No, you shouldn't shave you may just worsen the situation. When the hairs start growing, they could become ingrown, get infected and hurt even more.

The itching could be fungus or scabbying. I would see a dermatologist if I were you. Before that, you may try some kind of antifungal meds but you need to ask correctly at the pharmacy, so you wouldn't get the wrong antifungal drug.

I have had a rash on the penis head and under the scrotum for the last 8 years. Used covospore which relieved for some months, but now has no effect. If i wipe the penis head just before bathing, it appears that a layer is forming around the head (normally opaque when not disturbed). Been to the doctors with various treatment, but it gets imbarrasing to drop your jocks for a nother man, or woman. Any suggestions other than a doctor. Is this normal?
