The muscles in a woman's pelvic floor region contract and release when she is having sex. According to Dr. Berman, the strength of these muscles contributes to the strength of the orgasm that a woman can have. "They also provide more friction against the G-spot if you use them during sex," Dr. Berman says.
As a woman ages or if she has a baby, the pelvic floor muscles can become loose. "Those are the muscles that you squeeze to stop the flow of urine. That's how you identify them—those are the Kegels," Dr. Berman says. "You have to strengthen them using those core muscle exercises and Kegel [exercises]. And if you have really strong Kegel muscle control, you should be able to squeeze your vagina ... in and up [and] in and back, and if you're really in control, side to side."
