Hey im a 21 year old Male. I have very itchy skin on the waist band, hips, groin area, penis, buttox, and legs. Im a Welder and am constanly working in hot sweaty weather. It seems to itch more at night. Usually the bottox area, penis, and hip area. There is no severe rash or anything. It becomes red after i scratch it obviously. I have noticed after scratching my bottox a few white raised bumps after scratching.
