My father used to tell the story of when he worked as a jailer and there was a wino who had a boil-sucking fetish. He (the wino) would hang with the junkies in Chinatown on the west side, and when an abcess would inevitable occur, he would suck the puss from it for a bottle of booze. The hypes couldn't go to the Dr. for treatment (this was the late '50s), so just like a dog licking his wounds, the saliva and suction would heal. The part about him jerking off while he popped the head and got a dixie cup of junkie puss in his mouth....well, what can I say, except that I warned you it was a fetish story. My Dad first found out by walking in on it in a jail cell at bedcheck (picture Barney Fife catchin' Otis). The guy told his whole story, including his arrangement with the hypes. My Dad threw up, then beat the shit out of both of them. (this was the fifties, after all)
