Normal penile curvature versus Peyronie’s disease

The human penis varies from man to man in the size and shape. Peyronie’s disease means a curved penis, but not every curved penis means Peyronie’s disease. Thus, we should answer the following question:
⇒ When can we consider the curved penis normal, and don’t worry about it?
When the penile curvature is less than 30 degrees, no progressive curving, and no painful erection, it is a natural condition that doesn’t need medical intervention.
If the curve increases, there is a painful erection, or it is difficult to have sex, it may be Peyronie’s disease, and you should see a doctor.
In normal conditions, the curved penis may be useful for some sexual positions, and even some people prefer it. Some people say that it may stimulate G-spot better.
