monogamy. He advocates for people to be open to other relationship models:
“I acknowledge the advantages of monogamy when it comes to sexual safety, infections, emotional safety, paternity assurances. But people in monogamous relationships have to be willing to meet me a quarter of the way and acknowledge the drawbacks of monogamy around boredom, despair, lack of variety, sexual death and being taken for granted.”
But others cite the old quote about democracy being a bad system of government—until it's compared with all the others. Yes, monogamy is difficult and challenging, but compared with other options—it offers stability and emotional intimacy like no other relationship model.
Much of the recent research supports the anti-monogamous arguments. Across the globe, an estimated 95 percent of mammalian species and 85 percent of human cultures are polygamous. Critics say monogamy actually evolved as a way to guarantee paternity and control women. The book "Sex at Dawn: The Prehistoric Origins of Modern Sexuality" challenged much of the conventional wisdom around the naturalness of monogamy:
Marriage in the West isn’t doing very well because it’s in direct confrontation with the evolved reality of our species.
