I recently noticed that the bottom of my penis shaft is slightly discoloured. Even though this hasn't caused me any pain or discomfort I'd like to know if i should be worried or not. Thank you!

Good evening my young friend.
There is nothing to worry about. I have the same thing on the under side of my penis. My is even darker. I think it is normal Have not seen to many over the year.
But I think your good to go. Be careful and take it easy…Ken
Thanks for your reply Ken! I appreciate it!
Nor Problem
Just relax your good..Ken
