When one is a practicing sex educator and clinical sexologist with several degrees to her credit, it’s only a matter of time before a book deal or movie option comes around. Now a major motion picture nominated for an Oscar, The Sessions is a story of one of Cheryl Greene’s patients who was confined to an iron lung after contracting polio at age six. The devoutly religious man wanted to know what it’s like to “be” with a woman, in the Biblical sense; Greene served as his sex surrogate and, lo and behold, it changed his life and inspired a Hollywood script. Greene speaks about her new book, An Intimate Life: Sex, Love and My Journey as a Sex Surrogate Partner, on Friday, Feb. 1, at Book Passage. 51 Tamal Vista Blvd., Corte Madera. 7pm. Free. 415.927.0960.
