I read a medical textbook (neurology) that said in some people, the act of orgasm can be so intense and powerful that the person can literally faint from the stimulation.Its not a common phenomenon but it does happen.  So for the ladies.....have you ever had such a mind blowing orgasm that it happened to you?  Or for that matter, did you ever provide one so intense to a client that he actually passed out from it?  Let's hear your story....what did you do?
