Sorry to here about your problem, have you had it checked out medically ?
I've read somewhere that [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]extender[/words] devices can help correct curves but I could be wrong, I've read some information by dr levine saying that pumping can help correct curvature as well, he even has a pumping programme where you change between 2 different size cylinders, I'll try and find the link for you.
I'm sure some of the long time vets will be able to advise you more than I can, good luck with your problem and I hope you can get it sorted.
