My husband had been complaining that his butthole and taint sting and burn extremely bad. He really really looks like he's in a lot of pain. I finally got him to let me have a look and he had a raw spot / red tear in his taint area and one on his anus. What could cause this? Is he wiping too hard? Is the hair irritating and rubbing? Something else? He doesn't have any hemriods but these little cuts that are raw and burn.
