Hello, I ve notice that I got this discoloration where my scrotum and shaft of my penis meets. It some times gets irritated during or after sex. All i have to do is use a wet rag and it stops the itching right away. But the discoloration is still there. I am a married man and just started noticing this a few months ago. I am planning to go to the Doctor, just wanted a little explanaiton before I went.
