Go see your doctor. If it's Peyronie's Disease, you don't want to make it worse by trying to "bend" anything. Peyronies is the formation of a small amount of scar tissue in the outer sheath of the penis, which causes some bending when erect. Think as though you put a piece of take on a ballon then blow it up. In the area where the bend is forming see if you can feel a nodule or lump when you're not erect. That's a sure sign of PD, but it's not always able to be felt. If it is PD and you go stretching on it, you may make it worse, that's why you need to go see a doc, and take some pics of your erect penis to show him what you're talking about. PD is manageable, so don't freak out, just get on top of it. Vitamin E and anti-inflammatories are good too.
