Vomit Fetish

Emetophilia (also called emetolagnia, and known in slang as a "Roman shower") is a sexual interest in the act of vomiting or in vomit itself: one's own, a partner's, or the sight, sound, or smell of another person being sick. It is grouped with the excretory bodily-function interests and is documented in only a handful of clinical case reports alongside reference catalogues of paraphilias and small online communities. This article covers the term's origins, the sparse clinical record, the proposed psychology, its rarity, and above all its substantial health and consent considerations. The treatment is strictly descriptive, with no instructional content.

Examples

What the term covers. The sparse literature distinguishes three orientations, and the entry covers all of them: arousal at being sick oneself, at being vomited on — the sense the slang "Roman shower" carries — and at watching or hearing another person be sick. The two published case reports happen to sit at opposite poles of that range. Most reported expression is observational or imaginative, through video, audio and description, rather than participatory.

What the term does not cover. Emetophobia, the fear of vomiting, is the opposite condition and a far better-known one; the two words are routinely mistaken for each other. Scat fetish and watersports are the other excretory interests and fart fetish the flatulence one, all of them sitting under the broader body fluid heading. Wet and messy play produces mess from food, mud and slime with no bodily material involved, and salirophilia is about soiling a partner's appearance rather than about sickness. Where the appeal is the loss of dignity rather than the substance, humiliation play or degradation describe it more accurately. Recurrent self-induced vomiting outside any erotic context is an eating-disorder question and a medical one, not this.

How the word is used. Emetophilia and the variant emetolagnia are catalogue terms, found in paraphilia lists and in the two case reports, and in neither the DSM-5-TR nor the ICD-11. "Roman shower" is the only form most people have heard, and, as the history below sets out, the image of Roman banqueters purging to keep eating that gives the phrase its name is a modern myth rather than a documented practice.

History & origins

Terminology

The precise coinage of emetophilia is not well documented, and it is best understood as a modern, finer-grained label rather than a classical clinical term. Its roots are plain: Greek emesis / emetikos ("vomiting; that which induces vomiting") combined with -philia ("love of, affinity for"), with the variant emetolagnia using -lagnia ("lust"). The interest belongs to the broad nineteenth-century project of naming sexual variations exemplified by Richard von Krafft-Ebing's Psychopathia Sexualis (1886), which established the practice of cataloguing such interests with Latin and Greek labels. Emetophilia is a later addition to that lineage and was not a term Krafft-Ebing used; today it survives chiefly in descriptive references such as Wikipedia's Emetophilia article rather than in primary research.

Clinical documentation

The formal literature on erotic vomiting is very small, amounting to two case reports separated by forty years. The first systematic account was Robert J. Stoller's "Erotic Vomiting" (1982) in Archives of Sexual Behavior, which described three women for whom self-induced vomiting was bound up with sexual arousal, a pattern Stoller presented as previously unreported. The second appeared decades later: Hasanuddin and Effendy (2022), writing in the Open Access Macedonian Journal of Medical Sciences, reported a 29-year-old woman who had experienced arousal from watching others vomit since childhood. Because it caused her no marked distress or impairment, the authors classified it as a paraphilic interest rather than a paraphilic disorder. Between them the two reports sketch the interest's poles (the actor who is sick and the observer of another's sickness) but the record is far too thin to support any general claim about cause or prevalence.

The "Roman shower" misnomer

The popular epithet "Roman shower", slang for being vomited on in a sexual context, is a modern coinage that alludes to the belief that ancient Romans habitually induced vomiting at feasts so they could keep eating. Historians regard this as a myth: a vomitorium was in fact an amphitheatre passage that "spewed" crowds out to their seats, not a purging room, and the gluttony trope appears to be a 19th- and 20th-century misreading of satirical Roman sources. The term reflects cultural folklore, not any documented historical practice.

Diagnostic status

Neither the DSM-5-TR nor the ICD-11 lists emetophilia as a discrete disorder. Like most uncommon paraphilias, it would be captured only under a broad "other specified paraphilic disorder" heading, and only where it causes the person marked distress or impairment, or where it involves a non-consenting party. A consensual private interest that causes no harm is not, in itself, a clinical diagnosis: a distinction the 2022 case report turns on directly.

In practice

Reported manifestations are uncommon and, in described accounts, are typically situated within established consensual contexts. The focus may attach to the act of being sick, to associated sensations, to the visceral sight or sound, or to dynamics of vulnerability and loss of control, the last linking it conceptually to humiliation and power-exchange play. Consistent with the educational and non-explicit purpose of this entry, no descriptions of technique are provided.

Psychology

What causes it?

No specific cause is established. Proposed frameworks are drawn from general models of paraphilic interest rather than from dedicated study of emetophilia, of which there is essentially none. They include associative learning (an arousal response conditioned to an unusual cue), the eroticisation of taboo and of loss of bodily control, and links to humiliation or dominance and submission dynamics that recur across the excretory interests. Low disgust sensitivity is also cited as a plausible contributing trait, since interest in body-fluid stimuli runs counter to the strong disgust response most people have. The evidence base is thin and largely inferential: Stoller's and the 2022 report's single-case observations cannot establish a general mechanism.

Prevalence & culture

How common is it?

Emetophilia has very low prevalence and little academic study beyond cataloguing, so any estimate is highly uncertain and leans on niche community size. The best available proxy is the broader finding from Scorolli et al. (2007), a large analysis of online fetish communities, that body-fluid and excretory interests collectively form only a small share of fetishes overall, consistent with emetophilia being a rare niche within that already-small group. Community presence on platforms such as FetLife is correspondingly modest. Mainstream cultural visibility is minimal and largely limited to the interest's deployment as a shock or taboo reference.

Safety, consent & law

Deliberately inducing vomiting carries real and serious health risks. Repeated self-induced vomiting produces the same medical harms seen in bulimia nervosa: erosion of tooth enamel by stomach acid, tears of the esophagus, electrolyte and fluid imbalance, and the danger of choking or aspiration.

Vomit is also infectious material. Stomach contents can carry norovirus — which spreads readily by contact and through the fine particles vomiting expels, and which persists stubbornly on surfaces — along with hepatitis A and the ordinary run of gastrointestinal bacteria, any of which can pass to another person by way of the mouth, the eyes, the hands or broken skin. Stomach acid is corrosive to skin, eyes and dental enamel on contact, and aspirating vomit into the airway is a medical emergency whose likelihood rises sharply if anyone involved has been drinking or is not fully alert. For these reasons the interest is flagged extreme-risk.

Any expression requires fully informed adult consent and caution, and recurrent self-induced vomiting can additionally signal an eating disorder that warrants medical attention. The interest would warrant clinical attention where it causes distress or impairment, and it is illegal where it involves a non-consenting person, a minor, or coercion.
