Kegel exercises are your friend.
The muscles you strengthen during Kegel exercise, the “PC” (pubococcygeus), are some of the muscles that contract during orgasm, so toning them enhances those sensations and makes it easier to reach climax. The most common kegel exercise is the Flutter routine. Squeeze and relax the PC muscle rapidly, in a pulsing motion. In the beginning aim for consistency of pulses, rather than speed; that will come with time and practice. Work up to 25 or 30 pulses. Kegels are well worth the effort. They’ll help you reach orgasm more easily and feel it more intensely. These 4 Kegel exercises are easy to do anywhere, anytime.
