That'd be like saying you can watch a movie with your eyes closed...
Isn't the very definition of cllmax - peak of sexual arousal including ejaculation? And if there is no ejaculation - how can we even call it an "cllmax"?
"Multi cllmaxic man" sounds like a good way to make money selling tons of books. Heck, I may even include it in my sexual fantasies, but i don't expect to become multi-cllmaxic any time soon. (although I wouldn't object) ;-)
