I have mentioned this to other guys who have also rarely experienced this very unusual orgasm that convulses parts of the body totally untouched by regular orgasms. You have to have a fairly sensitive cockhead to jerk off a flaccid cock fast enough to reach orgasm before it gains the upper hand and stiffens on you. Think of anything at all to keep your mind off of your impending erection and pump like shit something like a fucking rabbit. When while still soft and just above to cum, probe the index finger deep into base of your pee channel to cut off the ejaculation for about 5 seconds or so then let it rip. There will be a rush of cum but absolutely no orgasm at all for about 3-5 seconds then suddenly your whole body will be grabbed in a feeling like nothing you have ever experienced, a wave of pleasure that washes over the whole body. It is not exactly better than a regular orgasm, but totally different and gorgeous feeling. I never could do the "stop the cum" action when masturbating my erect cock, so apparently it only works on a marshmallow cock.
