Ears and/or arm pits. No scratch that. MOUTH! Mouth all the way. Yuck! I peroxide my mouth. I was just telling my partner earlier during a toothbrush conversation how disgusting mouths are and how people should never use another's toothbrush. Lol. It really grosses me out. All that bacteria. Food between teeth. EW!!! I brush my tongue twice a day, sometimes more. I brush my teeth with soap, not toothpaste and use aloe straight from the plant for its anti-bacterial properties. I'm a freak about mouth germs.
