The specific practice is that when the sexual excitement is low, the penis will not be inserted into the vagina, the other parts of the body will be in contact with the woman as much as possible, and the frequency and amplitude of penis pumping will be accelerated, when the sexual excitement is too high, the penis pumping will be reduced or the vagina will be withdrawn for a short rest. This can improve the response threshold of the ejaculation center. In the whole training process, the attention to sex can be adjusted by alternate methods of concentration and dispersion. For patients with serious premature ejaculation, such as those who ejaculate when they have physical contact with women such as hugging and kissing, those whose penis just touches their labia, and those whose ejaculation and erection are even basically synchronized, the penis squeezing method can be used. The penis pinching method was proposed by Masters and Johnson in the United States, and the specific practice is: the man takes the supine position, the woman sits on the man’s side or between the man’s legs, and gently stimulates the penis with her hand to make it erect, and after erection, continues to stimulate until the man’s orgasm, at which time the man signals the woman to stop stimulating or the woman pinches the coronal groove of the penis with her fingers to make the man feel slight pain, and the penis can gradually Weakness, followed by a second round of female stimulation, so repeated training so that the male penis to stimulate the adaptation gradually enhanced, the ejaculation center response threshold is increased. The majority of patients can receive significant results by insisting on 1-2 weeks of training. The basic principle of the above treatment for premature ejaculation is to improve the ejaculation threshold through training, so as to prolong and control the time of ejaculation.
