Channel 4's raunchy sex series is returning with a new open relationships expert, a new luxury location and some new twists. Now the team behind Open House: The Great Sex Experiment are looking for people to take part in series 3. The series questions whether monogamy is an outdated concept in modern relationships, following previously monogamous couples as they experiment in open sexual relationships for the very first time with the cast of sexually liberated Open House residents.

The first series, which aired in 2022, remains Channel 4 ’s biggest new unscripted 10pm series launch since 2017 and during the last two series the show has seen a slew of couples explore bisexual fantasies, group sex and daring threesomes with all of the action taking place in front of the camera. Before heading to the bedroom, they are seen getting to know their potential additional sexual partners at a mixer event hosted by the show's sexperts. If the couples like what they see, they can invite whoever they like to join them inside to take part in some steamy action.

Producers are now looking for people to take part in the third series. They say: "If you are a curious couple who would love the opportunity to explore non-monogamy for the first time, get in touch. If you are a sexually liberated singleton or already in an open relationship, you can also be part of the show as one of the retreat’s residents.

Potential applicants looking to apply are encouraged to do so via the Channel 4 website.
