does it get worse in a hott bath ? and maybe pain when trying to sleep ?

Hi there, I have similar dark spot at the tip of my penis. I think they appears do to the contact with chemicals that can affect the smooth skin. I am uncircumcised but my foreskin doesn’t fully cover my head and the tip is exposed all the time. My dark spots are more notorious in that area.
