what's more,

nearly 200 of Dr. Hartman and Dr. Fithian's male patients who practiced Kegels learned to delay ejaculation, enabling them to prolong sex to their own and their partner's satisfaction. And most surprising, 10 percent of these men were eventually able to have multiple orgasms--that is, two or more climaxes during a single act of intercourse before ejaculating. (Orgasm and ejaculation don't always occur simultaneously in men.)
