A British psychologist has recorded the case of so-called "eproctophilia" in a 22-year-old man from Illinois, America.
The man, who has been given the pseudonym Brad, states he enjoys both the "sound and the smell" of flatulence.
"At first, I didn't want to admit I was into his farting, but eventually I decided to experiment. I set up a bet at some point and intentionally lost, with the wager being the right to fart in the loser's face for a week. I continued to lose such bets once every few weeks for about two years."
