I don’t use deodorant because all the ones that work use aluminum for some reason, and all the ones that don’t use aluminum fucking suck and don’t stop me from smelling.
After living with someone who used deodorant for two years I can say that the deodorant smells way worse and stronger than what their natural body odor is. If you want you can always just wipe your pits with IPA or a wet wipe or something.
