The Bride Wars star who has dated actors Owen Wilson and Dax Shepard and cyclist Lance Armstrong since divorcing Black Crowes rocker Chris Robinson in 2006 admits her mother Goldie Hawn was concerned about her interest in the opposite sex from an early age.
Kate, who is single for the first time in years, said: "When I was a teenager, like, when I turned 16, I loved boys. That was just my thing. My mom was like, 'Oh boy, she loves boys!'
"I always loved boys. I still love boys. First of all, I always had a boyfriend. This is the first time I've been single since I was 16!"
The 29-year-old blonde beauty who has a four-year-old son Ryder with Chris - insists the key to making a relationship work is having a healthy sex life.
She added to Americas Elle magazine: "People think you can put your sexual life on hold, but you have to find time for it. Without that relationship, our family is broken. My mom really implanted that in me when I was pregnant."
Despite her success with men, Kate confessed she has been on some bad dates in the past and is often insulted by her friends ideas of a good love match for her.
She explained: I went on one where I just left because he was so boring.
