At present, there is no clear clinical method that can show that glans sensitivity can be reduced by exercise. First of all, the cause of glans sensitivity should be clarified to distinguish between a normal state or a pathological state. The glans will have a certain degree of sensitivity under normal circumstances, and there will be physiological changes, such as erection, swelling and hardness, when sexual arousal occurs. If the glans is too sensitive, and even the symptoms of premature ejaculation should be standardized treatment, such as drug therapy, psychotherapy, behavioral therapy and so on. 1. Drug treatment: you can take pentazocine reuptake inhibitors, such as fluoxetine, paroxetine, sertraline, etc., can also be used externally with local anesthetics, such as bupivacaine, benzocaine and so on. All the above drugs need to pay attention to the side effects and adverse reactions of drugs, please use the above drugs under the guidance of a doctor. 2. Psychotherapy: increase self-confidence, eliminate anxiety about sexual intercourse, and solve the psychological and interpersonal problems related to premature ejaculation of the patient and his/her sexual partner through psychotherapy. 3. Behavioral therapy: Commonly used behavioral therapies include the squeeze method and the stop-action method. It is helpful for patients to receive moderate intensity of arousal for gradual training and treatment. If you want to reduce the sensitivity of the glans, please consult with a regular hospital in time, and do not try informal exercise, or it may cause damage to the reproductive organs.
