Couples are to have sex in a soundproof booth and then immediately be quizzed about their session by Mariella Frostrup in front of a studio audience for a new Channel 4 show.
The station said no intercourse or nudity will be seen in the 'Sex Box' programme but the “immediacy” will encourage a more open and honest discussion about their experiences.
The hour-long programme, to be screened next month, is part of the broadcaster’s Campaign For Real Sex season, which will look at the effect of pornography on the love lives of ordinary people around the UK.
