There are provocative experiments, sexual scandal and lots of action between the bed sheets in Channel 4's new raunchy and risqué US import Masters of Sex.
Starring Michael Sheen and Lizzy Caplan, the series follows William Masters and Virginia Johnson, two of the most important researchers in the field of human sexuality, as they ask ground-breaking questions about our behaviour in the bedroom which help spark the sexual revolution.
