Male orgasms are much  more intense if you masturbate and stop right before ejaculating for a few times before actually doing it.  Why does this method work?

Most nerves use something called cascades (proteins use it too but proteins use hormones instead of cations). The cascade is basically when something small causes large changes and an increasing avalanche effect/chain reaction (this is why you can't stop an orgasm once you hit the vinegar strokes). If the levels hit a certain point, the cascade will be triggered and the final effect can be much stronger than what caused it, but if the event is even one atom off from causing the cascade, nothing will happen. When your penis is stimulated, the molecules responsible for causing the ejaculation/orgasm begin production or transportation to the nerves associated with the action. The closer towards orgasm the nerves get, the higher the concentration of these molecules becomes. If the cascade is not triggered, the molecules won't do anything and continue to build up (arguably the chemical basis for "blue balls" though psychological evolution plays its part too). When the orgasm actually happens after being pushed to the edge multiple times, not only are the nerves primed for a strong response, but the molecules that make it happen are in such high concentration that the effect of the orgasm seems multiplied many times over. Also this probably has something to do with desensitization but that's to do more with the relative feeling rather than what causes the differences.
