My Balls Hang Very Low And I Am Very Un

My balls hang very low and I am very un computable when I go to lay down a night. My penis touches and rubbs me and is eritated all the time. I have changed different kinds of underwear and I take bathes all the time, with the rubbing together all the time is making me lose a lot of sleep. Please tell me what to do. I have prayed about this thing and I asking a doctor what you would do. I would be very grateful if you could help me.
