you need to see a urologist. this dent may be a plaque and you may be getting a condition called peyronie's disease. please get properly examined.
over the past year a "dent" has appeared on the left side of my penis most notable during erection. . i'm in my late 50's . . it does not hurt but my penis is no longer straight. is this something to be concerned about? what could it be? should i see a doctor?
