A resident swinging couple on Channel 4's 'Open House' said they originally applied "after a heavy night out" - and '10 times more' sex happens off-camera.
Lily Jones, 33, and her partner, Joe Turner, 30, feature in Channel 4's 'Open House: The Great Sex Experiment'.
The show, which is currently airing, sees previously monogamous couples explore open relationships and sex with others.
Engaged Lily and Joe are part of the group of 'residents' - who are experienced in non-monogamous activities and help introduce it to newcomers on the show.
Lily, an account manager, and Joe, a tradie, began swinging two years ago and applied for the show after a night out.
But they jumped at the opportunity when producers responded and revealed it's even more steamy in real life.
