London: Actor Ashton Kutcher says he pees with his dogs in the back garden every morning.

Kutcher, who is married to the much older Demi Moore, said: "I pee with the dogs. They're marking their territory and I'm marking mine."

He claims he does that to maintain his masculinity. "Demi's not happy about it but I've 13 women in my house sometimes - my wife, housekeepers, cook, nanny, my assistant and three daughters. Everyone in my life is a woman - so I have to mark my territory," Kutcher said.
