My record would be about seven feet, and that was as a happy ending to an erotic massage where the energy was building for almost two hours, including edging. If I edge on my own for about half an hour , I shoot about four feet. Yesterday, I was doing a quickie, but having watched some porn the hour preceding, was pretty lubed and primed, so that one struck my chest with full force. But ordinarily, just grabbing a quickie usually just yields a shot/ dribble of a few inches. For me its directly proportional to how worked up I am, and how long I have been delaying.
