I get musty very easily why is this?

Doctor can evaluate: Haven't seen good research linking certain foods to the smells of bodily parts or bodily secretions. Basic ideas can be followed, such as cleanliness (bathing removes bodily oils, which come from sebaceous glands, which have bacteria and can carry oils/flavors from spicy/odorful foods). However, overwashing damages skin cells, and can make aromas worse. Possibly hormone-related? Doctor can check!
