recently i found my penis popped and it didnt really hurt but now i see that my erections are like half an inch shorter because my dick wont get fully erect. any advice? even when i get a full ereciton its for like 2 or 3 seconds and succeeds down to half an erection in like 20 seconds or 15. and when its erect i still can pull it out like half an inch or more. any advice guys?
