Do you wipe left to right or right to left?

My ass isn't sideways, so no.

I do both, first left to right, then right to left.
Then after a month of doing that I became a professional martial artist.

I have a rag on a drill, so circular

I'm more of a north east to south west kinda guy.

I have a bidet.

I don't, I just peel off the layers at a later date.

Inside to outside
