Emetophilia is a sexual fetish in which an individual is aroused by vomiting or observing others vomit. When emetophiles put emetophilia into practice by actually vomiting, especially on a partner, it is called a Roman shower, after the supposed frequent induction of vomiting at Roman feasts.
Some emetophiles find the act of vomiting arousing; for them, the sequence of "spasm, ejaculation, relief" in vomiting is erotically charged. Other emetophiles are aroused by seeing and/or hearing others vomit. Some desire a partner who will vomit on them, while others wish to induce vomiting in a partner, or even force them to vomit. (Wanting to be vomited on is probably related to a desire to be humiliated or degraded, while wanting to make someone else vomit may stem from a desire to humiliate or degrade the partner - see erotic humiliation.) Of course, most emetophiles have more than one of these desires, in various combinations.
An online site theorizes, "vomiting was probably something either arousing or frightening to emetophiles at some point ... it aroused powerful emotions, and the emetophile called upon these emotions for the purpose of sexual gratification." (Frequently Asked Questions about Vomiting) Often emetophobia can, paradoxically, lead to emetophilia, or even a mixture of the two in which a person is afraid to vomit, but aroused by witnessing someone else vomiting.
In some cases, emetophilia is directly related to vorarephilia. The emetophile fantasizes that he or she is consumed by the person who is vomiting, and imagines him/herself as covered by the contents of the person's stomach while within the stomach of the person who is the target of their fantasy.
