What are the red dry spots on my penis?

In the beginning they were 2 small dots. But in the last few months all the spots are quite noticeable. They didn't appear suddenly, I would say increased over 4-5 months but in general the condition has been present for a year. They are not blisters- more like red dry skin which falls off and leaves the new red skin. No other symptoms like itching, pain etc. / just to mention, I have an itchy bump where the skin is also dry - not sure if related, I just may be afraid I have transferred it./ Thank you.
