1, abdominal friction. Before going to bed, put one hand on the lower abdomen under the navel, and the other hand on the lower abdomen and rub it slowly from left to right, taking the warmth of your abdomen as the degree.

2, groin massage. Before going to bed, put your hands on the groin (thigh root) on both sides, and gently massage with your palm obliquely for 36 times, several times a week, which has a certain effect on enhancing sexual desire and improving energy.

3. Knead the testicles. Rub your hands hot, first hold the testicle with your right hand so that the right testicle is on the rib surface of your thumb, forefinger and middle finger, then gently rub it and turn right for 30 ~ 50 times, with a slight feeling of soreness and no pain, and then gently rub it with your left hand as above. You can also use moxibustion, that is, tighten the scrotum with your hand first, fix the external kidney, put the palm of your other hand on the testis, and then gently rub it, taking the testicular fever as the degree. This method, also known as "taking kidney outside the capsule", has been highly praised by TCM health experts in past dynasties.
