Sex in the studio for new Channel 4 programme

Couples will have sex in a TV studio and then be interviewed about their experiences as part of a Channel 4 programme.

The pre-recorded show, Sex Box, hopes to learn more about the love lives of Britons and is part of a new season that aims to “reclaim sex from pornography”.

Three couples were invited to have sex in a soundproofed, opaque cube before being interviewed over their love lives by agony aunt Mariella Frostrup and a panel of experts. The couples include a pair of twentysomethings, two long-term lovers and some childhood sweethearts.

Frostrup said she hoped to spark a “mature, intelligent discussion” about sex. Channel 4’s head of factual programming, Ralph Lee, added: “It’s quite a chaste programme — there’s no sex in it.”

Sex Box will be broadcast at 10pm on 7 October.
