I don't have multiples often. I need to have a quick rest inbetween. It just feels sore if not! MY boyfriend insists on the "one is not enough" theory as well...so I never get to rest too long.

And Cobalt...I USED to have multiples all the time. I don't think its a matter of "toughening up" anything, IMHO. But once I discovered G-spot orgasms that stopped. One mind blowing orgasm is enough! i'd rather have one earth-shaking, mind-blowing, screaming orgasm than multiples anyday!
