What is the reason for the broken skin on the penis

There are many reasons for broken skin on the penis: 1. It may be due to trauma. For example, external impact or accidentally touching some sharp objects may cause the penis to show broken skin. 2. It may be violent friction. If there is too rough masturbation or sexual life when the action is too rough, the female vagina is too dry and excessive friction may cause the penis to break skin. 3. Virus infection. If a man has genital herpes on his penis, it may also appear as a broken skin after the herpes ruptures. 4. Some sexually transmitted diseases, such as syphilis, may also cause ulcers, broken skin ulcers, etc. on the penis.
