Robert F. Kennedy Jr kept a secret diary which reveals his battles with his self confessed biggest defect – his ‘lust demons’.

The New York Post says he also kept a scorecard of more than two dozen conquests, according to the diary which was found in their home by his wife Mary Richardson Kennedy.

The paper claims that, distraught over their impending divorce and Kennedy’s serial philandering, she committed suicide last year.

The report states that a copy of the 398 pages, reviewed by The Post, details RFK Jr.’s daily activities, speeches, political activism and the lives of his six children in the year 2001.

The diary also records the names of women — with numbers from 1 to 10 next to each entry. The Posy says that Mary told a confidant that the codes corresponded to sexual acts, with 10 meaning intercourse. There are 37 women named in the ledger, 16 of whom get 10s.

It details Nov. 13, 2001, when RFK Jr. recorded a triple play. The report notes: “The separate encounters - coded 10, 3 and 2 - occur the same day he attended a black-tie fund-raiser at the Waldorf-Astoria for Christopher Reeve’s charity, where he sat next to the paralyzed Superman star, magician David Blaine and comic Richard Belzer.

“It was a hectic month for Kennedy, who traveled to Toronto, Louisiana and Washington, DC and listed at least one woman’s name on 22 different dates, including 13 consecutive days.”

The Post says most women are identified only by first name in the ledger and include a lawyer, an environmental activist, a doctor and at least one woman married to a famous actor.

A Post reporter questioned Kennedy about the diary and was first met with six seconds of stunned silence.

He then said: “I don’t think there is any way you could have a diary or journal of mine from 2001 I don’t have any comment on it. I have no diary from 2001.”

The Post also says the diary is laced with Kennedy’s Catholic guilt over his infidelities, which follow the same pattern of affairs pursued by his uncles, John F. Kennedy and Ted Kennedy, as well as his own father.

The paper says: “On days without a woman’s name, Kennedy would often write ‘victory’. This meant he’d triumphantly resisted sexual temptation, according to a source close to Richardson.

“Despite the terrible things happening in the world, my life is . . . great,” he wrote on Nov. 5, 2001.

So I’ve been looking for ways to screw it up. I’m like Adam and live in Eden, and I can have everything but the fruit. But the fruit is all I want.”

The paper notes that the 59-year-old son of the assassinated US senator was so tortured by his desire that spending a month in jail in Puerto Rico was a welcome respite.

“I’m so content here,” he writes during his July 2001 incarceration for taking part in protests of the US Navy’s bombing exercises in Vieques. “I have to say it. There’s no women. I’m happy!

verybody here seems happy. It’s not ­misogyny. It’s the opposite! I love them too much.”

Yet Kennedy adds, “I love my wife and I tell it to her every day, and I never tire of it and write her tender letters.”

In summer 2001, Kennedy wrote that “I have been given everything that I coveted — a beautiful wife and kids and loving family, wealth, education, good health and a job I love yet always on the lookout for something I can’t have. I want it all,” he writes. “No matter how much I have — I want more.”

Kennedy and his wife separated nine years later when he filed for divorce. In May of 2012, Richardson, 52, committed suicide by hanging herself in an outbuilding on the couple’s Bedford estate.
