Penile fracture can be treated surgically, with good results. But if your penis works and does not hurt, it might not be worth it. Google "penile fracture" and read about it on a medical website (not a chat room, there are a lot of guys writing in on chat rooms and getting varible advice), and then talk to a urologist.
