' elusive mystery of mysteries, that is familiarly known as chemistry. What could be more fun than the cringe fest of two people trying to be on their best behaviour while trying to impress someone else, with a sizeable TV audience watching their every move? In this state of vulnerability - and it's the gentlest sense of the word - the direct and often taboo first-date questions, tend to elicit candid and honest responses.
All the way from Blind Date through to First Dates, we have been there watching through our fingers at the awkward moments as well as feeling relieved that it's not us up there on the screen. The matched couples are of a variety of dating experience, age, sexual orientation and body size.

The US version of the programme - Dating Naked - which blurs out all sensitive parts of the body has proved so popular that it has been commissioned for a second season.

Television audiences in France can expect a cheeky surprise in the coming weeks, when a new reality programme featuring contestants dating in the nude, hits the screens.
One of the couples that met on the show even ended up getting married.
Reality TV shows have proved remarkably popular in France with shows like "The Angels of Reality TV" pulling in millions of viewers, partly thanks to stars such as Nabilla, who has billed herself as France's answer to Kim Kardashian and gone on to make a career for herself, before being charged with attempting to kill her boyfriend.
