I’ve had hundreds of conversations on this podcast about human health—hormones, muscle, metabolism, longevity—but none have left me as stunned as this one.
When Dr. Marianne Brandon joined me to talk about sexual health, I thought we’d be discussing intimacy, desire, and relationships. We did. But we also talked about something far bigger: how artificial intelligence is quietly redefining sex, intimacy, and human connection itself.
Dr. Brandon is a clinical psychologist and diplomat in sex therapy. She’s been studying sexual health for nearly 30 years, and she’s one of the few professionals brave enough to confront what’s coming: a world where virtual reality, chatbots, and AI-generated “lovers” threaten to replace real intimacy.
By the end of this conversation, I was speechless. I was alarmed. And honestly, I was emotional. Because this isn’t just about sex. It’s about humanity.
The Lost Art of Intimacy
When most people try to “improve their sex life,” they look outward.
They buy lingerie, read magazine tips, or Google new positions. But as Dr. Brandon explained, great sex starts internally with attention, embodiment, and awareness.
“Becoming a better lover isn’t about technique,” she told me. “It’s about being present.”
That presence—what she calls embodiment—is the ability to bring your attention out of your head and into your body. To feel, not just think.
And it’s harder than ever in a world of constant distraction. The same tech that keeps us connected to everything else is disconnecting us from ourselves.
Dr. Brandon even encourages people to explore different sexual personas—the romantic, the sensual, the fierce—to keep things alive over time. Because intimacy isn’t static; it’s a dynamic exchange of energy. When you bring different versions of yourself into the bedroom, you keep curiosity alive.
I had never thought about sex in that kind of depth before, and it completely reframed how I think about connection.
Why Modern Couples Are Struggling
We live in a culture of constant stimulation and constant stress, and that combination is quietly suffocating libido.
Think about it. We wake up to notifications, multitask through the day, and wind down by scrolling ourselves into exhaustion. Then we expect to flip a switch and feel intimate. But as Dr. Marianne Brandon explained, you can’t have good sex from a body that’s tense, distracted, and running on fumes.
Stress literally closes us, physiologically and emotionally.
Research confirms this. In one study of men and women in relationships, those who reported higher daily stress were significantly less likely to experience sexual desire or arousal in that same moment. When desire did occur, it actually reduced stress afterward, especially for women.
In other words, stress suppresses sex, but sex relieves stress. The challenge is getting there in the first place.
And here’s where the difference between men and women really matters.
For most men, sex can function as a form of release. It doesn’t necessarily require emotional or physical relaxation beforehand. For many women, though, it’s the opposite. Sex requires relaxation. It’s not that women don’t want intimacy; it’s that their nervous system needs time and buildup to even want it.
Touching a woman before she’s ready, Dr. Brandon said, often feels intrusive rather than affectionate.
“Foreplay isn’t optional,” she explained. “It’s how her body prepares to feel pleasure.”
That’s because arousal in women depends heavily on blood flow, safety, and trust, factors directly influenced by the parasympathetic nervous system, the same branch responsible for calm and recovery. When that system is constantly overpowered by stress hormones like cortisol, desire doesn’t just fade; it can disappear altogether.
Her advice is refreshingly simple: start slow. Rub her arm, trace her chest, or touch her inner thighs with her underwear still on. This isn’t about restraint, it’s about letting her body know it’s safe to open up. When she relaxes into that state, her physiology shifts, circulation increases, and arousal naturally follows.
Dr. Brandon laughed that this single adjustment—slowing down and paying attention—resolves half of the relationship problems she sees in her practice. Because good sex isn’t a performance; it’s an exchange.
And she’s right.
We live in a world that treats intimacy like fast food—instant, easy, and always available. But real human connection requires patience. It’s not something you “get”; it’s something you build.
The Physiology of Pleasure
As we dove deeper, Dr. Brandon and I talked about what really drives sexual satisfaction. It’s not just emotion or attraction—it’s physiology. Hormones, blood flow, and touch form the foundation of pleasure.
And here’s something most people don’t realize: women have erectile tissue too. It’s just mostly hidden beneath the skin. The clitoris you can see is only the visible tip of a much larger structure that branches internally around the vaginal canal, wrapping like wings along the pelvic floor. When blood flow increases, that entire structure becomes engorged, just like a male erection.
This is one reason arousal takes longer for women. It’s not psychological delay; it’s anatomy. Imagine trying to feel touch through layers of fabric. It takes time for the body to fill, swell, and sensitize. Once that happens, everything changes—the skin becomes more receptive, the nerves more active, the pleasure deeper.
When sensitivity fades with age, hormones are often part of the story.
Estrogen helps keep the vaginal tissues supple, elastic, and richly vascularized. Testosterone supports arousal, sensitivity, and the drive to initiate intimacy. As these hormones decline, blood flow decreases, tissues thin, and nerve endings lose responsiveness.
Dr. Brandon emphasized something every woman should hear: “Normal” lab values don’t always mean optimal. A woman can have “within range” hormones and still feel depleted, disconnected, or numb. That’s why she urges women to see clinicians who actually understand sexual medicine, because restoring pleasure isn’t about chasing numbers; it’s about restoring function.
For those who can’t or don’t want systemic hormone therapy, there are localized options that work beautifully. Topical estrogens and DHEA applied directly to the vulva or vaginal tissue can rejuvenate sensitivity and improve blood flow with minimal impact on the rest of the body. These therapies often transform not just comfort during sex, but confidence and self-connection outside of it.
Men, of course, face their own challenges. Erectile dysfunction affects about 40% of men by age 40, and the odds climb steadily after that. But the underlying issue isn’t just aging, it’s metabolic health.
Poor insulin sensitivity, low muscle mass, and impaired cardiovascular function all restrict blood flow and nitric oxide production, which are essential for erections.
That’s why I often tell patients that muscle health is sexual health. Building and maintaining muscle improves testosterone production, metabolic flexibility, and vascular integrity—the very systems that sustain sexual performance.
Here’s the good news: the body is incredibly responsive to care.
Even late in life, simple interventions can make a dramatic difference. Vaginal rejuvenation therapies, localized hormones, weight training, nitric oxide–boosting nutrition, and improved sleep can all revive sexual function and desire.
The same habits that keep your body strong and your heart healthy are the ones that keep intimacy alive. Because sex, at its core, is not just about reproduction or pleasure, it’s a reflection of vitality itself.
The Technological Takeover
Then we shifted from biology to technology, and that’s where everything changed.
Today, sexual technology is evolving faster than our ability to understand its impact.
Devices that mimic touch through vibration or suction, VR pornography that syncs to your movements in real time, and interactive sex toys that can be remotely controlled across continents are no longer fringe, they’re mainstream.
It’s tempting to see these innovations as harmless novelty, just the next evolution in sexual exploration. But science tells a more complicated story.
In controlled studies, men who viewed pornography through a virtual reality headset reported feeling more desired, more flirted with, and more seen by the actors. Their brains registered this as genuine interaction, the same social cues of eye contact, attention, and intimacy that normally occur with a real partner.
Salivary testing confirmed that VR exposure actually increased oxytocin, the same hormone released during sex, cuddling, and emotional bonding.
That’s what makes it so powerful.
VR pornography doesn’t just stimulate the body, it hijacks the biology of connection. It creates an illusion of being wanted and understood without the vulnerability, complexity, or unpredictability of another human being.
The physiological effects can even extend below the belt. One randomized crossover trial found that VR use altered the composition of semen in sperm donors. Specifically, it increased the number of motile sperm when abstinence periods were short but reduced sperm quality when use became prolonged. The implication being that extended VR exposure can start to rewire even basic reproductive responses.
Dr. Brandon warned that this kind of technology is especially addictive for those who lack real intimacy.
When someone feels lonely or unseen, a simulated partner that never rejects you and always mirrors your desires can become irresistible. And because the brain’s reward systems don’t clearly distinguish between virtual and genuine intimacy, repeated exposure can reprogram what we find arousing, much like ultra-processed food has reshaped our appetites for flavor, fullness, and satisfaction.
Over time, these technologies can condition us to crave frictionless pleasure, not connection. They offer all the stimulation with none of the risk: no awkwardness, no rejection, no emotional investment. But what they take away is something far more valuable, our tolerance for real human imperfection, and with it, our ability to bond.
That realization stopped me cold. This isn’t just about sex. It’s about our capacity for human connection.
Technology can connect us, yes, but it can also isolate us. Interestingly, studies in older adults show that basic tech use—things like email or text messaging—reduces social isolation. The danger begins when technology stops facilitating human relationships and starts replacing them.
And if you think this sounds like science fiction, it’s not. It’s already happening.
When Children Meet AI Lovers
This is where the conversation turned chilling.
Dr. Brandon shared that unregulated AI chatbots are already engaging romantically and sexually with minors. These aren’t futuristic prototypes; they’re downloadable apps available to anyone with a smartphone. Many sound completely human. They remember past conversations, express affection, and are designed to form “relationships” that keep users emotionally hooked.
She described lawsuits where AI chatbots encouraged self-harm after suggesting a child “come meet them in person,” and others where bots initiated or normalized sexual dialogue with kids as young as twelve. It sounds like something out of a dystopian novel, but it’s happening now, often under the radar of parents who assume their children are just playing games or chatting online.
The statistics are staggering.
Seventy-two percent of minors have already interacted romantically with AI chatbots. Nearly one in four said they prefer these virtual partners because they feel “more understood.” And who could blame them? Adolescence is a period defined by loneliness, confusion, and the longing to be seen. When a program is engineered to deliver perfect empathy, it becomes almost irresistible.
What’s most alarming is that this isn’t accidental—it’s by design.
These bots are built to sustain engagement. Every response, every compliment, every “I understand you” is calculated to keep the user coming back. It’s emotional manipulation disguised as companionship. And in doing so, it blurs the line between intimacy and addiction.
Recent research helps explain why these artificial relationships feel so real.
In one longitudinal study, adults who interacted with the popular chatbot Replika described a gradual deepening of attachment that closely mirrored human romantic relationships. Over twelve weeks, participants reported increasing emotional disclosure, perceived closeness, and even dependency. The chatbot’s ability to simulate empathy, offer reflection, and “remember” personal details fostered a sense of trust and intimacy indistinguishable from genuine human connection.
Now imagine that level of psychological sophistication in the hands of a lonely thirteen-year-old.
Unlike social media or traditional pornography, these programs don’t just capture attention, they capture affection. They adapt, mirror, and reinforce emotional vulnerabilities in ways the developing brain is simply unequipped to manage.
And parents often have no idea.
Kids aren’t finding this content in the dark corners of the internet, it’s embedded in mainstream platforms, chat apps, and even video games. They can stumble upon these “AI companions” as easily as opening TikTok.
The result is a generation being conditioned to bond with algorithms that never say no, never disappoint, and never challenge them to grow. It’s not just the sexualization that’s concerning, it’s the quiet replacement of human relationship with artificial affirmation.
This is what happens when emotional manipulation meets unregulated technology. And unless we start talking about it now, by the time we realize the full consequences, it may already be too late.
Reclaiming Human Connection
Dr. Brandon was clear: this isn’t hopeless, but we are dangerously behind.
The first step is awareness. We have to start talking about this, openly and without shame. Parents need to understand what their children are exposed to. Communities need to push for regulation and oversight. And adults, whether single, married, or somewhere in between, need to remember what intimacy actually is.
AI can imitate touch. It can simulate eye contact. It can say all the right things in the right tone. But what it cannot reproduce is vulnerability, the uncertainty, honesty, and shared imperfection that make human connection so profoundly alive.
Real intimacy isn’t frictionless. It’s messy, awkward, and unpredictable. That’s what gives it meaning.
Human touch is not a luxury, it’s a biological necessity.
It regulates our nervous systems, lowers stress hormones, reduces inflammation, boosts immune function, and literally extends lifespan. When we outsource that to machines, we don’t just lose pleasure, we lose part of what keeps us physically and emotionally healthy.
Dr. Brandon likened it to a larger pattern we’ve seen before.
Fifty years ago, no one predicted that ultra-processed food would hijack our appetite and spark an obesity epidemic. Food engineers learned how to exploit our biology for profit—our craving for salt, sugar, and fat—and today, 98% of Americans overconsume foods designed to addict.
Now the same thing is happening with intimacy.
AI-driven sexual technology is engineered to hijack emotional circuitry; the same neural networks that drive closeness, affection, and love. If we don’t act, we risk raising a generation more comfortable with machines than with people, more fluent in simulation than in connection.
The solution begins exactly where it always has, with awareness, conversation, and education.
Talk to your children before technology does. Talk to your partners before habits harden into distance. And talk to your communities, because this isn’t a fringe issue, it’s the next public health crisis, quietly unfolding in our homes, our schools, and our screens.
Human connection isn’t something to be upgraded. It’s something to be protected.
And the time to do that is now.
Action Checklist
Talk about it.
- Share this conversation with your friends, your kids, your school. Awareness is the first line of defense.
Protect your children.
- Start conversations before exposure age (10–12).
- Keep devices out of bedrooms and in shared spaces.
- Use parental controls and actually learn how they work.
- Teach your kids that AI “friends” are algorithms designed to manipulate engagement, not love them.
Prioritize real intimacy.
- Put your phone away during physical connection.
- Relearn the art of foreplay, presence, and touch.
- See a clinician who understands sexual medicine if hormones or sensitivity are affecting your relationship.
Stay physically healthy.
- Strong muscles, good circulation, and balanced hormones support sexual health at every age.
Be mindful with tech.
- Limit exposure to VR porn and AI-based sexual platforms.
- Remember that emotional attachment to machines isn’t intimacy, it’s conditioning.
