Hello,
15-20 degree bent is absolutely normal for a penis. Nothing has to be done. You will not have any problem during intercourse. Every penis is bit bent and a slight bend is normal.
But if however if your penis is bent to the left or right so much as to make it difficult or even painful to enter your partner during sex then pyrenoie disease has to be ruled out.
I hope it helps. Take care and regards.
Hi the majority of men some 85% have a curve on there penis so nothing to worry about lol Take care..............Bob
