Butt Wiping Etiquette?

My nephew wipes his butt back to front, and my brother doesn't think there is anything wrong with that, I've always been under the impression that it's unhealthy. Who's right and why?Butt Wiping Etiquette?
For guys it does not matter, only that you do a good job. However for females it is imperative that they wipe from the taint back all the way. If they wipe back to front they get poopies in their wazu and that will cause an infection of the wazu.
I think that mainly goes for females not real sure though.
For boys i don't think there's a big difference but on the other hand girls need to go from front to back to keep that crap out of their other parts.
You are correct. You should wipe front to back. You do not want to get feces in the penis or vagina. You'll get an infection.
WTF? Who cares...
