The pelvic muscle at the root of penis is called male coitus muscle, in which pubic coccyx muscle plays a major role. Strengthening the muscles in these parts can increase the blood supply to the whole pelvis and penis.

Theoretically speaking, this situation can promote erection, increase the pleasure during orgasm and help patients control ejaculation, because one of the characteristics of male orgasm is that these muscles contract regularly. The method of exercising male sexual intercourse muscles is also called Kaigl exercise.

Extended data:

The first step in practicing pelvic rotation is to stand on the ground, with your feet about 30 cm apart, your knees slightly bent, your hips tightened, and your arms hanging at your sides. Relax all over, move the pelvis up and forward very slowly, and then turn right until you can't turn right any more. Put your body weight on your right foot, put your pelvis back in its original position (hips are raised), then turn your pelvis to the far left, and your body weight falls on your left foot.

Secondly, let the pelvis go up, contract the buttocks, and then rotate to the right foot, so it doesn't look easy. So we should do it slowly from the beginning, make an action and think about it. After practicing the rotation for ten times, rotate the pelvis in the opposite direction. Rotate ten times in each direction until you can rotate twenty times. Some women say it's much easier to practice with music.
