I've developed a bad habit of getting a dab of poop on my right thumb when wiping as of late. Used to be a once a month occurance, but now I'm shooting 50/50. On the bright side, I'm much more aware of my hand-washing now. Perhaps it's a blessing in disguise.
A little late to this conversation...
But you're not bending your wrist. it sounds like you're taking your hand, starting at your ankles and rubbing it straight up to your neck to wipe your ass.
Bend your wrist. So as your fingers (with the TP in hand) and your elbow are touching your body and then push your wrist out as if you are trying to touch the wall with just your wrist. This will alleviate you sticking your fingers in your ass and getting shit on them. Either that or you're not using toilet paper.
1 - Everyone reading this is now trying it...either physically or mentally. Haha!
2 - I can't beleive I just told you how to wipe your ass. And I don't even have kids ready for that yet.
