Channel 4 is to interview couples immediately after they have had sex on a TV show, it has announced.
The couples will be quizzed by Mariella Frostrup and a panel of experts moments after they emerge from a soundproofed box in the middle of the studio.
Channel 4 said no intercourse or nudity would be seen in the pre-recorded show.
The show is part of a new “real sex” season, which will also include a documentary examining the effect of pornography on British teenagers.
Sex Box, said Channel 4 commissioning editor David Glover, is “a rather mischievous, fun idea that actually allows sex to be completely private but the conversation to be truthful and immediate”.
