Hi, Im 17 yrs. old. My partner and I are sexually active, But we haven't done anything bad. i've done a lot to her. but nothing with my penis. We mostly feel each other up. But i have realized i am getting itchy underneath my ball sack. There are little small bumps. They are red. When i go to "inspect" It feels hard down there, and bumpy. I dont know what to do. Please help!
