It definitely is a bit more complicated than just forcing the pee. That will never work to stop ejaculation. I have written detailed description months ago about this technique that I discovered by accident when a teen and it never fails if you follow rules perfectly. When you feel the inevitable orgasm about to happen, you must NEVER at this point try a kegel (unless you have mastered that technique of doing a dry orgasm) unless you have a sensationally powerful PE muscle. But if you do as other guys have stated bear down on your pelvic muscles as if you are trying to have a really good shit and are having trouble moving that turd out and hold it without letting up at all, then you have a perfect reverse kegel. You must do that bearing down nonstop until the urgency to cum passes before you relax. If you dare to do even a half ass kegel, you will cum immediately. And as you state, if you do a bunch of these you will have a spurting ejaculation that shock you. I used to do all night cams with guys and last for 7-9 hours with nonstop jerking and the final ejaculation would actually cause me to temporarily lose consciousness it would be so voluminous and so powerful. One time I was camming with a succession of 9 men who finally gave up waiting for me to cum and missed the final rocket launch. But again, you have to concentrate totally on engagement of the reverse kegel and of course must not be fucking during the engagement. You can suck tits or do some other servicing of your lady friend while the urge to cum passes.
