No matter what kind of deodorant I use or how often I use it, my armpits always have a slight 'funk' to them. I shower every day, sometimes twice a day! They don't smell BAD, and I highly doubt it's noticeable by anyone else. But when I reach for things and get a whiff of my underarms it's really embarrassing and extremely annoying. Is this normal? What can I do to fix it?
