The former X Factor judge said that the intimacy between herself and rocker Ozzy “remains the best thing in the world.”
She has opened up on how crazed Ozzy, 71, was “way over sexed” during his 20s thanks to groupies and rock’n’roll excess.
However he still is a stallion to wife Sharon, rocking and rolling in bed at least twice a week.
When asked “how many times are you getting it” by a co-host on TV, Sharon replied: “It is getting less. It used to be three times a day.
“Now it is much less now, let’s say a couple of times a week, which is normal in a long, long relationship.”
Sharon called out Oz for his raucous past.
“Let me tell you something Ozzy was way over sexed. That is no secret. He had enough for all,” she said.
She chuckled: “We like to share our business, no problem.”
Her comments came on US TV as she spoke on a new study which revealed the importance of women having sex in their “golden years.”
Sharon insisted that passion had remained a vital part of her life even after almost 40 years of marriage.
She said: “Sticking up for the older ladies here. When you are in a relationship, your relationship has highs and lows; and depending on where you are with your relationship you love each other more.
“It is not just about the sex, it is intimacy being with that person with love and they love you. It just changes.
“Those goosebumps that you got change to something else. It is a warmth, respect - it is a feeling of love and comfort.
“Those butterflies and things change to that comfort.”
She said of having sex in older age: “Why should it change because you are a certain age?
“The thing is if somebody moves you in a certain way, you love them you make love, it is the best thing in the world.”
Sharon spoke on the US version of Loose Women, The Talk.
Last month Ozzy admitted his long running infidelity to wife Sharon was an “occupational hazard”.
In an A and E Channel documentary where cameras filmed the pair, sat alongside one another on a sofa, he address his wayward behaviour.
Sharon blew up at Ozzy when he insisted: “I wasn’t a great cheater anyway”, hitting back, she said: “You were a f***ing great cheater. you ****.
“You fed all our friends, all the f***ing staff, then you came to me and f***ed every groupie there was in the world.”
Ozzy then reacted: “Well that was part of the job. That was an occupational hazard.”
Ozzy laughed before walking away from the cameras.
