Tilted Penis

My penis is very slightly curved, which I know is normal. However, what I'm not sure is normal is the fact that it's tilted in place when erect; the left side of my penis is "higher" than the right - if you'll forgive the fitting but otherwise silly comparison, not unlike the motion of a plane doing an aileron roll.

This issue is not remotely present while flaccid, which makes me wonder if it's caused by masturbation; however, my primary concern is whether or not this is in any way harmful.

Every time I've tried to look it up, I'm met with dozens of questions about a curved penis, and not a one about it being tilted like this.

It's slight enough of a tilt that I honestly did not notice until very recently - within the last month. I don't think the problem started that recently, though.
