Part 4: Promiscuity, monogamy & infidelity. What is the secret to keeping your partner happy?

Part 2: From circumcision to the female ejaculation. We enquire into the metaphysical distinction between sex and intimacy, and the very real question of which is the most intimate - a kiss or a blowjob? From circumcision - good or bad? - to the female ejaculation, more thoughts on those things they don't teach you at school. 

Part 1: The preamble - masturbation nation. As hoards of people arrive in Brighton for the May bank holiday dirty weekend, our Deputy Prime Minister is found to be banging his secretary, and John Osborn's diaries make a case study of the paradoxical British state of sexual obsession and repression, we set off on a journey to discover what good sex really is.
