which way do you whipe your ass?

This caused a heated discussion today and I was wondering which way does everone whipe, front to back or back to front?

I wet a tissue and squeeze the water out above my asshole to wash off the excess, I then use the turgid wet tissue to wipe any excess left wiping from the bottom up to my asshole. I then get a dry tissue and wipe from the top down to my asshole then turn it round a little to a clean side and wipe from the bottom up to my asshole. Between my asscheeks.

I then get a tissue semi-wet and squeeze the water out to make it turgid and clean off the poop which I have wiped into my skin (yes, it does get wiped into your skin no matter how you wipe, it's why I do this). I then dry wipe to get rid of the moisture and to wipe my asshole one last time, the inside of your asshole has evolved since the first multi-cellular life to deal with waste, so there is no need to stick the tissue into your asshole till there is no shit left on the paper.
