Masturbation

Masturbation, clinically termed autoeroticism, is the self-stimulation of one's own body for sexual pleasure. As a catalogued interest the term denotes a focus on solo activity as a meaningful or even preferred mode of sexual expression, rather than merely a substitute for partnered contact. For the overwhelming majority of people it is simply a normal, healthy component of their sexuality; for some it is a particular emphasis, valued for autonomy, control over pace and fantasy, and freedom from the negotiation that partnered sex involves. This article covers the term's turbulent history, how the interest is expressed, its psychology, and its remarkably high prevalence.

Examples

What the term covers. As a catalog entry this indexes an emphasis, not a technique. It covers people for whom solo activity is a settled and valued part of sexual life alongside an active partnered one; people for whom the appeal is control of pace, privacy and fantasy rather than the absence of a partner; people who build routines, media or aids around it; and people for whom it is simply unremarkable background. Mutual masturbation — partners stimulating themselves alongside or for one another — is autoerotic in method but partnered in setting, and sits inside the same territory.

What it does not cover. Several adjacent entries name things layered on top of solo activity rather than synonyms for it. Edging is deliberately delaying climax; gooning is the prolonged, trance-like state built on edging; jerk-off instruction adds a directing partner; orgasm denial is a power-exchange dynamic in which someone else holds the permission. A handjob is the partnered case — the same physical activity performed by someone else, a social distinction rather than a physical one. Mirror and recording interests describe what accompanies the act rather than the act. Compulsive sexual behaviour is a separate clinical matter defined by distress and impairment, not by how often someone masturbates.

How the word is used. Masturbation is both the plain-English and the clinical term, which is unusual in this catalog; autoeroticism is the formal synonym used in psychiatry and onanism the dated religious-moral one, now archaic outside historical writing. Neither DSM-5-TR nor ICD-11 lists it as a disorder or a paraphilia — the diagnostic manuals dropped it generations ago, and modern clinical writing treats it as a baseline of ordinary sexual behaviour rather than as anything requiring explanation.

History & origins

The behaviour itself is as old as humanity and appears in art and texts from antiquity; what has a real history is society's attitude toward it, which swung from indifference, to moral panic, to medical normalisation.

Etymology and early framing

• The English word masturbation entered the language around 1711 (with the earlier form mastupration attested in the 1620s), derived from Modern Latin masturbari: most likely an alteration of manstuprare, combining manus ("hand") and stuprare ("to defile"), with influence from turbare ("to disturb"); a minority view derives the first element from an unattested mazdo- ("penis").
• The competing term onanism (from 1727) takes its name from the biblical figure Onan and framed the act in explicitly religious-moral terms.

The long anti-masturbation panic

• c. 1716: the anonymous London pamphlet Onania, or the Heinous Sin of Self-Pollution recast the practice as a grave bodily and moral danger, igniting a wave of anxiety.
• 1760: the Swiss physician Samuel-Auguste Tissot published L'Onanisme, an influential medical treatise arguing that loss of semen caused "a perceptible reduction of strength, of memory and even of reason." Tissot's disease model dominated Euro-American medicine for roughly two centuries.
• 19th century: Victorian medicine pathologised "onanism" intensely, blaming it for insanity, blindness and a catalogue of ailments; Richard von Krafft-Ebing's Psychopathia Sexualis (1886) still treated excessive masturbation as pathological.

Normalisation in the modern era

• 1897: Havelock Ellis, in his Studies in the Psychology of Sex, concluded that moderate masturbation in healthy individuals produced no seriously harmful results, beginning the scientific rehabilitation of the behaviour.
• 1948 & 1953: the large-scale Kinsey Reports documented that masturbation was one of the most common of all human sexual outlets, in Kinsey's data the great majority of men and a clear majority of women reported having masturbated, decisively undermining the disease model with statistics.
• 1968 / 1972: masturbation was dropped from the DSM-II lineage of disorders and the American Medical Association affirmed it as a normal behaviour, completing the shift from sin to symptom to ordinary human sexuality.

In practice

The interest is expressed through private self-pleasure, frequently paired with fantasy, erotic media, or favoured routines and aids. Some people integrate it with adjacent interests such as fantasy scenarios, sensory preferences, mirrors, or consensual recording, while others keep it deliberately simple and self-contained. As a clinical, non-explicit reference matter the catalogue notes the focus on solo activity, not technique.

Psychology

Is masturbation normal?

Yes. Clinicians regard solo sexuality as a healthy, developmentally normal behaviour across the lifespan, not a sign of dysfunction. Solo sexuality is associated with self-exploration, stress relief, easier sleep onset, and bodily familiarity. A strong preference for it can reflect temperament, life circumstances, relationship status, or simply individual taste, and is not in itself a sign of dysfunction. The modern clinical literature explicitly treats common solo activity as normative rather than rare, in line with framings such as Joyal, Cossette & Lapierre (2015).

Prevalence & culture

How common is masturbation?

Survey research consistently ranks masturbation among the most prevalent of all human sexual behaviours. In Britain's National Surveys of Sexual Attitudes and Lifestyles (Natsal), reported masturbation in the past month rose from 73.4% to 77.5% in men and 37.0% to 40.3% in women between Natsal-2 (1999–2001) and Natsal-3 (2010–12), per Fischer and colleagues' published analysis (Journal of Sex Research, 2025). US lifetime figures are higher still: large majorities of adults of every gender report having masturbated. This places the interest near the very top of the prevalence scale relative to most catalogue entries. Cultural and religious attitudes still vary widely, but the behaviour itself is essentially universal and increasingly discussed openly in mainstream health media, as reflected in lay surveys of common sexual interests.

Safety, consent & law

The interest is entirely benign, private, and consensual by nature, with no inherent safety or legal concerns. Clinical attention arises only in the uncommon case where the behaviour becomes genuinely compulsive and distressing to the individual or materially interferes with daily functioning, a pattern addressed under compulsive sexual behaviour rather than as a property of masturbation itself.
