For the past two weeks, my testicles have felt sore. Usually, they just hang there and I don't notice them, but I can feel them all the time now. Recently, when walking, the area between the testicles and the butt feels sore and itchy when I walk. Also recently, there's a ring at the base of the penis that's red and itchy. The skin on the testicles is now also red, but not itchy. I imagine I should see a doctor, but I'm in Italy and won't be home for another week.
