Multiple orgasms aren’t always as wonderful as some people think. One of the problems with multiple orgasms is that after having many small orgasms the woman is left unsatisfied, while women who have one very strong orgasm are left completely satisfied, at least for a time. Now I don’t know enough about your situation to say exactly what type of orgasms you are having, and I don’t really know of a way for you to change from multiple orgasms to stronger, more satisfying single ones, but perhaps you could try to make a transition to this type. See if by stopping yourself from having a “little” orgasm, so that your arousal builds and builds until you can’t stand it anymore you can create a situation where you get one big, completely satisfying orgasm. Again, I don’t have any particular techniques to offer you, but perhaps you can figure something out. And let me know what happens. Good luck.
