No Sex Please, We're Teenagers (2005)

The dozen 15- to 17-year-old participants-who include a 15-year-old who lost his virginity at 12 and more than one virgin-abstained for five months, and then "spent a weekend sharing a house with two rules - girls and boys were not allowed in each other's bedrooms and no alcohol." They'll also attend "Romance Academy" with "two Christian youth workers."
