No your dick won't shrink, but you can end up with permanent erectile dysfunction. If the blood is trapped in your dick for so long, it becomes deprived of oxygen. This lack of oxygen will cause damage to penile tissues. Any erection that goes on for more than four hours IS A MEDICAL EMERGENCY and you must go to the hospital where they will give you an injection to reverse the effect and bring it down.
why cant i just get some meds that i can just use if i get the problem again? i cannot see it as very comfortable going to the hospital for an erection. those guys barely pay attention to me when im real hurt, i cannot imagine the BS ill get for this crap. there must be something out there to do or take to fix this !!!
