The Sex Inspectors, a series in which couples will be filmed having sex, with their performance assessed by experts, will be screened in the autumn. The series will be modelled on The Dinner Party Inspectors, in which experts on etiquette gave critical feedback after observing the interactions of diners. The production company Talkback, which is behind both shows, has begun recruiting couples to tackle problems including differences in sex drive and difficulties created by having children.
