My Penis Points Downward With A Little Downwards Direction Curve.

My penis points downward with a little downwards direction curve. I would like it to be straight or upward. Is it possible? Also my glans is black, i want it pink. My glans is having many marks on it too because years ago, just as a fun i used to rub it with hard things, usually it made them to bleed for a while too. is it possible to make glans healthy and restore?
