The blood vessel with the lower glans of genitalia was damaged, and the blood flow was particularly much. Then the blood stopped. Now it doesn't hurt if you don't touch it. It hurts especially when you touch it
Because I didn't see the picture you uploaded, just from your current description, it may be considered that it is the laceration of the foreskin ribbon. If there is a lot of bleeding and it has been unable to stop bleeding, then I need to go to the hospital for suture in time. If there is no obvious bleeding at present, pay attention to hygiene, disinfect the wound on time, apply regular anti-inflammatory drugs, and wait for recovery
If this happens, it should be the glans inflammation caused by inflammatory stimulation. You'd better go to the hospital to make a diagnostic index, take a look at your physical condition, eat less stimulating food, and see the symptoms through more than 100 countries for a period of time.
