Short answer: For many couples, consensual kink is linked with greater sexual satisfaction rather than with harm. In a Norwegian national survey of 4,148 participants, over one in three reported at least one BDSM interest or behavior, and sexual satisfaction was positively associated with role-play and BDSM behaviors. A study of 543 Chilean kink practitioners connected frequency and variety of activities with higher satisfaction, with no differences across dominant, submissive and switch roles. The main risk is not kink itself but silence: unspoken desire, not shared fantasy.
Many people fear that a partner will find them “weird” for naming what genuinely arouses them. That fear is strikingly common — in Tehran, Toronto and Los Angeles alike —.
What Does Research Say About Kink and Couples’ Sexual Satisfaction?
The largest available picture comes from a national web-population survey in Norway, published in the Journal of Sex Research in 2022. Among 4,148 participants, over one in three endorsed at least one BDSM interest or behavior. The authors found no gender or educational-level differences between BDSM-oriented and “vanilla” participants; such interests were simply more common among younger respondents.
The same survey (Strizzi, Øverup, Ciprić, et al., 2022) found sexual satisfaction positively associated with role-play and with BDSM behaviors, and reported no significant link between any BDSM-related variable and relationship closeness. In Chile, a study of 543 kink practitioners (Catalán Águila, Fernández Agis & Strizzi, 2026) connected the frequency and diversity of BDSM activities with higher sexual satisfaction, with no significant differences across dominant, submissive and switch roles.
“BDSM interests and behaviors are relatively common and are linked with sexual and relationship satisfaction.” — Strizzi, Øverup, Ciprić, et al., Journal of Sex Research, 2022
This aligns with the Chilean authors’ own conclusion that non-conventional forms of sexuality such as BDSM should be respected and de-pathologised.
Limitations: Both surveys are cross-sectional, so they demonstrate association rather than causation, and the Chilean authors themselves call for more diverse, representative and longer-term research. It also remains possible that couples who already communicate openly are simply more willing to experiment.

Why Does Unspoken Desire Hurt a Relationship More Than Kink Itself?
One finding speaks directly to couples. In the Norwegian survey, an interest in role-play that had never been acted on was negatively associated with sexual satisfaction, whereas role-play and BDSM behaviors that were actually practiced were positively associated with it.
Closeness followed a similar pattern: lower relationship closeness was associated with an untried interest in role-play, while no BDSM-related variable was significantly associated with closeness. The evidence therefore does not suggest that consensual kink erodes intimacy; a fantasy kept secret appears to sit alongside distance rather than to create it.
“Lower relationship closeness was associated with an interest in role-play (but not having tried it). No BDSM-related variables were significantly associated with relationship closeness.” — Strizzi et al., Journal of Sex Research, 2022
A smaller study by Pascoal, Cardoso and Henriques (2015, Journal of Sexual Medicine) surveyed 68 BDSM community members (mean age about 33), who had waited on average six years before acting on their interest. Among men, distress in sexual functioning — except premature orgasm and anorgasmia — was significantly lower in BDSM contexts; among women it was statistically the same except for maintaining arousal. As a small convenience sample, it cannot be generalised.
Limitation: Correlation cannot establish direction — lower satisfaction and emotional distance may equally reduce a couple’s willingness to experiment.
In Tehran and across the Iranian diaspora, this pattern is often intensified by shame, which keeps “different” desires hidden even inside otherwise affectionate relationships.
What Does Psychoanalysis Say About Pleasure in Dominance and Submission?
Psychoanalysis explored this territory long before survey research did. In Three Essays on the Theory of Sexuality (1905, Standard Edition vol. 7), Freud discussed sadism and masochism together, noted that the two often appear in the same person, and observed that traces of them exist within “ordinary” sexuality.
What makes a sexual tendency problematic is its becoming exclusive and compulsive, not its mere existence. Read this way, conscious and mutually agreed kink can be a safe stage for playing with power, trust and the relinquishing of control.
From a psychoanalytic perspective, agreed kink can turn a hidden struggle over power into a conscious game played by shared rules — a stage on which two people safely experience what everyday life asks them to suppress.
How Can Couples Talk About Kink, and When Should They Seek Help?
The clinical experience of specialists suggests that kink is discussed most successfully the way any sensitive subject is: calmly, outside the bedroom, and without ultimatums.
Talk at a calm time outside the bedroom, when neither partner is aroused, exhausted or defensive, so the conversation is about curiosity rather than performance.
Negotiate each activity in advance and accept “no” without demanding justification; consent can be withdrawn at any moment, by either partner, including mid-scene.
Agree on a safeword and on aftercare beforehand, so limits are explicit and both partners know how reconnection will happen afterwards.
Professional help is worth considering when a desire mismatch has become constant tension, when one partner feels pressured to participate, or when shame blocks any conversation at all. A kink-aware specialist can help partners speak about fantasy without judgement and rebuild agreements that protect both of them.
Yes. In a Norwegian national survey of 4,148 participants, published in the Journal of Sex Research in 2022, over one in three participants endorsed at least one BDSM interest or behavior, with no gender or educational-level differences separating kink-oriented from “vanilla” respondents.
Does kink reduce a couple’s closeness?
The evidence does not suggest so. In the 2022 Norwegian survey, no BDSM-related variables were significantly associated with relationship closeness, although an untried interest in role-play was linked with lower closeness. Untried fantasy appears riskier than shared practice.
Does being dominant or submissive change sexual satisfaction?
In a study of 543 BDSM practitioners in Chile (Catalán Águila, Fernández Agis & Strizzi, Journal of Sex Research, 2026), frequency and diversity of kink activities were linked with higher satisfaction, with no significant differences across dominant, submissive and switch roles.
How do I bring up kink with my partner?
Choose a calm moment outside the bedroom and frame it as curiosity, not a demand. Share one interest, invite your partner’s fantasies, and accept “no” without requiring reasons.
Conclusion
Consensual kink is linked with higher sexual satisfaction for many couples and shows no sign of harming closeness. Silence about desire, by contrast, tends to hurt more than any difference in taste. Honest, safe conversation — with clear limits and reliable aftercare — is often the first step toward a relationship that feels more alive.
