Klismaphilia is a glamorous Greek word that means "arousal by enemas." If you're not familiar, an enema is a medical device that squirts water slightly warmer than body temperature into your anus. It's used by hospitals to relieve people of constipation or to prep for certain medical procedures. (Not quite as glamorous as the Greek word makes it sound.) This particular kink generally refers to receiving pleasure from receiving an enema, although there are those who get off on administering enemas as well. The anus is an erogenous zone, after all, which helps explain why kinky folks have been using enemas for pleasure forever. This kink can also be quite practical—it's a way to clean and prep the rectum for anal sex.
