QUESTION: what is the difference between peyronies and normal curvature? What causes the curvature in each case? or is peyronies just a label for penis's with a high level of curvature?

can it be caused by unusual masturbation techniques?


There is no such thing as "normal curvature".  Peyronie's describes a specific type of plaque or fibrous tissue band that typically causes deformity or curvature.  However, any scarring of the wall of the erection bodies in the penis can theoretically cause some curvature.

While this may be caused by rough, repeated masturbation, this would be quite unlikely.  It is thought that mild trauma or low grade injuries to the penis are responsible.

The bottom line is that if you have a curvature, have it checked by your physician or a urologist.

QUESTION: i have read that it is normal to have slight curves in your penis. Doy ou disagree with this? obviously all penises will look different. some will be short, some longer, some wider, so why should it be that they are all perfectly straight?

could it not point left or right? or be slightly bent and still be considered normal?


I do not agree that it is "normal" to have slight curves in the erect penis.  Any such curves would need to be quite minimal to be considered normal.

Curvature in the erect penis is always considered abnormal, but may not require any treatment.  The curvature can be mild, moderate or severe and can occur in any direction which depends on where the scar tissue buildup is located.

We would not consider a penis to be "normal" if it had a curve in it although it probably would not require any treatment either unless the curvature was severe
