"Tiny, smooth bumps on the scrotum and shaft of the penis are normal and are simply hair follicles or sweat glands. These tend to stick out more when the scrotum is tight, as in cold weather, and are particularly noticeable on the erect penis where they cause a disproportionate amount of unnecessary concern."
