CHICAGO (CBS) – What might seem like the gift that  keeps on giving to some has been a non-stop nightmare for a Wisconsin  man who suffers up to 100 unwanted orgasms every day. 
 “There’s nothing pleasurable about it, because even though it might  physically feel good, the whole time inside your mind, you’re completely  disgusted by what’s going on,” said Dale Decker, who suffers from  Persistent Genital Arousal Syndrome, an uncontrollable condition that  causes spontaneous and persistent orgasms unrelated to any physical  stimulus or feelings of sexual arousal.
 Barcroft Media reports Decker, 37, of Two Rivers, Wisconsin, is the  first man to speak publicly about the condition, which he said is  ruining his life.
 “Depending on where you’re at, if you’re in public, if you’re in  front of kids, if you’re around strangers, I mean it can make a person  break real fast,” he said. “When you’re on your knees at your father’s  funeral at his casket, and you’re saying goodbye to him, and then you  have nine orgasms right there while your whole family is standing behind  you, you never want to have another orgasm as long as you live. But you  know what? They just keep on coming.”
 He first began suffering from the condition in 2012, after slipping a  disk in his back while getting out of a chair. While on his way to the  hospital, he had five unwanted orgasms, and they’ve continued on a  regular basis ever since.

So there is a device - spinal cord stimulator - that is used to treat pain after failed spinal surgery (happens quite a bit). One of the unexpected adverse events of the device is spontaneous orgasm if the lead is in the "wrong" place on the spinal cord.
The company tried to start a trial to see if they could treat sexual dysfunction in women. It failed hopelessly and seems to only be the occasional complication of the procedure. Oddly patients were not particularly happy about the problem when they were wanting their pain treated!
