Is It Normal To Have Curvature In Penis?

I have notices a curve in my penis, it does not hurt and is not painful but i am not sure if this is normal, it is curved to the left kind of like a banana, and the only other thing is that when erect it used to go up to say 11 oclock abd now stand at like 8 or 9 oclock but it still is hard, is this something that comoes with my age, i am turning 39 this year. Thanks
