The BBC has put a challenge with a difference to 12 teenagers: go five months without having sex.
A new reality show will follow six boys and six girls aged 15 to 17 as they swap their sex lives for the kind of celibate, 'no sex before marriage' lifestyle practiced by the likes of Jessica Simpson.
The youngest of the dozen teens, Wesley, lost his virginity aged only 12.
It's all very different to the world inhabited by Jess and fellow celeb Katie Holmes.
"I promised God, my father and my future husband that I would remain a virgin until I got married. I just always knew it was something I wanted to do," Jess said. She married singer Nick Lachey after three years together.
Katie Holmes, engaged to actor Tom Cruise, has said she too plans to wait until her wedding day, saying she's "boring, boring, boring. If you want dirt, I'm not your girl."
No Sex Please, We're Teenagers starts on BBC Two next month and ends with the dozen teens sharing a house together to see if they resist each other.
The series was thought up by two Christian youth workers, Rachel Gardner and Dan Burke.
The cameras follow them as they set up a Romance Academy to teach old-fashioned dating.
Only three of the 12 are virgins, including Mounisha, a 16-year-old Hindu girl who "wants to meet the right person".
It comes after shock at two contestants on Teen Big Brother having sex while in the house in 2003.
But a BBC spokeswoman said: "This is not a reality show in the Big Brother sense, it is a three-part observational documentary series covering a period of five months."
