Looked after by non-monogamy coach Effy Blue, the group are encouraged to have sexual encounters with each other in order to test their relationship boundaries.
On Friday’s episode, Exeter-based teenage sweethearts Lauren and Tom were the newest additions to the group, wanting to feel more confident in having an open relationship.
After getting engaged three months ago, it was Tom who was struggling most with the idea, admitting he has found himself struggling to perform in a multiple-person sexual scenario.
He’s also suffering from self-esteem issues after being diagnosed with Sudden Death Syndrome, a heart condition that has meant he can no longer go to the gym, putting on weight as a result.
The bisexual bride-to-be admitted to Effy that she didn’t “feel complete” with either men or women, and had a hard time accepting being with just one person for the rest of her life.
Setting up a barn dance mixer, the couple were told to invite others into their room for foreplay, with Tom taking the lead in a situation that doesn’t necessarily lead to sex or his need to perform.
However, when three couples say yes, Tom admits he “felt petrified and sick” as he’s tied and blindfolded to a bed.
With Lauren watching on excitedly from the sidelines with a glass of wine, Tom lets the women take control as they start caressing, kissing and touching him.
One purred to him: “You’re getting worshipped, you’re getting all the attention.”
Sharing his fears, Tom said: “I definitely want to make Lauren happy, I will try anything. To jump this hurdle this early, in my head, I can’t perform. I just freeze.
“Once I’m in that rut, I can’t get out of the rut.”
As the episode came to an end, it seems the events of the night take a toll on Tom, who is heard vomiting in the bathroom.
However, with Lauren insistent on wanting to make the open relationship work, will they be able to survive the retreat?
Open House: The Great Sex Experiment airs on Channel 4.
