nono … im pretty sure i know whats going on. the same thing happened to me, and it might be the same thing for you guys. i’d say most of us do kegels right?? well when you do kegels during sex/masturbation it makes you cum faster. i even started to do them without realising it and it really started to piss me off. it even got to a point where it was hard not to kegel during masturbation and sometime i couldnt help it, it even got me to stop kegeling for awhile. however when i got back into it i started doing them again and just made sure that i relaxed a little more and was able to make sure i didnt kegel during sex/masturbation and it seemed to help. you can kegel inside her if you want, because it feels good for both you and your partner, however it will take time off how long you last. i believe that the only time a man should kegel during sex is right before you cum if you want to try the whole mult orgasm thing, which i find very useful :D . GL guys.
