Pain may occur in the penis after masturbation. If masturbation is too frequent or too strong, it can cause pain in the penis and even edema in the glans and foreskin. These are local pains that occur because of bruised edema due to impaired local blood circulation caused by excessive stimulation. Stop the relevant stimulation and the pain can be gradually reduced after rest. If you masturbate with excessive force while the penis is erect, the white membrane of the penis can be damaged and cause rupture of the white membrane or bleeding of the white membrane of the penis, which can cause pain. Frequent masturbation causing damage to the corpus cavernosum can also cause hardening of the corpus cavernosum, which can lead to pain after erection or symptoms such as pain in the body of the penis. Masturbation process can cause penile pain if it causes local contamination or causes urethritis, etc. It can be accompanied by abnormal urination or purulent discharge from the urethra, etc. All these causes can lead to penile pain.
