The 60-year-old `Dancing with the Stars` contestant boasted of her marathon romps, but warned they ultimately couldn`t bring happiness to her relationships.

Speaking on `The Ellen DeGeneres Show` Kirstie said: "I really hadn`t had a boyfriend for the last ten years - a serious boyfriend. It was the best ten years of my life. I had a lot of freedom.
"The way I used to pick guys was so shallow. Hot? OK, that`ll be my husband.

"Here`s my big revelation. I decided that in the best of times you have two hours of sex a day, so you have 22 hours left."

At this point show host Ellen stopped the former `Cheers` actress to clarify her statement, saying: "Whoa, whoa, what? Two hours a day?"

Kirstie - who has been married twice, to high school sweetheart Bob Alley and actor Parker Stevenson - jokingly replied: "Not enough?"

She later clarified her estimated time spent lovemaking, saying: "There`s the prelude, the sex and there`s the winding down."
