it could be many different things: allergic response to dryer sheets detergents perfumes in the toilet tissue poor wiping (stool is very acidic and can burn the skin) anal fissures yeast or bacterial infections etc. obviously without a thorough medical history and an examination it would not be possible to narrow down the many causes. if you want to get this problem solved see your medical provider.
why does my butt burn? . i walk around and my butt or around my anus on the outside burns. i think it might be because i wipe to rough after i use the bathroom but could it be something else?
