im 16 and ive never had smelly armpits but all of a sudden they stink, whats wrong with me??? D:

Hey, thanks for sharing. I understand that this can be a big problem, but know that many people undergo the same thing. You are definitely not sick. With puberty new skin sweat glands (apocrine and sebaceous) develop themselves, leading towards more lipids (amongst others) on the skin. This causes other, more lipophilic, bacteria to grow. The transformation of these compounds by these microbiota can result in malodor generation.
