Baring all and posing in her “birthday suit” to celebrate turning 73 years old isn’t the only thing keeping Suzanne Somers feeling young.

In a new interview with the Daily Mail, the actress opens up about her sex life, revealing that she and husband Alan Hamel, 83, credit weekly shots of the melanocortin-based peptide PT-141 (also known as Bremelanotide or Vyleesi) with giving them a boost in the bedroom. According to Somers, the couple — who married in 1977 — make love twice a day thanks to the “sexual stimulant.”

“I usually say I sleep through one of them,” the “Three’s Company” star jokes of their twice-daily romps. “That's usually that one at 4 o'clock in the morning. But, you know, then again around 8 o'clock in the morning, I'm in the mood.”

A breast cancer survivor whose support of alternative treatments has caused controversy in the medical community, Somers has long sworn by bioidentical hormones, as documented in her 2006 book, Ageless: The Naked Truth About Bioidentical Hormones. She now claims that adding PT-141 shots — typically used to treat low sexual desire in cases without an underlying medical or emotional cause — has helped her get “in the mood.”

“I’m kind of in that groove, like when you were younger and you're in the mood all the time, and so is he because he's on hormone replacements,” she shared.

“I thought, ‘Wow, what a great thing.’ Because men have had Viagra, but this [is] actually a shot for both men and women that’s not a drug. It just stimulates that part of your brain that says, ‘Hey, I’m kind of in the mood.’ And so, isn’t that a wonderful thing? And it’s not a drug, so I love it.”

Sherry A. Ross, MD, a women’s health expert and the author of She-ology, thinks Somers is setting a good example by speaking out about her sex life — but cautions that not everyone may enjoy the same effects from the medication.

“I have to give Suzanne Somers credit for embracing sex and standing on a soap box to talk about it,” Ross tells Yahoo Lifestyle. “With the sexual injustice happening in the bedroom, women have not been given many viable options to help improve desire. Hypoactive sexual desire disorder (HSDD) affects over 40 percent of women with very few treatment options. Unlike men, women’s sexual desire, excitement and energy tend to begin in that great organ above the shoulders, rather than the one below the waist. The daily stresses of work, money, children, relationships and diminished energy are common issues contributing to low libido in women. It’s not a myth, after all, that women are more complicated than men.”
