What is eproctophilia?
Eproctophilia is a paraphilia that involves sexual arousal from flatulence . This arousal can come from one or more aspects of flatulence including smell and sound, but it has also been known to be enjoyed as an element of domination and humiliation. For others, especially in relation to heterosexual males enjoying the flatulence of females, arousal with eproctophilia lies heavily in the taboo aspect of witnessing a societally forbidden activity .
How does eproctophilia work?
Many of those with eproctophilia enjoy experiencing or fantasizing the fetish in a romantic or consensual context, i.e. with a loving partner or trusted friend. There are those, however, that enjoy the context of masochism with flatulence, experiencing it or imagining it used as a kink element in a play scene of consensual non-consent.
To ponder why one would enjoy eproctophilia, the question of why anyone enjoys any paraphilia would need to be explored. In many self-reported cases, those with eproctophilia cite the exploration of poronographic material on the internet to be their inciting moment of exposure and realization of interest. For others, who noticed interests at a very young age, the paraphilia is believed to be linked to an exposing occurance in childhood .
Are there kinks related to eproctophilia?
As with all kinks, there's absolutely an element of personalization to how one would desire to experience them. In a general sense, eproctophilia will often accompany elements of facesitting, headscissors, breath play (smothering), and body worship. For some, there is an element of power exchange desired which is usually explored through verbal domination and objectification (human furniture) as well as aspects of humiliation play.
Despite the presumed intimacy of kink play aspects like facesitting, many of those with eproctophilia will often prefer the Dominant, or Top, be clothed; this is typically for those who derive arousal from the olfactory aspect of flatulence as the fabric tends to retain the aromas , however, clothing has been known to affect the auditory aspect as well.
Why have I never heard of eproctophilia and where can I learn more?
To date, there has only been a single officially published study of a person with eproctophilia ; as a result, we're left to analyze the fetish based mostly on personal accounts and anecdotes. Even within the kink community, eproctophilia is not widely known even though similar kink elements, like watersports and coprophilia, are somewhat more familiar to a broader segment of BDSM players.

Are there any notable references to eproctophilia in media?
In Stephen King's On Writing: A Memoir Of The Craft from 2000, the prolific author recalls an occurance from his youth:
Eula-Beulah was prone to farts -- the kind that are both loud and smelly. Sometimes when she was so afflicted, she would throw me on the couch, drop her wool-skirted butt on my face, and let loose. 'Pow!' she'd cry in high glee. It was like being buried in marshgas fireworks. I remember the dark, the sense that I was suffocating, and I remember laughing. Because, while what was happening was sort of horrible, it was also sort of funny. In many ways, Eulah-Beulah prepared me for literary criticism. After having a two-hundred-pound babysitter fart on your face and yell, Pow!, the Village Voice holds few terrors. 
In one of James Joyce's infamously dirty letters, dated December 8th, 1909, he makes colorful reference to flatulence (censored for language):
At every f--k I gave you your shameless tongue came bursting out through your lips and if a gave you a bigger stronger f--k than usual, fat dirty farts came spluttering out of your backside. You had an arse full of farts that night, darling, and I f--ked them out of you, big fat fellows, long windy ones, quick little merry cracks and a lot of tiny little naughty farties ending in a long gush from your hole. It is wonderful to f--k a farting woman when every f--k drives one out of her. I think I would know Nora's fart anywhere. I think I could pick hers out in a roomful of farting women. It is a rather girlish noise not like the wet windy fart which I imagine fat wives have. It is sudden and dry and dirty like what a bold girl would let off in fun in a school dormitory at night. I hope Nora will let off no end of her farts in my face so that I may know their smell also.
You say when I go back you will suck me off and you want me to lick your c--t, you little depraved blackguard. I hope you will surprise me some time when I am asleep dressed, steal over to me with a whore's glow in your slumberous eyes, gently undo button after button in the fly of my trousers and gently take out your lover's fat mickey, lap it up in your moist mouth and suck away at it till it gets fatter and stiffer and comes off in your mouth. Sometimes too I shall surprise you asleep, lift up your skirts and open your drawers gently, then lie down gently by you and begin to lick lazily round your bush. You will begin to stir uneasily then I will lick the lips of my darling's c--t. You will begin to groan and grunt and sigh and fart with lust in your sleep. Then I will lick up faster and faster like a ravenous dog until your c--t is a mass of slime and your body wriggling wildly.
Goodnight, my little farting Nora, my dirty little f--kbird! There is one lovely word, darling, you have underlined to make me pull myself off better. Write me more about that and yourself, sweetly, dirtier, dirtier. 
Though not necessarily a sexual affinity, Benjamin Franklin wrote a letter to the Royal Academy about the importance of farting:
It is universally well known, That in digesting our common Food, there is created or produced in the Bowels of human Creatures, a great Quantity of Wind.
That the permitting this Air to escape and mix with the Atmosphere, is usually offensive to the Company, from the fetid Smell that accompanies it.
That all well-bred People therefore, to avoid giving such Offence, forcibly restrain the Efforts of Nature to discharge that Wind.
That so retain’d contrary to Nature, it not only gives frequently great present Pain, but occasions future Diseases, such as habitual Cholics, Ruptures, Tympanies, &c. often destructive of the Constitution, & sometimes of Life itself.
Were it not for the odiously offensive Smell accompanying such Escapes, polite People would probably be under no more Restraint in discharging such Wind in Company, than they are in spitting, or in blowing their Noses.
My Prize Question therefore should be, To discover some Drug wholesome & not disagreable, to be mix’d with our common Food, or Sauces, that shall render the natural Discharges of Wind from our Bodies, not only inoffensive, but agreable as Perfumes. 
The oldest documented reference to farts as humor is seen in Japanese scrolls as noted on Wikipedia regarding He-gassen:
He-Gassen (Japanese: 屁合戦, literally: "Fart competitions"), or Houhi-Gassen (放屁合戦), are titles given to a Japanese art scroll, created during the Edo period (1603–1868) by an unknown artist or several unknown artists depicting flatulence humor.
He-Gassen is a subject occasionally depicted in Japanese art, first attested at the end of the Heian Period (794–1185). Toba Sōjō (1053–1140), in addition to his famous Scrolls of Frolicking Animals, is also mentioned as having painted scrolls on themes such as "Phallic Contest" and "He-gassen."
