Masturbation Month: The Science of Solo Wellness

Every May, the calendar flips to a quiet kind of awareness month — one that doesn't get pink ribbons, network coverage, or a White House proclamation. It gets a wink, maybe a joke, and then it's gone.

But National Masturbation Month is more than a punchline. It's the legacy of a U.S. Surgeon General who lost her job for telling the truth about human bodies, a San Francisco boutique that refused to let that be the end of the story, and three decades of accumulated research that has quietly moved self-pleasure out of the shame column and into the wellness column — right next to sleep, hydration, and walking 8,000 steps a day.

This is the case for paying attention to a month most people scroll past. Not because the topic needs a parade, but because the science is unambiguous, the cultural baggage is still loud, and education has always been the better answer to discomfort.

This guide is brought to you by the team at Duke & Duchess Intimates, where we believe intimate wellness is wellness — full stop. Below: the real origin story, what peer-reviewed research from 2022 through 2024 actually shows, the myths worth retiring, and how solo wellness practice fits into a fuller picture of physical and relational health.

A Month Born From a Surgeon General's Firing

The origin of National Masturbation Month is one of the more remarkable stories in modern public health — and it begins, of all places, at a United Nations conference.

December 1994: The Comment That Cost a Career

On December 1, 1994, U.S. Surgeon General Dr. Joycelyn Elders spoke at a UN World AIDS Day event in New York City. Asked whether teaching young people about self-pleasure could reduce risky sexual behavior, she gave a measured, science-grounded answer: that it is "a part of human sexuality and it's a part of something that perhaps should be taught," and that "we have tried ignorance for a very long time and it's time we try education."

Nine days later, President Clinton forced her resignation. The first Black Surgeon General in U.S. history was out of a job for telling the truth about a behavior practiced by the vast majority of human beings.

May 1995: San Francisco Pushes Back

The sex-positive education community refused to let the moment pass. In May 1995, the team at Good Vibrations — a San Francisco wellness boutique — convened to respond. Staff sexologist Dr. Carol Queen, Ph.D., later told the SF Standard: "It was an outrage to us — an outrage."

Their answer was the first National Masturbation Day on May 7, 1995. The month was chosen partly because, in Queen's words, "it's the merry, merry month of May." The single day eventually expanded into a full month — and then, as awareness spread globally, into International Masturbation Month. A separate National Masturbation Day, May 28, still anchors the observance at month's end.

What started as a protest is now, three decades later, a yearly nudge from the wellness community to talk openly about something most people already do quietly.

What the Science Actually Says

Thirty years after Dr. Elders' firing, the medical literature on solo wellness is no longer a debate. It's a body of peer-reviewed evidence that points consistently in the same direction: regular self-pleasure, for adults who want it, is associated with measurable physical and psychological benefits.

The Evidence by Benefit

"Solo Practice Is Sexual Health" — In Therapists' Own Words

"Masturbation can relieve pain and menstrual cramps, create a sense of well-being, improve sleep, reduce stress, and increase self-esteem."

— Dr. Laurie Mintz, Ph.D., Emeritus Professor of Psychology at the University of Florida and certified sex therapist, via drlauriemintz.com

That quote matters because Dr. Mintz is also the researcher who has documented something called the "orgasm gap" — the well-replicated finding that women orgasm far more reliably during solo practice than during partnered sex. Her clinical recommendation, echoed across the sex-therapy literature: "Women who pleasure themselves have more orgasms with partners as well." Self-knowledge feeds partnered satisfaction. They are not in competition.

Four Practical Takeaways From the Research

1. There is no "right" frequency. Cleveland Clinic and Medical News Today both confirm: no peer-reviewed evidence supports a frequency threshold above which solo practice becomes harmful for healthy adults.
2. Solo and partnered intimacy track together, not apart. The Herbenick 2022 nationally representative survey found women with more frequent partnered sex also reported more frequent solo activity — a complementary pattern, not a compensatory one.
3. The mood benefits are neurochemical, not psychological. Orgasm reliably triggers dopamine, oxytocin, and serotonin release while suppressing cortisol. This is biology, not vibes.
4. Body literacy translates. The pathway is consistent across the literature: know yourself → communicate with confidence → experience deeper partnered intimacy.

Solo Wellness Across Life Stages

Self-pleasure is not a single experience. What it offers, and what supports it, shifts across a lifetime.

Early Adulthood: Body Literacy

In your twenties and thirties, solo wellness is often the foundation of body literacy — the working knowledge of what your body responds to, what it doesn't, and how arousal builds. This is the period where self-knowledge becomes the input that makes communication with future partners possible.

Midlife: Stress, Sleep, and Hormonal Shifts

In your thirties through fifties, solo wellness commonly becomes a stress and sleep tool. Cortisol regulation, oxytocin release, and the simple act of taking 15 minutes for yourself in a demanding life chapter all add up. For women approaching perimenopause, regular arousal is also one of the simplest ways to support continued tissue health and blood flow — see our Pelvic Floor Health guide for the longer picture.

Postmenopause: Tissue Health and Continued Pleasure

After menopause, solo wellness shifts from optional to therapeutic for many women. Regular arousal supports blood flow to vaginal tissue, helps maintain elasticity, and contributes to the kind of ongoing intimate health that lets pleasure continue to evolve rather than fade. The Cleveland Clinic explicitly notes reduced vaginal dryness in older adults as a documented benefit. Our guide to Sexual Wellness After Menopause covers what helps in detail.

What Duke & Duchess Intimates Brings to Solo Wellness

A wellness-forward approach to self-pleasure means choosing tools and education with the same care you'd bring to any health practice. That's the lane we sit in.

• Personal massagers as self-knowledge tools. A massager is not a substitute for partnered intimacy — it's a discovery instrument. Research consistently shows that women who use vibrators become more reliably orgasmic, including during partnered sex, because they develop clearer body literacy. New to the category? Our How to Choose Your First Personal Massager guide is the no-judgment starting point.
• Body-safe materials matter, especially for solo use. Anything used on or near intimate tissue should be non-porous and medical-grade: silicone, stainless steel, or borosilicate glass. Porous materials can harbor bacteria and are difficult to clean fully. We curate around this standard — see What Does "Body-Safe" Actually Mean for the full breakdown.
• Lubricants are wellness products, not accessories. Water-based lubricants reduce friction, support tissue comfort, and make solo practice easier and more enjoyable — particularly during perimenopause and beyond, when natural lubrication shifts. Our Beginner's Guide to Lubricants walks through how to choose one.
• Education first, products second. The Wellness Hub exists because we'd rather someone leave with the right information than the wrong product. Solo wellness is a practice, not a purchase — and the tools work best when they support a habit that fits your body.

Getting the Most Out of Solo Wellness Month

1. Trade frequency anxiety for curiosity. There's no chart you're supposed to hit. Notice what your body actually wants this month.
2. Treat it like other wellness practices. Time of day, lighting, calm space — context shapes the experience.
3. Choose tools that match your body, not the algorithm. A first massager is not a final one. Comfort and material safety beat reviews.
4. Pair solo practice with sleep, not screens. The neurochemistry favors a wind-down, not a scroll-down.

Frequently Asked Questions

Is there a healthy frequency for solo wellness?

No medically established upper or lower limit exists for healthy adults. Frequency varies enormously by individual, life stage, partner status, hormonal cycle, and personal rhythm. The Cleveland Clinic and Medical News Today both confirm that no peer-reviewed evidence supports a frequency threshold above which solo practice becomes harmful. The wellness-forward question is not "how often," but "does this fit my own sense of wellbeing." If solo practice is interfering with daily life, relationships, or responsibilities, that is worth a conversation with a therapist — but frequency alone is not the metric.

Does solo wellness affect partnered intimacy negatively?

The research says the opposite. The 2022 nationally representative U.S. survey by Dr. Debby Herbenick and colleagues found that women with more frequent partnered sex also reported more frequent solo activity — the patterns are complementary, not compensatory. A 2023 peer-reviewed study found that mutual self-pleasure within relationships correlated with significantly higher sexual satisfaction. Sex therapists like Dr. Laurie Mintz routinely teach that solo practice is the foundation of partnered communication: "Sex therapists advocate that women first learn what they need by themselves, and then teach partners what this is."

What if I feel guilt afterward?

Post-activity guilt is one of the most common questions therapists get on this topic, and the research is consistent: guilt almost always traces back to internalized cultural, family, or religious messaging — not to the activity itself. A 2022 study found that higher frequency of solo practice was actually associated with lower body shame and higher body appreciation. If guilt surfaces, it's worth exploring where it came from rather than treating it as evidence the behavior is the problem. A therapist who specializes in sexuality can be enormously helpful here. The wellness framing: curiosity about your own body is an act of stewardship, not a moral failure.

Conclusion

Thirty years ago, a U.S. Surgeon General said out loud that human beings should be educated about their own bodies, and she lost her career for it. Three decades later, the science she pointed toward is settled: solo wellness is, for adults who want it, associated with lower stress, better sleep, healthier pelvic tissue, more reliable communication with partners, and a fuller relationship with one's own body.

May exists as a quiet annual nudge to bring this part of wellness out of the joke column and into the same conversation as any other practice that helps a person feel more at home in their own life.

If this month is the one where you decide to look at solo wellness with the same care you'd bring to sleep, movement, or nutrition, the Duke & Duchess Wellness Hub is here for the questions — and our team is here when you're ready for the tools to match.
