What Is Sadomasochism? The Four Distinct Things the Word Means

Before walking each one, name them at once:

Window 1 — standalone sadism. The interest in giving pain or controlling discomfort, considered on its own. A person can be sadistically inclined without ever pairing with a masochist; not all sadism gets expressed in coupled scenes.

Window 2 — standalone masochism.The interest in receiving sensation, control, or what Krafft-Ebing originally called “subjection,” considered on its own. Masochists outnumber sadists in most community surveys and many of them play with sensation tops who don’t identify as sadistic.

Window 3 — the coupled SM scene.When sadism and masochism are paired into a negotiated dynamic with a top giving and a bottom receiving, this is the SM scene. Most kink-community writing uses “SM” for this window specifically.

Window 4 — the clinical / forensic use. DSM-5 (United States) and ICD-11 (international) both list paraphilic disorders that use the words “sadism” and “masochism.” They refer to a different referent than windows 1–3 do, and conflating them with the kink is the single most consequential reading error this article exists to correct.

These four windows are real. The article’s job is just to keep them open separately rather than letting them collapse into a single blurred meaning.

Sadism, in the kink sense, is the recurrent erotic interest in giving another person pain, discomfort, or controlled suffering — with their consent. It is the inverse of masochism, but it is also a standalone identity that doesn’t require pairing.

The reason this is the most under-served meaning on the SERP is that almost every existing piece on “sadomasochism” collapses sadism into the coupled SM dynamic or jumps straight to the disorder. But many practicing sadists are top-only and never want to receive pain themselves. Their interest is in giving, in calibrating impact, in attention to the other person’s response, in authorship of the scene. That experience does not require a masochist counterpart to be coherent — it requires a partner who consents to receive the play, which is not the same thing.

The Hébert & Weaver studies (2014, 2015) documented dominants and submissives as measurably distinct populations with different personality profiles, distinct self-described benefits, and distinct challenges. The empirical takeaway is that “sadomasochism” implies a paired symmetry that the practitioner literature doesn’t support. Standalone sadism is its own thing.

One distinction the article will not develop in depth but will name: there is a separate construct in personality psychology called everyday sadism, measured by scales like the Comprehensive Assessment of Sadistic Tendencies (CAST), which captures non-sexual cruelty traits. The two constructs — kink-sadism and everyday-sadism — overlap at the extremes but are not the same thing, and most BDSM sadists do not show elevated everyday-sadism scores. For the kink identity question specifically, see am I a sadist, and for the closely-related-but-distinct “is the top always a sadist” question, see sadist vs dom.

Masochism in the kink sense is usually defined as the recurrent erotic interest in receiving sensation, pain, or control, with consent. The standard pop framing makes it primarily a pain orientation. The standard pop framing is half-wrong, and the half it gets wrong matters.

When Richard von Krafft-Ebing coined the term in Psychopathia Sexualis in 1886, he defined masochism “entirely in terms of control”: the masochist desires “to be completely and unconditionally subject to the will” of another. Pain wasn’t the constitutive feature for him; subjection was. Pain was one common medium for that subjection, but not the definition.

This matters because most contemporary self-identifying masochists, when asked what they actually want, describe something closer to Krafft-Ebing’s 1886 definition than to the modern pain-only framing. The community vocabulary already corrects for this: many masochists call themselves sensation-seekersor talk about being “in the headspace, not the hit.” The pain-pig and painslut identities exist as in-scene labels people claim for themselves, but they don’t exhaust the masochist population, and they don’t explain why a given masochist might love bondage and fall asleep under a heavy blanket but actively dislike being struck.

Standalone masochism, like standalone sadism, exists as its own identity. Many masochists play with sensation tops— partners who enjoy delivering sensation but don’t identify as sadistic at all. The top in such a scene isn’t aroused by the other’s suffering; they’re aroused by the other’s enjoyment of the sensation, which is structurally a different kink. For the identity question, see am I a masochist.

When community writers say “SM,” they almost always mean the coupled scene: a sadist or sadistic top paired with a masochist or sensation bottom, in a negotiated dynamic. This is the most familiar window for kink-curious readers and the one the practitioner literature has the most to say about.

BDSM-related interest in the general population isn’t niche. Holvoet et al. (2017) surveyed a representative Belgian sample of 1,027 adults and found that nearly half reported having performed at least one BDSM-related activity, around a fifth reported related fantasies, and roughly one in thirteen self-identified as a BDSM practitioner. The authors’ own conclusion, verbatim: “There is a high level of interest in BDSM in the general population, which strongly argues against stigmatization and pathologic characterization of these interests.”

Inside the SM scene specifically, the most useful internal distinction is sensation play vs heavy SM. Sensation play (ice, wax, pinwheel, gentle impact, novel textures) is about expanding the sensory palette. Heavy SM (canes, single-tails, intense impact, edge play) is about intensity for its own sake or for the masochist’s sake. Both are SM, but they ask different things of the negotiation, the partner skill, and the aftercare. Most heavy-SM events have stricter consent screening than general kink events — a community-side acknowledgment that the intensity step matters.

Switches exist as a third recognized identity — people who alternate between top and bottom, sadist and masochist, within a partnership or across partners. They are a real and stable subset of the community, not a transitional state. For the switch identity specifically, see am I a switch. For the coupled-but-not-symmetric question of how SM roles interact with the broader BDSM frame, see what is BDSM and sub vs bottom.

This is the load-bearing window — the one that does the most work the SERP keeps failing at — so it deserves the most precision.

DSM-5 (American Psychiatric Association, 2013) does not list “sadomasochism” as a coupled diagnostic category. It lists two separate paraphilic disorders: Sexual Sadism Disorder (302.84 / F65.52) and Sexual Masochism Disorder(302.83 / F65.51). These have been separate categories since DSM-I (sadism, 1952) and DSM-II (masochism, 1968) respectively. The coupled clinical term “sadomasochism” survives in some older European writing and forensic contexts, but it is not current DSM nomenclature.

DSM-5 makes a deliberate and crucial separation between a paraphilia(an unusual sexual interest, present in a person’s erotic life) and a paraphilic disorder (the same interest plus a distress / impairment criterion, or in the sadism case, the additional possibility of acting on it with a non-consenting person). For Sexual Sadism Disorder, the diagnostic line requires either acting on the urges with a non-consenting person OR clinically significant distress or impairment from the urges. For Sexual Masochism Disorder, only the distress / impairment criterion applies, since by definition the masochist is the one receiving consensually.

The practical consequence: a person can have sadistic or masochistic interests their entire life and never meet diagnostic criteria. Consensual BDSM is explicitly excluded from both diagnoses.

ICD-11 (World Health Organization, June 2018) went further. It removed sadomasochism, fetishism, and fetishistic transvestism as psychiatric diagnoses entirely, retaining only Coercive Sexual Sadism Disorder (6D33) for the non-consenting forensic case. The international clinical consensus, in other words, is that consensual sadomasochism is not a disorder at all and doesn’t warrant a diagnostic category.

What this means for reading any piece that uses “sadism” or “sadomasochism” in a clinical or forensic context: ask whether the writer is naming a paraphilia (an interest) or a paraphilic disorder (a clinical condition), and whether the case under discussion involves a non-consenting person. If both answers point to consensual play, the writer is in the wrong window and probably means SM in the community sense (window 3) but reached for the formal vocabulary. For related ground, see is BDSM abuse? and kink vs fetish.

Krafft-Ebing coined “sadism” (after the Marquis de Sade) and “masochism” (after the Austrian writer Leopold von Sacher-Masoch, who publicly objected to having his name used) as two separateclinical terms in 1886. The English coupled term “sadomasochism” is first documented around 1919, a generation later, and was a clinical convenience that smoothed two distinct phenomena into a single label.

That historical fact has structural consequences. The coupled term implies a paired symmetry between giving and receiving that the original 1886 vocabulary did not assert and that modern practice does not consistently show. A sadist with a non-masochistic submissive who’s into power exchange but doesn’t want pain is a real and common configuration; the coupled framing erases it. A masochist with a sensation top who isn’t sadism-coded at all is another real configuration; the coupled framing erases that too. The four-windows structure of this article matches the structure of the actual phenomenon better than the single coupled term does.

The most useful single take-away from this article is a register-detection habit. When you encounter “sadomasochism” or its components in any piece of writing, identify which register the writer is in:

With the register pinned, you can usually tell which of the four windows the writer is operating in: standalone sadism (window 1), standalone masochism (window 2), the coupled SM scene (window 3), or the clinical disorder (window 4). And with the window pinned, the writer’s claims become legible — or, more often, the writer’s sliding between windows becomes visible, which is itself useful information about what to trust in the piece.
