Hi I'm starting to get worried that something's up with me. About 3 weeks ago my whole body started itching and I was getting bumps throughout my whole body then 2 weeks ago I got a red circle on the side of my penis it started itching just like the rest of the bumps on my body but it wasn't a bump. And now a week ago the head of my penis is getting very dry and is darker on the right side . What's wring with me???
