I never said that TP is more sanitary. I was more concerned about poopy water dripping from your hands while getting the soap, or poopy water splashing onto your legs, etc. However as I've never used a bidet, perhaps these aren't problems. I think if you really want to get clean after a particularly messy poop, the best way is to have a shower from the crotch down.
