Jane Fonda is having the best sex of her life.

Jane, who had a knee replacement operation in June, says lovemaking gets better with age. The legendary actress, 71, reckons keeping active in the bedroom helps her maintain her youthful looks.

“I owe 30 percent to genes, 30 percent to good sex, 30 percent because of sports and healthy lifestyle with proper nutrition and for the remaining 10 percent – I have to thank my plastic surgeon,” she tells German newspaper Bild.

“I’m happier. The sex is better and I understand life better. I don’t want to be young again.”
