I don't know how the show managed to get on the air. It's a UK show. A "contestant" chooses someone to go on a date with based on their looks. There are 6 or 7 people (I've only seen a couple of episodes, so I'm not entirely sure) totally naked behind a door, which reveals each person from the bottom up. So yes, the host and contestant discuss the relative merits of what they're seeing as the door stops midway and then just below the head. The sex of the people behind the doors depends on the preference of the contestant. Usually, half the show is a woman choosing a man and the other half is a man choosing a woman. But there have been women choosing women, men choosing men, and a contestant having people of both sexes to choose from.
The idea of choosing a date based on their genitalia seems extraordinarily bizarre to me. On the positive side, I personally think that destigmatizing the human body is a good thing. If more people knew what other regular, normal people look like, there would be fewer body image issues. Well, in my opinion. Or not. I only have an opinion. No facts at all . . .
As far as entertainment goes, in my opinion, your life may be sheltered, but you're not missing much.
