The Observer | Review | 'I'm trying to wean myself off younger men': "The series goes out at 11pm. And the footage is extraordinarily frank, even with clever cropping and pixellation. Couples draw their bodies on a blackboard and identify the bits they like stimulated. Then there's the jaw-dropping moment where one of the men admits he ejaculated so fast after a spot of spanking he temporarily blinded his partner. It sounds terrifying - and just occasionally it is - but actually the shows are redeemed by the good humour and bravery of the participants."
