To the guys suggesting shaving as a solution. No thanks; that hair hurts like heck as it comes back, and wiping still doesn't cut it for me.
Look at it this way. Say you got poo on your face, or any other part of your body. Would you just wipe it off with a dry paper towel, or even a baby wipe? Hell no! You'd scrub with soap and water, then rinse thoroughly Amirite?
Then why shouldn't your keister, which is in close proximity to the family jewels receive the same dignified cleaning??
