The foreskin frenulum is located in the lower part of the abdomen of the glans penis in the foreskin and connected with the lower part of the urethral orifice of the glans penis through the coronal groove. Its flexibility is strong, the penis can be obviously extended when it is erect, and can be obviously shortened when it is soft and contracted. Violent masturbation or rough sexual intercourse can lead to tearing or complete disconnection of the foreskin frenum. The foreskin system is rich in blood vessels and nerves, which plays a role in pulling up and strengthening pleasure in sexual life. The wound is small and can be recovered after debridement, but the wound is large and can be sutured if necessary! I wish you the best of health!
