When an orgasm has been achieved through sex, you can measure theta waves. These are also said to cause the "running high" feeling of euphoria experienced sometimes by marathon runners. If theta waves are taken as a criterion, the entire brain emits theta waves when women reach an orgasm that are close on 10 times stronger than when men climax. So, if theta waves are an indication of an orgasm's strength, then women experience an orgasm that is physically impossible for men to go through. Putting it a little crudely, if the intensity of a woman's orgasm was played through a man's brain, there's a danger that the shock to his system would kill him. That risk makes it impossible to experiment on a man at the moment. And men can never become women.
