A slight curvature along the shaft of the penis is common and found in almost 40% of men. It will not interfere with sexual intercourse and performance. However, if the curvature is acute and is associated with pain on erection, surgical correction may be warranted. In that case, you should see a urologist. Otherwise just leave it alone.

It can be corrected by 'Plication' a minor operation. Please consult a general surgeon.
