"a non-ejaculatory orgasm"!? That sounds interesting, I did at some points reach an orgasm but managed to keep it inside (not sure if that is what you mean) that was so hard to do. Because I did not want to cum for some reason....wanted to jerk longer, or a restroom at work and didnt want to make a mess. But that did not always work that well, due to that the friction of whatever the cock too sensitive. BUt when that worked, the actual release was indeed it seemed quite intense, hurfull(in a good way) to the balls even at times. Maybe this is what you mean by that.
