Alternating hot and cold bath is an ancient exercise method to enhance male sexual function. The specific method is to soak the body in warm water in the bathtub first, then take it out of the bathtub after the body is fully warmed, smear the vagina with cold water for about 3 minutes, and then put it in the bathtub after the scrotum contracts, and repeat this for 3-5 times. If you can insist on alternating hot and cold baths every day, you can make men after middle age full of energy, enhance their sexual function and feel less tired. If you shower alternately with hot and cold water, the effect will not change.

When taking a bath, if you can use a shower head to pour warm water around the roots, it will also have a good effect on restoring the "energy" of the testicles. Because the erection of scrotum makes the ligaments and nerves supporting scrotum quite tired, and the longer the erection time, the more serious the fatigue. Warm water stimulation can accelerate blood circulation and restore testicular fatigue as soon as possible. Moreover, the shower is different from soaking in the bathtub, and the shower can produce concentrated heating stimulation on local acupuncture points. Of course, the water pressure in the shower is better.

Not only the scrotum root, but also the groin inside the thigh root is also an important stimulation site. Because the groin is the "communicating artery" that transports blood and nerves to the testicles, the blood circulation in the groin is very important for male sexual function. Stimulating the groin with warm water in the shower and stroking the groin with two fingers from top to bottom are also very beneficial to enhancing male sexual function.

In addition, there are some important acupoints in the lower abdomen, such as Guanyuan and Qihai. Stimulation with warm water can also enhance sexual function.
