Kegels are very good things. But in women, they don't control orgasms as much as they strengthen the underlying musculature that supports the reproductive system, which can make orgasms stronger and more powerful. They also are very beneficial in helping women prepare for--and recover from--pregnancy and childbirth. They're good exercises to do during youth and middle age to make sex better, and as we age, they're good exercises to do to help strengthen the foundation muscles and prevent bladder leakage.
