B: Qigong. Qigong has a good health care function, but unfortunately not everyone agrees with me. Not everyone has a basic knowledge of Qigong.
If you have qigong skills, no matter what genre you study, you must know that you are determined to stay in Dantian. When the abdomen sinks after quietness and the abdomen is full of fever, the penis will naturally erect, which is the so-called vigorous yang rising. At this time, it is necessary to maintain this erect state until the end of meditation. This is the most natural way to increase the blood flow of penis. Moreover, if you are a persistent qigong practitioner, qigong will bring you more benefits than that.
