Open House: The Great Sex Experiment

Claude and Amy head to the red room with resident Georgie, hoping to find the right blend between instant sexual gratification and deep emotional connections. Alex and Alana, a young couple with two young children, describe themselves as 'sexual adventurers' and want to open up with like-minded others. However, Alana has a jealous streak, which she knows she must overcome.

Engaged couple Tom and Lauren have been trying to open up their relationship, but stage fright has meant that Tom has struggled to rise to the occasion. If he cannot perform, might it signpost the end of their relationship? Alex's confidence is rattled after watching partner Alana have wild sex with resident Georgie. He still hopes to bounce back from this setback to fulfil their dream of a full couple swap.

Chris and Simon, the retreat's first gay couple, are engaged to be married. Neither of them have ever had sex with a woman before, but as they approach their big day Simon wants to explore whether or not he might be bisexual and work out what that means for his identity and their relationship. Meanwhile, Tom has erectile concerns and is wondering whether participation in an orgy might help. He and his fiancée Lauren consider whether to have sex away from each other in separate rooms with resident couple Gage and Olivia.
