Like Butters from South Park. I sit backwards on the toilet and typically enjoy a cup of chai tea or continue watching what ever podcast I'm in the middle of or both.
I wipe toward my sack which may be seen as taboo but it can easily be managed. I pride myself on using very little toilet paper and fold it after each wipe. I don't get shit all over my hands! However...
Lets suppose you only have one piece left. You fold it twice and rip a small amount off the corner where the folds have been creased to create a hole in the center. Hold on to that piece you ripped out you'll need it later... Insert your index finger into the hole and do what must be done. Once complete you take that paper and wipe what's left on your finger but wait! Your not done remember that original piece? Take it to clean under your finger nail.
This might just save you one day.
