Key Takeaways
- ✓Sex Recession Scale: The decline in sexual activity is not a redistribution from partnered sex to solo activity — the total aggregate has shrunk. Every category measured has fallen: intercourse, oral sex, partner and solo masturbation, even among adolescents. 37% of adults now have weekly sex, down from 55% in 1990. 48% of married couples had no sex in the past month, and 67% of Gen Z would choose sleep over sex.
- ✓Hormonal Birth Control and Mate Selection: Women on the pill, which halts ovulation, show blunted sexual signaling and altered mate preferences — trending toward provisioning over physical protection cues. Men unconsciously detect ovulation through scent, appearance, and gait, and increase mate-guarding behaviors accordingly. Women who have been on the pill since adolescence and come off it when trying to conceive risk discovering they are no longer attracted to their chosen partner.
- ✓Hypergamy and the Coupling Gap: As women increasingly out-earn men — women earn roughly £1,500 more per year than men up to age 30 — the pool of men women consider viable partners shrinks. This creates a small cohort of high-status men with disproportionate options, a large cohort of women unable to find suitable partners, and a bottom 40% of male earners dating the top 20% of female earners in hypogamous arrangements. Men in relationships where they are not the primary earner are 50% more likely to use erectile dysfunction medication.
- ✓Male Sedation Hypothesis: Historically, large populations of sexless young men correlated with social unrest and antisocial behavior. The absence of that pattern today, despite record male sexlessness, suggests behavioral sedation through screens, video games, porn, and cannabis. Porn activates the same brain networks as real sex, delivers orgasm without social effort, and produces post-orgasm lethargy — reducing motivation to pursue real-world status, relationships, and achievement across the board.
- ✓Endocrine Disruptors and Testosterone Decline: Testosterone levels have declined measurably over 40 years, with the steepest drop in the last 20. Researchers have controlled for age, diet, weight, exercise, alcohol, smoking, and cannabis, and still identify an unexplained environmental factor. Pharmaceutical waste in water supplies has been shown to feminize and masculinize fish populations and suppress courtship behavior. A separate, underexplored mechanism: men's testosterone and sex drive are suppressed by proximity to infertile or absent women, meaning widespread hormonal contraception may be compounding male hormonal decline.
What It Covers
Dr. Debra Soh, neuroscientist and author of *Sextinction*, examines the documented sex recession affecting all developed nations, where 1 in 3 men and 1 in 5 women report no sex in the past 12 months. The conversation covers contributing factors including porn, hormonal birth control, endocrine disruptors, hypergamy, social media, and declining testosterone over the past 40 years.

- •Porn's Mechanism vs. Addiction: Porn functions as a sedating coping mechanism for anxiety rather than a clinical addiction. Men who eliminate porn report increased motivation to approach women in person, suggesting the availability of easy sexual release reduces the drive to tolerate social risk. The progressive escalation toward more extreme content is not habituation — it is a gradual self-revelation of pre-existing preferences that users were initially reluctant to acknowledge, even to themselves.
- •Social Media and Perceived Mate Value: Roughly 1 in 10 men report reduced interest in sex with their actual partner after viewing social media influencers. Women report feeling less sexually desirable after social media use. The mechanism is upward comparison against curated, heavily edited presentations. Men conditioned to assess female attractiveness through optimized social media profiles can develop an "ick" response to real partners whose online presence does not match the artificially elevated standard they have been trained to expect.
Notable Moment
Dr. Soh reveals that in her own research data, interest in BDSM and kink correlates more strongly with severe childhood physical abuse than either pornography problems or convictions for child sex offenses. She frames this not as judgment but as a call for people to examine whether their sexual preferences are processing unresolved trauma rather than reflecting authentic desire.
Episode Transcript
Is people having less sex a big deal? It is a big deal. Well, ask anyone who's not having sex if it's a big deal. I think they'll tell you, yeah, it is a problem, especially considering that it is young men who are typically in the their prime and at the peak of their sexual drive. So not only is it, I think, quite frustrating for them, but also when you're in a situation like that where you're struggling, and it's not just about the sex, it's also about the connection and the emotional intimacy and the larger feeling of connectedness and community. So, Sextinction is very much about the sex recession and the fact that young people, millennials and gen Gen z in particular, are having less sex than previous generations. And I was skeptical at first. I thought that this talk about the sex recession and sexlessness was overblown. But after I sat down, I got a chance to go through the data myself, look at the media reportage, talk to people. And we see consistently with multiple datasets that one in three men and one in five women have not had sex in the past twelve months, which is a large number of people. And so I was interested with this book. What is taking the place of sex? Mhmm. And what what does that say about where we're headed in the future? How different is modern sexual activity to what we understand about the past? Well, in terms of, say, the outlets that we have available. So the one question has been, is sex really on the decline, or is it that other outlets are taking the place, like porn, muscle, masturbation, things like OnlyFans or now AI companions. So each of these subjects have a different chapter in the book to themselves and in myself explaining, trying to understand, what the trend is about. Is it convincing? I test them out myself, which was a lot of fun in many cases. Mhmm. Going through the scientific research in terms of what we do know about these technologies, and then also talking about the evolutionary biology and psychology that is underpinning them. So what makes these technologies alluring to human beings, and why is it that it's potentially dangerous or distracting us from real life sex? How different is the amount of sex, person on person sex, that modern people are having compared with what we understand about the past? Well, everyone across the board is having less sex. So regardless of whether you are married or in a relationship or single, it's in Eastern countries, Western countries, basically all developed countries, and all age cohorts. But as I mentioned, most, more specifically among young people. But your question earlier about, you know, is it taking the place of potentially masturbation or other outlets or other sexual outlets, and if you look at studies that are asking about adolescent sexuality so this is a understandably, …
