About a year and a half ago I started to experience pain in the head of my penis while in an aroused state. As the pain increased my penis began to bend downward in a curved shape. I will describe it as follows: where my penis begins it was straight and from there it began to curve downward along the shaft until it reached the end of my penis. My penis had a semi-circle type shape to it. Also my penis became shorter. I was frightened and afraid to have sex.

The pain eventually went away and the downward bend in my penis went away. However the size of my penis never returned to it's normal size. It is now shorter by 2 inches.

Can you help explain this and give me some advice.
