The Sex Inspectors gives couples experiencing common sexual difficulties practical advice to reignite the passion in their relationship. The show is presented by Tracey Cox and Michael Alvear, who observe the couples’ behaviour in and out of the bedroom before devising a tailor-made programme of tips, tasks and techniques to get them back on track.

Nick (31), a holiday resort entertainer and nursery manager Sarah (28) are like chalk and cheese. He’s a born extrovert while she’s reserved and shy. The couple love each other and have been together for 10 years but their contrasting personalities are starting to have a negative impact on their sex life, leaving Nick frustrated and Sarah afraid he’ll leave her for a more adventurous lover. The Sex Inspectors come up with a programme of tips and advice that includes a kissing master class. The tips seem to have an instant affect on the couple, particularly Sarah who surprises Nick, as well as herself by revealing a whole new side of her personality. But will it be enough to help this mismatched couple find common ground?
