This is a very embarrassing situation for me. I would be humiliated if anyone saw my private parts like this. Please keep this picture of my penis private.

Over the past year, some areas of the skin on my penis, testicles, and thighs have become much lighter in color. Is there any treatment that can be done to correct this? I believe this is called hyperpigmentation, but I am not sure. I would like make the skin color normal again. Thank you!
