Glans desensitization training requires a scientific method, under the guidance of a doctor through the James Seaman method, pulling the scrotum method, penis squeeze method and so on. 1. James Seaman method, the specific operation method is to stimulate the penis to reach ejaculation, and then stop stimulation, until the excitement of the climax subsides, and then stimulate the penis. This is repeated many times until the man can tolerate a lot of stimulation without ejaculation. This method can increase the patient’s ability to withstand stimulation, so that he can quickly tolerate continuous stimulation without the need for intermittent stimulation. 2. Pulling the scrotum method, studies have found that when sexual excitement is high and close to orgasm, you can see the scrotum contract and the testicles raise. On the contrary, pulling the scrotum and testicles downward can reduce arousal and delay ejaculation, thus playing a role in treating premature ejaculation. 3. Penis squeeze method, the specific operation method is to put the thumb on the tether of the penis, index and middle fingers on the other side of the penis, just above and below the crown edge, squeeze for four seconds, and then suddenly relax. The squeezing pressure should depend on the degree of erection of the penis. Squeeze hard when erect, and moderately hard when flaccid and soft, so that the patient only has a feeling of pressure without discomfort. There are other methods of glans desensitization training, it is recommended to go to the hospital under the guidance of the doctor.
