Movie goddess Marilyn Monroe cried tears of joy after her first orgasm and credits her psychiatrist DR RALPH GREENSON with releasing her pent-up sexual tension.

The SOME LIKE IT HOT star revealed her special thanks to the doctor during one of their tape-recorded sessions, which have been made public following Greenson's death.

Monroe had struggled to relax during sex until she began counselling with the psychiatrist, but his advice helped her achieve powerful multiple-orgasms.

She said, "Bless you doctor. What you say is gospel to me. By now I've had lots of orgasms. Not only one but two and three with a man who takes his time.

"I never cried so hard as I did afterwards. It was because of all the years I had never had one. What wasted years. How can I describe to you, a man, what it feels like to a woman? I'll try.

"Think of a light switch with a rheostat control (dimmer). As you begin to turn it on, the bulb begins to get bright, then brighter, and brighter and finally in a blinding flash is fully lit.

"It is so good... Doctor, I worship you."
