Stumpgasm. Noun. The physical and emotional sensation experienced at the peak of sexual excitation resulting from stimulation of a limb stump. 

Tim Steele, a film editor who claims that he had a three-year affair with Heather Mills before she broke it off for her relationship with Paul McCartney, claimed yesterday that Mills was sexually insatiable. She purportedly had a hoard of vibrators for when she was home alone and "a huge back massager that she plugged into the mains." But the most fascinating revelation Steele made was Mills' fondness for stumpgasms.

Film editor Steel also revealed Heather, who lost her left leg below the knee in a motorbike accident in 1993, went wild with pleasure when he massaged her amputated limb.

He said: "Heather has a very unusual erogenous zone - her stump. I used to massage one particular area and it gave her an orgasm."
