Nicole Kidman experiments with "strange sexual fetish stuff"
The `Nine` actress - who divorced Tom Cruise in 2001 following a 10-year union and is now married to country singer Keith Urban - says she has enjoyed exploring with the different aspects of love, sex and relationships over the years.
She explained: "My life has been about exploring types of love. I`ve explored obsession, I`ve explored strange sexualfetish stuff, I`ve explored the mundane aspect of marriage and monogamy. But Im still on that journey."
Despite the fascination people have with her love life, the 42-year-old beauty has vowed to take the details of her past relationship with Tom to her grave.
She told Britain`s GQ magazine: "I have never discussed the intricacies of it and I never will.
"I burned most of my journals after I remarried. You`re only going to find out bad things. You can`t read somebody`s diary. You shouldn`t read it.
"I know I live inside some rose-coloured cloud but I`ll never waver on it. I am not writing a book. I will go to the grave with all my secrets, all my stories."
While together, Tom and Nicole adopted children Isabella, now 17, and Connor, now 14. Nicole also has 15-month-old daughter Sunday Rose with Keith and Tom is father to Suri, three, his daughter with wife Katie Holmes.
