This wraps up our mini-series on the latest peer-reviewed BDSM research. We started with the Jozifkova team’s findings on 24/7 dynamics and the Casey & Sagarin Authority Transfer framework. Since I skimmed and scanned dozens of studies, today I’ll tell you about five more studies that will fascinate you.
As a therapist, my lens on this research is straightforward: Does BDSM harm mental health? Does it damage relationships? Or does it do something else entirely?
The evidence is now unambiguous. BDSM practitioners show healthier psychological profiles, stronger relationship communication, and equal or superior well-being compared to non-practitioners.
Researchers have learned that some kink constructs lead to healthier relationships, which, of course, people in our world already knew. Now, studies have found evidence that affirms what the kink communities have said all along. Kink requires good communication skills, strengthens relationships, and correlates with healthier psychological profiles. The old theories and myths must be eliminated like toxic fungi. (In my humble opinion, as always.)
TL;DR BDSM practitioners are doing fine.
Here’s my pick of more BDSM studies, in the order they appeared.
June 2024: Communication is the mechanism
Carty and Davidson published findings from 376 participants (276 BDSM, 100 non-BDSM) showing that BDSM practitioners report higher sexual satisfaction because they communicate more directly about sex. Especially interesting is that they isolated the mechanism: it’s not the kink that transforms people, it’s the explicit negotiation, boundary-setting, and verbal processing that BDSM demands.

June 2024: Spanish mega-replication confirms healthier profiles
Lecuona and colleagues replicated the landmark Wismeijer & van Assen (2013) study with 1,884 Spanish adults and found the same results held. It is one of the largest BDSM studies ever conducted, so the fact that it confirmed Wismeijer & van Assen’s results is impressive!
BDSM practitioners were compared to non-BDSM folks. The BDSMers showed higher secure attachment, conscientiousness, openness, and subjective well-being, alongside lower insecure attachment, neuroticism, and rejection sensitivity as compared to non-practitioners.

October 2024: Consent norms evolve with relationship duration
Tarleton, Mackenzie, and Sagarin used experimental vignettes with 202 BDSM practitioners and found that consent practices are rated as significantly more flexible in established romantic relationships compared to pick-up play. In other words, you’re stricter about rules at first, and more likely to loosen up when you get to know and, most importantly, trust your romantic partner.
While anecdotal information abounds about the flexibility, playfulness, and evolution in BDSM relationships, this is the first empirical evidence that BDSM consent communication adapts across relationship stages. It’s a positive sign of relationship maturity

November 2024: BDSM builds stronger romantic connections
Westlake and Mahan surveyed 810 BDSM practitioners internationally and found that BDSM participation follows a stepwise learning trajectory over the years.
The study revealed that BDSM functions to build stronger connections between romantic partners. This includes increased trust, intimacy, communication, and the ability to meet each other’s needs. As the trust grows, people become more willing to experiment with wilder, riskier activities together.

November 2024: Two-thirds report positive mental health impact
Researchers Sprott and Randall analyzed data from 1,003 respondents in the 2016 National Kink Health Survey. They found that 66% of participants reported that kink sexuality had a positive impact on their mental health. Qualitative analysis identified multiple pathways through which kink contributes to well-being. This directly challenges the pathological model of BDSM that still lingers in clinical practice.

What the evidence shows
I’ve always said that science is our friend. Contemporary studies on Kink, Fetish, and other negotiated and consensual power relationship frameworks show that 140 years of doctrinal teachings about kink were false.
BDSM practitioners consistently demonstrate healthier psychological profiles, stronger communication skills, and equal or superior well-being compared to non-practitioners. Explicit negotiation builds communication competence, consent practices evolve adaptively in long-term relationships, and kink participation strengthens romantic bonds through trust-building and shared vulnerability.
The mechanisms are clearer with each new study. They give us new ideas, new foundations to build on, and new language. The evidence is unambiguous. BDSM is not a red flag for mental health or relationship dysfunction. For many practitioners, it’s the opposite.
