Why would a nipple piercing smell?

Answer 1

Nipple piercings like any other piercing will smell due to the lymphatic discharge that builds up inside the piercing. This discharge ( a whitish substance ) needs to be rinsed from the piercing daily, this is a combination of body oils that, like any other natural oils will break down as it warms and generate an odour. Just like arm pits and the groin area, piercings need to be washed with soap and water daily to maintain good hygiene and piercing health.
