Today, we’re sharing the first episode of a new BBC podcast, Swingers.

Swingers tells the story of Ruth - a woman who joined a Swinging website and ended up having degrading sex with strangers more than 100 times.

Ruth says that she never wanted to join the website - but did it to please her husband who had been slowly persuading her for more than a decade. She ended up having sex with strangers in lay-bys and filming it for her husband. She ended up pregnant by a stranger and giving oral sex to another man while bleeding from an abortion.

This is episode one in the six-part series. To hear the rest of Ruth’s story, you can listen and subscribe to Swingers on BBC Sounds. If you’re outside the UK, you can listen on BBC.com or wherever you get your podcasts.
