Lab Notes from the XX Lab

What I Learned from Dr. Cindy Meston About Female Sexuality

One of the things I love most about hosting my new podcast The XX Lab is that I get to spend time talkign science with people whose work has been foundational in how I think about the world. My recent conversation with Dr. Cindy Meston did exactly that — getting to learn from her again made me feel like a grad student all over again, (which hasn’t happened to me in a while, as I am deeply middle-aged).

If you’re not familiar with her work, Cindy is a Professor of Clinical Psychology at the University of Texas at Austin, where she directs the Sexual Psychophysiology Laboratory, which is one of the only labs in the entire world devoted exclusively to studying women’s sexual health from both a psychological and a physiological angle. She is currently ranked the #1 most highly cited scholar in the world in sexual function research. She’s also the co-author of Why Women Have Sex — a book The New York Times called the most thorough taxonomy of female sexual motivation ever compiled.

In other words: if there is one person on this planet whose opinion on this topic should outrank yours, mine, and your gynecologist’s group chat, it’s her.

For nearly three decades, Cindy has been chasing a question that sounds deceptively simple: what actually drives women’s sexual desire, arousal, pleasure, and satisfaction? Turns out, a lot of what we think we know is wrong — not because anyone lied to us exactly, but because most of what passes for sex education in this country was built around a male blueprint and we all just quietly assumed it applied to us too. Here are some of my biggest takeaways from our conversation.

1. The Myth That Women Have Lower Sexual Desire Than Men

One of the most common assumptions about sexual desire is that women simply have less of it than men. The reality, according to Meston, is more nuanced (and more interesting). Women’s desire tends to be far more responsive to context than men’s. Men are more likely to experience spontaneous desire, that out-of-nowhere “I’m interested” feeling, while women’s desire tends to show up in response to what’s actually going on around them: stress, relationship quality, fatigue, body image, emotional connection. All of it.

This is both the bad news and the good news. The bad news is obvious — when life is stressful (and whose isn’t), desire can vanish entirely, and you can start to wonder if something is wrong with you. The good news is that creating the right context can bring it back, which is not something you can say about most things that go missing in adulthood. Female sexuality isn’t weaker than male sexuality. It’s just more sensitive to the conditions it’s unfolding in, which is a completely different thing, and one worth sitting with.

2. One of the Best Sexual Enhancers Might Be Exercise

This one genuinely surprised me. Research out of Meston’s lab has shown that a single bout of exercise — in one study, just 20 minutes on a treadmill(!!) — can measurably increase genital arousal in women before sexual activity. Why? Because arousal depends in part on blood flow and activation of the sympathetic nervous system, the exact same system that fires up when you exercise. Your body, as it turns out, doesn’t draw a hard line between a hard workout and... well, you can finish that sentence yourself.

Here’s the part that really got me: the effect is strongest in women whose arousal is already compromised. Her lab found it most pronounced in women reporting more sexual dysfunction to begin with, and in a separate trial, women taking SSRIs or SNRIs for depression — medications notorious for flattening sexual response — showed real improvements in desire and arousal when they exercised beforehand. So if you’re struggling with arousal, whether it’s the antidepressants, the hormonal birth control, or perimenopause doing it to you, a brisk workout before intimacy might actually help. It’s a good reminder that sexual functioning isn’t some separate, mysterious system walled off from the rest of your body. It is your body.

3. We’ve Been Defining “Good Sex” Through a Male Lens

One of my favorite moments in the interview came when we got into orgasm — specifically, the quiet assumption baked into so much of our culture that you can measure the quality of a sexual experience by whether or not a woman had one. For men, orgasm and satisfaction tend to be tightly linked, so it’s an easy metric to reach for and an even easier one to apply to everybody. But for women, Meston pointed out, the relationship is far messier and more variable than that. Some women orgasm easily. Others don’t. Some have multiple orgasms in a single encounter; others rarely have one at all. And plenty of women report deeply satisfying experiences that don’t involve orgasm in the slightest.

When we define good sex solely by orgasm frequency, we are — without really meaning to — imposing a standard built for male sexuality onto an entirely different system. A better question, and one I’ve started asking myself, is simply whether the experience felt pleasurable, meaningful, and satisfying to the person actually having it. Radical, I know.

4. Some Women Are Simply More Orgasmic Than Others

This was another good reminder that biology is doing more of the driving here than we like to admit. Women’s capacity to experience orgasm varies considerably from woman to woman, and some of that variation appears to run in families — which is a strange thing to learn about your own body secondhand from a research talk. None of this means your sexual experience is predetermined or fixed in stone. But it does mean you shouldn’t assume everyone is starting from the same baseline, because they’re not.

Too often, women compare themselves to some imagined universal standard — usually cobbled together from a movie scene, a friend’s overshare, or whatever the internet has decided is normal this week — and quietly conclude that something is wrong with them. Most of the time, nothing is. It’s just normal human variation, the same way some people are naturally deeper sleepers or have a higher pain tolerance. You wouldn’t shame someone for that. Apply the same grace here.

5. Communication Is More Important Than Technique

People go looking for the perfect technique, the perfect position, the perfect trick, as if there’s some secret move out there that unlocks great sex for everyone, every time, indefinitely. What Meston’s research consistently points to instead is something far less glamorous and far more powerful: communication. Partners are not mind readers, no matter how long you’ve been together or how well you think you know each other’s bodies. The people with the best sexual relationships tend to be the ones willing to actually talk — about what they enjoy, what they don’t, what they need, and what’s changing.

And things do change, especially as women move through different hormonal stages of life. What worked at 25 may not work at 45. What felt pleasurable before childbirth may feel entirely different afterward. What worked before menopause may not work during it. None of that is a failure to be managed quietly and alone — it’s just information. Communication is what allows two people to actually keep up with it together, instead of one person silently adapting while the other wonders what changed.

6. Sexuality Is Shaped by the Stories We Tell Ourselves

One of the concepts we got into was sexual self-schemas — essentially the set of beliefs and expectations about sexuality that each of us carries around, built up over years out of family, relationships, culture, religion, and personal history. Some schemas support healthy sexual functioning. Others quietly sabotage it without you ever clocking why. A woman who unconsciously associates sexuality with shame, obligation, fear, or guilt is going to have a fundamentally different experience than one whose beliefs are rooted in curiosity, pleasure, and connection — even if their circumstances, on paper, look identical.

The stories we carry matter more than we give them credit for. And the unsettling part is that most of us never actually chose ours. We just absorbed them somewhere along the way and started living as if they were facts.

7. Writing Can Be Surprisingly Healing

This was probably the most moving part of our conversation. In a randomized clinical trial, Meston’s lab had women with a history of childhood sexual abuse complete just five 30-minute sessions of structured writing. Some wrote about the trauma itself; others wrote specifically about how the abuse had shaped their beliefs about their own sexuality. Both groups saw real improvements in depression and PTSD symptoms — but the women who wrote about their sexual self-schema were significantly more likely to recover from sexual dysfunction altogether.

At first, this seems like an odd result. How does journaling fix something that feels so physical, so far outside the reach of a notebook and a pen? But writing helps people organize experience, process emotion, and build a coherent narrative out of things that previously felt scattered and unspeakable. In some cases, putting an experience into words appears to help women reconnect with parts of themselves that became disconnected through pain, shame, or years of quiet avoidance. It’s a powerful reminder that healing isn’t always medical. Sometimes it starts with a blank page and the willingness to be honest on it, which is a much harder thing to do than it sounds.

The Big Takeaway

If there was one overarching lesson from my conversation with Dr. Cindy Meston, it’s this: female sexuality is not simply a weaker, dimmer version of male sexuality. It operates differently — on its own terms, by its own logic. Women are not broken men. Women are women, full stop. And understanding female sexuality requires actually taking women’s experiences seriously on those terms, instead of measuring them against a standard that was never built with us in mind in the first place.

That’s a lesson that extends well past the bedroom. It’s a lesson that applies to how we study women, how we care for women, and how we understand ourselves. And it’s a big part of why I think every woman — and, honestly, every man who loves one — would get something out of this conversation.
