Can open eroticism between more than two consenting adults be considered natural sexual behaviour? Gould is an investigative journalist who took a deep dive into the history and world of swingers. He interviews participants, pioneers, academics and a host of experts and, in the tradition of immersive journalism, he becomes subject himself. He explores some interesting and surprising concepts, including the idea that swinging, in stable marital relationships, reinforces the emotional and erotic bonds between couples. Imagine that!
