What's it like to watch your partner have sex with another person? What about a group of people? Welcome to the world of swingers, where couples "play" with each other and with the boundaries of sexual expression. Join Yumi Stynes at a sex club as she pulls back the orgy room curtain and meets women who swing to find out why they love 'The Lifestyle' and how it's transformed their relationships. With special thanks to Juliet Richters, Honorary Professor of the Sexual Health Program at the Kirby Institute. Thanks also to Jess Cattelly from Our Secret Spot.
