I am 46 years old and I was masterbating one night and once I was done I had felt a sharp pain in that area. It took a few days for it to go away but now when I get an erection It gets very painful. With inspecting my penis why I have either an erection or a slight erection I can feel on the top towards the back and it goes up towards the head, it feels like a tight string in there. It is stronger towards the rear. Can you help me with this? Will it eventually go away or do I have to consult someone?
