I've just posted a reply to ID's 'What's your Fetish?' thread with regards to this. It happens to me quite a lot. Think about this, when a woman has multiple and successive orgasms it takes a lot of energy away from her. Although I love it, it does make me very tired afterwards and I have often passed out during and after. That is why trust is really the key issue here. There is a reason why us French call orgasms 'la petite morte' - the little death. It quite literally takes your breath away and as subwife said takes you into sub space *my happy place*
