Sexual Intercourse began in I963, according to Philip Larkin's 'Annus Mirabilis'. But what of the dark ages before the sexual revolution? A new study shows them to be not quite as repressed, unfulfilled and pitiable as many have been keen to cast them. In this edition Laurie talks to Kate Fisher and Simon Szreter about their illuminating exploration of intimate life in England between 1918 and 1963, which involved them speaking frankly and in depth to almost a hundred people about their sex lives in the period.
