Emetophilia
Emetophilia is a sexual fetish in which an individual is aroused by vomiting or observing others vomit. There are different levels of emetophilia. Most only discuss their vomiting and that of other people, as in Internet story boards. Many others collect pictures of people vomiting, and the most extreme emetophiles make these pictures and videos. When people carry emetophilia to an extreme by actually vomiting, especially on a partner, it is called a Roman shower, after the frequent induction of vomiting at Roman feasts.
An online site theorizes, "vomiting was probably something either arousing or frightening to [emetophilics] at some point ... it aroused powerful emotions, and the emetophilic later called upon these emotions for purpose of sexual gratification." ()
Emetophilia is closely related to emetophobia, the fear of vomiting, since some people have developed emetophilia as a result of emetophobia and many emetophilics, ironically, continue to fear vomiting themselves despite the amount of time they spend fantasizing about other people vomiting.
Emetophilics are most interested in the vomiting of people they are interested in sexually. (e.g., heterosexual men seek to learn about the vomiting of heterosexual women, etc.) Fantasizing about celebrities vomiting is commonplace, and is perhaps fueled by the bumper crop of vomit scenes in the movies and on TV in recent years.
