PC Muscle: Also known an the Pubococcygeus muscle, or one of the perineal muscles or Kegel muscles, this lies at the bottom of the pelvic girdle, and assists in control of urine flow, ejaculation in men, and childbirth in women. Exercising this muscle, known as Kegel exercises is good for men’s problems with urine retention, premature ejaculation, maintaining an erection, and can help with techniques such as the big draw.
You can feel this muscle tighten if you make it a point to tighten your anus, or pretend you can extend your erection if you are a man. You may see your penis move slightly in response.
