Made in Chelsea

This is a structured-reality show on E4. It's about a large group of rich, privately-educated young adults who live in West London.

They love having a large number of short-term relationships and are very keen on cheating during those relationships by having casual sex with other people. They also enjoy a lot of casual sex whilst single. Why then, do we never see them in bed with each other - let alone having sex? Hearing the participants talk about their sex lives is the highlight of show - so why don't we ever see any of them passionately kiss - let alone have sex?
