Why Does My Belly Button Smell?

Query: Why does my belly button smell?

Answer: "It's because your belly button is warm and moist because it never gets fresh air ( if you have an inner, which I do ) and that is the ideal home for bacteria, so what you smell is the odor of the waste that the bacteria gives off after eating the sweat... It's very similar to your armpits or when you sweat and don't take a shower."
