Also try doing Kegel exercises daily, as your PC
muscle may be weak. This can contribute to the lack of sensation. The PC
muscle is the muscle that stretches from under your penis, up the shaft. Think of it as your "orgasm" muslce. It’s also related to the strength of your orgasmic contractions, so if it’s weak or flabby, your orgasms will be weak and flabby too. To strengthen your PC muscle, do Kegel exercises (named for the physician who discovered this clever little muscle).
