My penis curves to the left significantly, maybe 45-50 degrees. i would like this corrected and i am pretty sure it is not pyronie's disease. what mi?

Depends: It depends upon the curve. There is a medical condition which can cause a curve in the penis, and there is a treatment -- however, first you need to see your doctor or a urologist and find out if that's your diagnosis.

Peyronie's disease : Significant deformity ( of this degree) of the erect penis is most often due to peyronie's disease. Sometimes the deformity is severe enough to make sex painful for you or your partner. I would recommend you see a urologist for exam and treatment options.
