Yes it happens to me frequently. I am a male but I'm EXTREMELY multi-orgasmic. So there are not a large percentage of us, but we are are not alone. I do experience very high numbers of brain melting super-intense multiple orgasms. Other times I may have an orgasm that does not stop but continues on and on, like one very very long orgasm- at any rate you may have trouble believing how long and how much I have orgasmed and climaxed in one sitting (non-stop for hours), so I think I can tell more on that later, or if anyone wants to know.
How long do your climaxes last? How many multiples do you achieve? As I said above, there are not many of us, so I think it's good if (people in our cool super-orgasm club, lol) can learn from each other.
Cheers,
David
