Emetophilia
（重定向自Roman Shower）
Emetophilia is a paraphilia in which an individual is sexually aroused by vomiting or observing others vomit, also referred to as a vomit fetish. Some emetophiles put emetophilia into practice by actually vomiting, especially on a partner. This practice is sometimes called a "Roman shower", after the commonly supposed belief in the frequent induction of vomiting at Roman feasts.
