After the hypocrisy and tyranny directed at female sexuality in the 19th Century the change of attitude occurred slowly. Literature became more permissive with authors like D. H. Laurence, Henry Miller and Anais Nin being influential. Theatre and cinema remain conservative. In the real world Marie Stopes’Married Love was greatly influential, listed by Bragg as one of “the 12 books that changed the world”, stressed the emotional importance of sexual intercourse within marriage. She did not discuss contraception, masturbation or sex outside of marriage in the earlier editions. Kinsey and colleagues in 1953 broke the scientific silence by publishing details of the sexual behaviour in the human female. Seymour Fisher devoted a whole book to the female orgasm and Shere Hite in her extensive use of questionnaires from women described six basic types of masturbation in women. Masters and Johnson's work on the physiology was a landmark in understanding normal sexual response. Greenblatt pioneered the use of testosterone for loss of libido and subsequently the female androgen deficiency syndrome (FADS) has been recognised. There are now good control studies indicating the value of testosterone implants, tablets and patches by Davis and her colleagues to improve the problems of hypoactive sexual desire disorder (HSDD).
