讓我想到一種怪異的性癖好:
Emetophilia.
http://en.wikipedia.org/wiki/Emetophilia
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.
Emetophilia 大致就是說:
一個人必須要嘔吐或看到別人嘔吐,才會有性慾
