I was studying in China. Recently, I came to Mongolia for work purpose. After a while, my penis started to itch. It's the tube inside. NOT the skin outside. It's not serious. And when I pee, I feel just a tiny bity hotness. Not bad. Just wondering why. Maybe somebody can help me.

I have a new girlfriend recently. This is not STD, right? I don't fool around with girls I don't know by the way.
