By coming too hard etc. Any stomach cramps etc...?
The next morning I was pretty sore, but that was after a LOT of orgasms!
Bethany,
If you lose count, who gives a shit? Take a nap.
When using a Sybian I have experienced multiple orgasms for some minutes and almost passed out as the sensation was overwhelming. It was a deliberate decision of mine and afterward my pussy tingled and was so sensitive I couldn't touch it for ages. It was an amazing sensation but a bit dangerous taking myself to that stage.
My girl friend has barred me from doing that unless she is there with me - more to protect me from myself than for her own erotic experience of seeing me in that state.
After a string of orgasms my vaginawill go into this like sensory overload where any sensation is magnified by a million times and is real painful. I have to stop for a while and lay there eagle spread until the throbbing and shaking stops
