If you have a habit of excessive masturbation, it is recommended to quit it as soon as possible. In cases of phimosis, circumcision can be considered. It is also advisable to have a check-up at the hospital for your urinary system. If you are overly stressed, it is suggested to relax appropriately. I hope my answer helps you. As everyone knows, premature ejaculation can cause significant harm to patients, so it is important to seek treatment as soon as possible. In daily life, pay attention to dietary issues, and maintain a light diet, avoiding stimulating foods. Additionally, regular follow-up visits can be scheduled when necessary.
