Marilyn Monroe has undoubtedly been the ultimate sex symbol for the past 60 years, but in a new book written by Tony Jerris, "Marilyn Monroe: My Little Secret," Jane Lawrence told the author about her sexually explicit encounters with the 1950s goddess.

Aside from hooking up with Lawrence, who was 16 at the time -- 14 years younger than Monroe -- the blonde bombshell allegedly had encounters with Hollywood actresses Joan Crawford, Marlene Dietrich, Barbara Stanwyck, and Elizabeth Taylor, RadarOnline.com reported.

Lawrence explained that she met Monroe when she was only 12, and the two formed a lifelong friendship after they were able to bond over being adopted from the same orphanage.

"Jane met Marilyn when she was 12 because her adopted father ran the legal department at RKO studio," the author of "Marilyn Monroe: My Little Secret" told RadarOnline.com. "They soon became close friends after realizing that they had been in the same orphanage at different times of their lives, even though Marilyn was 14 years older, and neither of them knew their birth fathers. They became close friends because there were so many similarities in their past."

Jerris added: "Jane always struggled with her sexuality, she talked to Marilyn about this many times and she was very understanding. She told her, 'Whatever your sexual preference is, it means nothing -- love is love.'"

The author and Lawrence met in 2001, and they became close friends and business partners, RadarOnline.com said.

On the night of their first sexual encounter, Monroe asked Lawrence to come to her home to help line some shelves, Lawrence told Jerris in the memoir. Lawrence also launched Marilyn Monroe's fan club, the Daily Mail said.

"The champagne makes me happy. The pill makes me happier faster," Marilyn told her when Lawrence arrived, referring to the prescription drug Nembutal, whose generic name is pentobarbital, according to PubMed Health.

Although they did attempt to line the shelves, Monroe leaned over and planted a kiss on Lawrence's thigh with a "mischievous twinkle in her eye," Jerris wrote.

"The next few minutes became hazy, surreal and dream-like. My pulse leaped as Marilyn kissed my thigh again. ... [S]he then leaned in and kissed me full on the lips, very softly and very slowly. I was nearly hyperventilating," Lawrence recalled in the memoir.

"We moved through the living room into the bedroom," she explained how the passion escalated. "Marilyn used her tongue, lavishly flicking and licking, an entirely new sensation for me. ... With the girls I had enjoyed sex with, there was often a shyness and hesitancy, not the hunger and confidence Marilyn displayed."

The two spent the night together, and Lawrence realized that she was gay. However, Jerris does not believe Monroe was a lesbian, he told RadarOnline.com.

"The experience confirmed to Jane that she [herself] was gay, and as she got older she has relationships with other girls," but Monroe "was just a free spirit. She was a very open person."

The two stayed friends until Monroe's untimely death on Aug. 5, 1962, according to the book.
