The former supermodel says she and her husband Rande Gerber set aside time each week to make love because their lives are so busy with work and their two children - son Presley, 11, and daughter Kaia, nine.
The brunette beauty oversee a small empire of businesses, from skincare to home furnishings, while Rande is responsible for several nightclubs including Sky Bar and the Whiskey Bar in Los Angeles.
While speaking about the couple`s once-a-week date nights and commitment to their sex life, she said: "If you just wait for the moment to strike, you`re going to have some dry spells. But even if you don`t start out in the mood, once you get it going, everyone`s on board."
Although sex is very important to Cindy, she insists she works hard at all aspects of her relationship and is prepared to talk about anything that`s on her mind, in contrary to her husband.
The 44-year-old star added to Ladies Home Journal magazine: "When something`s wrong, I`m all about talking things out. Rande`s philosophy is, if everything`s good, why talk about it, and if it`s bad, why talk about it? He sometimes says, `Relationships aren`t supposed to be this hard.` And I`ll say, `Who says?` It`s so easy to want things to be happy all the time, but happiness shouldn`t be the goal. It`s OK not to feel happy all the time."
