Make a pact with yourself that your next orgasm will be from intercourse. No matter what. It may take a few (or many) tries, but after much frustration, you will get there. It really is no more that re-training yourself.

You could try building up with a "private party" until you are an 8 or so on a scale of 10..... then switch to intercourse.

That is how I learned to have g-spot orgasms. I wasn't allowed to have clitoral ones until I figured it out. And it worked.

Good luck!!
