Once you’ve seen Channel 4’s Naked Attraction, you can’t unsee it. A contestant is presented with six boxes containing six naked people. The boxes lift from the ground up, in stages. First come the goolies; second the torso; third the face. Our hero then chooses one of these bodies to go on a date with. This, we are told, injects some honesty into modern relationships. The real revelation, however, is just how ridiculous human beings look naked, that devoid of mood music and soft lighting, we’re all about as sexy as a butcher’s shop window.
