Circumcision is a very simple operation, but whether to circumcise or not depends on your situation. As long as the foreskin can be opened smoothly by hand after erection, all ghost heads will leak out. Then don't cut it. Pay attention to hygiene, and it is best to clean up the dirt before going to bed every day, so that there is no problem. However, if the foreskin cannot be opened smoothly by hand after erection, it is phimosis and the foreskin must be surgically removed.
