I first experienced masturbation when I was around 14 (I'm 17 now) and since then I never thought it was abnormal because I never cared. Even that I stopped, my male organ is always over heating, with dark red color (just like while sexual intercourse). I try to keep it as cool as possible several times a day, knowing that my whole body is often overheating as well, but it is still the same. However the problem scares me most about my genitals, and I don't know what to do. I refused to go to a doctor because I was shy of it.
Please tell me if you know a diagnosis of this case.
