Try a bubble bath and shaving your hair down there will make u fresh. Iam a big girl to. I think you will be pleased. You can try baby oil after u shave if u like so no itch.
Sometimes bacteria can get trapped in the folds of the skin. Try using a small amount of antibacterial hand soap to wash the area and see if this helps. good luck
