AT 56, former “Sex and the City” bombshell KIM CATTRALL says she’s embracing everything age is bringing her way – especially the sex!

“There is no need to feel defeated at 40, 50 or 60,” Cattrall proclaimed in an interview. “I’m having the greatest time in the second half of my life – and have enjoyed the best sex after the age of 40.”

While she’s played the blonde sexpot on camera, Cattrall – a Golden Globe winner for her role as bed-hopping public relations exec Samantha Jones on “SATC” – claims her real-life sex life was far from fabulous.

“I lost my virginity at 15 and thought, ‘Is that it?’ I was not ready for the experience,” she confessed. “It set a pattern. I was not expecting a great deal from sex – and I did not get it either.

“I remember going to bed with a real good-looking ladies’ man in the hope that he would teach me what I had been missing. He didn’t.”

The British-born beauty, who’s been divorced three times, is now performing on stage in London. She’s been dating renowned wealthy American artist Clifford Ross, 60, and says she has the utmost respect for actresses of a certain age.

“Whenever I take a look at women like Helen Mirren or Judi Dench, in their 60s and 70s, I think, ‘That’s how I want to be,’” she noted.

“I like the thought that I’ve saved my best years for last.”
