Penis discoloration

For about 2-3 years now, I've had a small discoloration on the head of my penis. The discoloration is not too far from the slit in the head of the penis. It's a greenish-brown color. The discoloration almost completely disappears when my penis is full erect.

I've only had one sexual partner since the discoloration began and they have not displayed any std symptoms either.

I have experienced no pain of any kind nor any burning or trouble urinating. Is this something more or less normal or is this possibly a yeast infection? Thanks for any help!

It sounds like it might be normal skin variations, but why not check it out with your doctor?
