Why do I have leg asymmetry?

I noticed that my right leg is bent different than my left leg. This affects me because sometime when I walk, it's more difficult to pick up and move my right foot than my left, and it's something I have to consciously think about when moving, making me look very awkward and uncomfortable. In the photo, my right leg is on the left, aka "my right".

What is the cause of this? Is this even something to be concerned about, or is this within the range of "normal"? Will it worsen as I age? Is there a specialist I can go see for this issue if it is not normal?
