I'm 20 years old now and I have sex with my gf for 3 three times. For the third time I got my penis injured accidently, the problem is bleeding when I remove the forehead of my penis. It feels a litte bit hurt and to be more specific the injury is cause at the low part of my penis head. It seems a little bit swelling and bleed if I remove the skin. So the question is
how can I cure for that injury?
how long would it takes to be cured?
I need to know it quite quickly.
