My penis has been changing color to black gradually over the past 2 months. To clarify, it is the outside of the penis (not the glans). My skin has become a little wrinkly and loose around my penis and scrotum. Whenever i put my legs together, i feel inflammation in the pubic area (again on outside). I haven’t had sex yet, only oral from my girlfriend , who is also in her first relationship just like me. She has had no sexual contact with anyone else. Could anyone help me out here? I have tried lotriderm along with yeast infection pills that haven’t helped.
