Hollywood superstar Nicole Kidman is usually tight lipped about her personal life but the actress opened in an interview, saying that her experiences of love range from "mundane" to "strange sexual fetish stuff".

The 42-year-old actress, currently married to country singer Keith Urban opened about her experiences in an interview to GQ magazine, reported Daily Mail online.

"I've explored obsession. I've explored loss and love, I've explored strange sexual fetish stuff. I've explored the mundane aspect of marriage and monogamy," she said.

The 'Moulin Rouge' actress who posed in black underwear and thigh-high boots for the magazine's cover, described her present marriage as "raw" and "dangerous".

"You work on it. It's a very extraordinary, adventurous place to be, incredibly raw, incredibly dangerous and you're very much out at sea. You're exposed. You could drown. When you commit to someone like that, you live and die together by that decision," said the actress.

She has remained tight-lipped about her 10 year marriage to actor Tom Cruise and vows to keep her secrets.

"I became famous very young. I became very famous because I was the wife of somebody. I want to honour that marriage for what it was, and there is nothing I would go into about that. I have never discussed the intricacies of it and I never will," the actress said.

Kidman, who has a 1-year-old daughter Sunday Rose with Urban, will next be seen in the star studded musical 'Nine'.
