A sadomasochist is someone who derives sexual arousal or emotional satisfaction from activities involving the giving or receiving of pain, restraint, or psychological power exchange. The term fuses “sadism” (pleasure in inflicting sensation or control) and “masochism” (pleasure in receiving it), and many people who identify this way experience both sides. Far from being rare or pathological, sadomasochistic interests are remarkably widespread: large population surveys find that roughly 40 to 70 percent of adults have fantasized about some form of bondage, dominance, or pain play, and about one in five report having actually tried it.
How Common Sadomasochistic Interests Actually Are
Public conversation tends to treat sadomasochism as a fringe interest, but the numbers tell a different story. A large Belgian general-population survey found that nearly 47 percent of respondents had tried at least one activity falling under the bondage-discipline, dominance-submission, or sadomasochism umbrella, and another 22 percent had fantasized about it without acting on it. About one in eight reported engaging in such activities on a regular basis, while roughly 8 percent self-identified outright as practitioners.1PubMed. Fifty Shades of Belgian Gray: The Prevalence of BDSM-Related Fantasies and Activities in the General Population A systematic scoping review pulling together data from multiple countries placed the fantasy rate between 40 and 70 percent for both men and women, with about 20 percent reporting hands-on experience.2PubMed. A Systematic Scoping Review of the Prevalence, Etiological, Psychological, and Interpersonal Factors Associated with BDSM
Those figures suggest a huge gap between private interest and public identity. Many people who have tried light bondage or playful power dynamics during sex would never call themselves sadomasochists. Whether someone adopts the label depends on how central these interests feel to their sexuality, how embedded they are in a community, and how comfortable they are with a word that still carries stigma. The takeaway is that the underlying curiosity is ordinary, even if the terminology sounds extreme.
What Psychology Research Finds About Sadomasochists
For most of the twentieth century, mainstream psychiatry classified sadomasochistic desire as a mental disorder, full stop. That view has shifted substantially. The current diagnostic framework draws a line between having an unusual sexual interest and experiencing distress or causing harm because of it. Desire alone is not a disorder. And the psychological data on people who actively practice sadomasochism are surprisingly positive.
A well-known Dutch study comparing over 900 practitioners with more than 400 non-practitioners found that the sadomasochist group scored lower on neuroticism, higher on extraversion and openness to new experiences, more conscientious, less sensitive to rejection, and reported greater overall well-being. The one area where they scored lower was agreeableness, which researchers interpreted not as hostility but as greater comfort with asserting boundaries and preferences.3PubMed. Psychological characteristics of BDSM practitioners A 2024 replication study confirmed the same pattern: practitioners showed higher secure attachment, greater conscientiousness and openness, and better well-being, while also demonstrating lower levels of insecure attachment, rejection sensitivity, and neuroticism. The researchers concluded that practitioners share the same underlying psychological structure as non-practitioners but tend toward more functional profiles.4PubMed. Not Twisted, Just Kinky: Replication and Structural Invariance of Attachment, Personality, and Well-Being Among BDSM Practitioners
A systematic review drawing on multiple studies echoed these results, adding that practitioners were less anxiously attached in their relationships and had a lower need for external approval.5Sexual Medicine. Bondage-Discipline, Dominance-Submission and Sadomasochism (BDSM) From an Integrative Biopsychosocial Perspective: A Systematic Review None of this means every sadomasochist is a paragon of mental health. But the consistent finding across multiple samples and countries is that the population as a whole looks at least as psychologically healthy as the general public, and on several measures, slightly healthier.
How the Brain Handles Pain During Sadomasochistic Arousal
The question that puzzles most people is straightforward: why would pain feel good? The neuroscience is still young, but a few findings offer a credible sketch. When masochists were studied using brain imaging while viewing sadomasochistic content alongside painful stimulation, their brains responded differently from those of non-practitioners. Specifically, an area called the parietal operculum, which helps process touch and body awareness, showed heightened activity but reduced connectivity with the insula, a region involved in coding how unpleasant a sensation feels. In plain language, the brain appeared to register the pain signal while turning down the volume on the “this is bad” interpretation.6PubMed Central. Contextual modulation of pain in masochists: involvement of the parietal operculum and insula
A systematic review of the biology behind these practices identified several brain regions that work together during sadomasochistic experience: the parietal operculum and ventral striatum (tied to pleasure and reward), the somatosensory cortex (processing physical sensation), empathy-related circuits in the anterior insula and midcingulate cortex, and the left frontal cortex involved in social and sexual interactions.7The Journal of Sexual Medicine. The Biology of BDSM: A Systematic Review The picture that emerges is not of a broken pain system but of a brain that, in the right context, routes intense sensation through reward and bonding pathways instead of pure threat pathways.
One detail worth noting: when researchers tested masochists and controls outside of any sexual or sadomasochistic context, simply applying heat to the forearm in a lab, the two groups had nearly identical pain thresholds. Their spinal-cord reflex responses were the same too.8PubMed Central. Pain and masochistic behaviour: The role of descending modulation This strongly suggests that masochists are not numb to pain in everyday life. The difference shows up only when the psychological context, arousal, trust, anticipation, frames the sensation as something desired.
Hormones, Stress, and Bonding
The body’s chemical response during sadomasochistic encounters also points toward a bonding mechanism rather than a harm mechanism. A study measuring hormone levels during consensual scenes found that cortisol, the body’s primary stress hormone, rose significantly in participants who were on the receiving end (those being bound, receiving physical stimulation, or following orders). Participants on the giving end did not show the same cortisol spike. Among women in the receiving role, testosterone also increased during scenes.9PubMed. Hormonal changes and couple bonding in consensual sadomasochistic activity
That cortisol spike might sound alarming, but a temporary rise in cortisol is the same thing the body does during intense exercise, roller coasters, or even passionate argument. In combination with endorphins and oxytocin, both of which are released during intense physical and emotional experiences, it can produce the altered-consciousness state that practitioners often describe as “subspace” or a deep sense of closeness. A study of a large-scale ritual event involving temporary piercings and physical intensity found that participants experienced increased physiological stress alongside decreased psychological stress, greater feelings of closeness with others, and states described as spiritual or transformative.10PubMed. Extreme rituals in a BDSM context: the physiological and psychological effects of the ‘Dance of Souls’ The body’s stress system, paradoxically, can serve as an engine for euphoria and connection when the stressor is chosen, controlled, and shared.
Sadist, Masochist, Switch, and the Fluidity of Roles
Popular culture likes to sort sadomasochists into neat boxes: the dominant sadist on one side, the submissive masochist on the other. The reality is messier and more interesting. While research does find that men are more likely to identify with dominant or sadistic roles and women with submissive or masochistic ones, a substantial portion of practitioners identify as “switches,” meaning they move between both sides depending on their mood, their partner, or the specific scenario.11PubMed. BDSM Role Fluidity: A Mixed-Methods Approach to Investigating Switches Within Dominant/Submissive Binaries
Switches are particularly common among women and among queer and pansexual individuals, which has led some researchers to view switching as a way of disrupting traditional gendered power binaries rather than reinforcing them. Qualitative research on switches finds that their role fluidity is tied to a sense of personal identity: they describe the capacity to occupy both sides of a power exchange as core to who they are, not as indecisiveness. Some switches report experiencing different emotional and psychological states in each role, essentially accessing different parts of themselves.12Sexualities. “Switch it up”: A qualitative analysis of BDSM switches
This fluidity matters for understanding sadomasochism because it undermines the assumption that these desires are fixed in one direction. Many people who enjoy tying a partner up also want to be tied up, and many who enjoy delivering intense sensation also crave receiving it. The umbrella term “sadomasochist” captures this duality more accurately than either “sadist” or “masochist” alone.
Consent Frameworks and How the Community Self-Regulates
Because sadomasochistic activities involve sensations and power dynamics that could easily cause harm if done carelessly or without agreement, the community has developed its own ethical language. The most widely known phrase is “safe, sane, and consensual,” or SSC, which emerged in the 1980s as a way to distinguish consensual kink from abuse. Over time, alternatives such as “risk-aware consensual kink” (RACK) gained traction, acknowledging that some activities carry inherent risks that cannot be eliminated, only managed with clear communication.
Interestingly, a study of kinky gay and bisexual men who organized encounters through online platforms found that most participants were not actually familiar with the formal phrases like SSC or RACK. Instead, they had developed their own methods for negotiating risk and consent, primarily through extensive conversation before meeting. The researchers noted that in-depth online communication served as the main tool for establishing boundaries, rather than reliance on community catchphrases.13Journal of Positive Sexuality. Beyond Safe, Sane, and Consensual: Navigating Risk and Consent Online for Kinky Gay and Bisexual Men This suggests that the principles behind the slogans, explicit negotiation and mutual agreement, have filtered into practice more broadly than the slogans themselves.
Typical negotiation involves discussing hard limits (activities that are off the table completely), soft limits (activities someone is uncertain about), safe words or signals to stop, and aftercare, the period of emotional and physical tending that follows a scene. Aftercare is particularly important: as the cortisol and endorphin levels described earlier drop back to baseline, some people experience a vulnerability that experienced practitioners anticipate and plan for.
Stigma in Healthcare Settings
One of the more consequential challenges for sadomasochists is navigating the healthcare system. People who engage in kink can face health complications specific to their activities, such as rope marks, bruising, or nerve compression, but fear of judgment can keep them from seeking care or being honest with providers about how an injury occurred.14The Journal of Sexual Medicine. Fifty Shades of Stigma: Exploring the Health Care Experiences of Kink-Oriented Patients
The problem extends to mental health care. A team of 20 clinicians and researchers spent two years developing clinical practice guidelines for therapists working with kink-oriented clients, driven in part by evidence that many therapists either pathologize consensual kink or simply do not know how to address it competently. The guidelines emphasize that clinicians should not conflate consensual sadomasochism with abuse, should explore what these interests mean to the individual rather than assuming pathology, and should recognize their own biases before engaging with kink-related topics in therapy.15PubMed. Clinical Guidelines for Working with Clients Involved in Kink For someone seeking a therapist who will not treat their sexuality as a problem to solve, asking upfront about “kink-aware” or “kink-affirmative” credentials can save a great deal of frustration.
Why Context Explains What Pathology Cannot
The single most important thread running through the research is context. The same physical sensation, a sharp slap, pressure from a rope, a verbal command, registers as violation in one setting and as thrilling intimacy in another. The brain imaging research shows this is not just a matter of attitude: the neural processing genuinely changes depending on whether the person has chosen the experience, feels safe with the partner, and is sexually aroused. Outside that frame, masochists feel pain just like everyone else.
Evolutionary theorists have offered various explanations for why this capacity exists at all. One line of thinking connects sadomasochistic interest to broader human tendencies around ritualized pain and social bonding, noting that many cultures use controlled physical ordeals as a way to deepen group ties, mark transitions, or signal commitment. The psychophysiological stress response triggered by intense stimulation can, in the right conditions, strengthen emotional bonds and generate pleasure, an idea supported by hormonal data showing that consensual pain play activates both stress and reward pathways simultaneously.16PubMed Central. An Evolutionary Psychological Approach Toward BDSM Interest and Behavior These explanations remain speculative, but they help reframe sadomasochism as one expression of a much broader human relationship with intensity and vulnerability, rather than as a bizarre outlier.
Cultural Differences in How Sadomasochism Is Expressed
Sadomasochistic interests show up across cultures, but how people act on them varies. A large international survey comparing practitioners in North America, Europe, and Oceania found that Europeans tended to report an earlier age of first fantasizing about sadomasochistic themes, while North Americans were more likely to participate in organized public events such as play parties and club nights. The researchers attributed these differences partly to varying levels of religiosity and cultural stigma surrounding non-traditional sexual interests.17PubMed. BDSM in North America, Europe, and Oceania: A Large-Scale International Survey Gauging BDSM Interests and Activities
The digital landscape has also reshaped how sadomasochists find each other and express their identities. An ethnographic study of a Swedish kink platform found that online communities occupy a peculiar position: they are simultaneously marginalized (excluded from mainstream social media, subject to content moderation crackdowns) and seemingly mainstream (referenced constantly in popular culture). Members navigate a delicate balance between seeking visibility for acceptance and maintaining privacy for safety.18Sexualities. Digital kink obscurity: A sexual politics beyond visibility and comprehension This tension between increasing cultural awareness of kink and the ongoing need for discretion defines much of the modern sadomasochistic experience. For many people, the first encounter with the concept is fictional, through novels, films, or social media, but the lived practice is shaped far more by community norms, personal negotiation, and trust than by anything they saw on a screen.
