Marilyn Monroe, the world's number one sex symbol and the most desirable woman on the planet, was not the man-eating siren that her image suggested, it has been revealed. Fifty years after her death, an author who met the star has questioned her sexual identity. Although she married and divorced three times, she was though few people are aware of the fact - a lesbian by inclination. She admitted to sexual encounters with actresses Joan Crawford, Barbara Stanwyck, Marlene Dietrich and Elizabeth Taylor, as well as with both her acting coaches, Natasha Lytess and Paula Strasberg. Only a day before Jean Negulesco, who directed her in 'How To Marry A Millionaire', was due to visit her, Monroe was found dead. "I still think I might have saved her if I could have got to her in time," the Daily Mail quoted him as saying. "You know what was wrong with her, don't you? "Her whole existence was a search for identity, and her sexual identity was a complete lie. "She told me once she had never had an orgasm with a man in her entire life," he said. And yet Negulesco's assertion is validated by the taped transcripts of Marilyn's sessions of psychoanalysis with her psychiatrist, Dr Ralph Greenson, at the end of her life. "What I told you is true when I first became your patient," she says in the transcripts. "I had never had an orgasm. I well remember you said an orgasm happens in the mind, not the genitals. "When I did exactly what you told me to do, I would have an orgasm? what a difference a word makes. "You said I would, not I could. Bless you, doctor. What you say is gospel to me," she said. Another of those who worked with Monroe, actress Celeste Holm, who appeared with her in 'All About Eve', and who died last Sunday, said that Marilyn's sexual problems were rooted in her traumatic childhood.
