The Kinks Sex Researchers Won't Study | Dr. Debra Soh

Overview

Dr. Debra Soh, author of Sexinction and The End of Gender, argues that Western society is seeing a broad decline in consensual sexual activity and dating—especially among younger generations. She describes this as a “sex extinction” trend, which she finds paradoxical given how openly sex is marketed and how accessible it appears to be.

1) Critique of “sex positivity” and sex-research culture

Soh says her support for “sex positivity” decreased over time. She argues that academia and parts of sex research discourage certain lines of inquiry and that researchers face political and institutional pressure to accept assumptions about sexuality without critical scrutiny.

She contends this can shape biased public messaging, including ideas that:

• “anything goes,”
• paraphilias and unusual kinks should be treated as unconditionally healthy/valid,
• people should not judge.

Soh argues such messaging may weaken sexual boundaries—particularly for young women—by encouraging compliance with partners’ desires to avoid being labeled “sex negative.”

2) Declining sex and dating: not just social reasons

When discussing lower sex rates among both married and single couples, Soh argues the trend cannot be explained by dating convenience or money alone.

She points to multiple contributors:

• Biological/environmental factors: endocrine disruptors, environmental toxins, and pharmaceutical residues in wastewater.
• Pharmaceutical exposure: she mentions birth control and antidepressant use as potentially affecting sexual development and motivation, while emphasizing she is not advocating that people stop medication.
• Motivation and mental health: she links reduced sexual interest to broader nihilism and motivation problems, especially among Gen Z men.
• Online media effects: social media and highly engaging content may reduce face-to-face intimacy (e.g., cuddling and conversation). She also argues sex requires effort and mood compared with passive phone use.

3) “Rape crisis” discussion: brought in as evidence against purely biological framing

In response to questions about the relationship between sex crime/rape climate and declining consensual sex, Soh suggests it may be useful to discuss rape not only as something “in the water,” but to explore whether mechanisms (e.g., biological or genetic disruptions) could contribute to shifts in sexual behavior.

She also emphasizes that hypotheses should account for multiple interacting causes, rather than a single explanation.

4) Porn and “sexual script” claims

Soh discusses earlier findings that porn consumption correlated with higher sexual activity, but she argues those results may not generalize to younger generations who may be exposed to pornography at very young ages.

Her view includes the possibility that:

• early, frequent exposure may warp expectations,
• this could contribute to reduced interest or less satisfying sex later.

The hosts and guest also debate whether sexual statistics might be biased by who is included—such as couples with easy access versus those who struggle to find partners.

5) Paraphilias, kink, and “values vs. consent”

A major theme is Soh’s argument that sexual preferences can be shaped by psychological and developmental factors—not just random preference.

She often characterizes many kinks as forms of sexual masochism/sadism or as outcomes of prior experiences (including trauma or boundary violations), while still insisting that consent is necessary.

She also critiques certain “liberatory” narratives—for example, pegging-as-revenge framings—arguing that some kink use may be motivated by humiliation or power dynamics rather than empowerment.

6) Trauma, hypersexuality, and taboo topics

Soh claims childhood sexual assault can contribute to hypersexuality and riskier sexual behavior.

She argues that society tends to treat women’s hypersexuality as “empowerment,” while male hypersexuality is dismissed or less discussed—creating asymmetry in how trauma is acknowledged.

She also argues that messaging encouraging early sexual monetization (such as platforms selling sexual content) can normalize harmful patterns.

7) Specific sexual myths addressed: “bed death” and sexuality differences

Soh responds to claims such as “lesbian bed death” and general differences between men’s and women’s sex drives.

Key points she argues:

• interest declines for both sexes over time, but men often maintain a higher baseline drive;
• relationship satisfaction and emotional factors strongly influence women’s desire—less about raw attractiveness, more about whether they feel valued, fulfilled, and emotionally/relationally supported;
• lesbians may have lower average sex drive and may prioritize emotional fulfillment more, with penetration described by Soh as often exhausting.

8) Men “don’t really have less sex,” but survey reality is complex

The discussion includes debate about measurement and causality, including:

• whether married couples appear to have more sex due to access and selection effects,
• whether pornography/prostitution might substitute for partner sex.

Soh argues that masturbation and sex acts across categories are declining even in adolescence, suggesting environmental/hormonal influences rather than substitution alone.

9) Ending: dating advice and credibility concerns

Near the end, the host shifts from sexual theory to practical dating success. He cites Soh’s perspective on what helps a man avoid being seen as “creepy,” including:

• being fit,
• dressing well,
• being sane/reasonable/intelligent,
• using apps,
• plus real-life social interaction to build competence.

Soh emphasizes consistency—diet, sleep, and exercise—as foundational for decision-making and motivation.

She closes by reiterating her central thesis: mainstream sex narratives and sex research may be distorted by incentives and conformity pressures, and her goal is to encourage a more critical, evidence-driven approach.
