As an update, the Dove bullshit seems to work although I cannot wash it off. I lather with soap and rise 3 or 4 times and it is still stays on. So I am starting to now apply it every 3rd or 4th day and use plain deoderant in the mean time.
The armpits are itchy all day whether I apply it or not. I don't give a shit about itchiness as long as I don't smell. Well maybe I give a 5% shit but almost zero shits.
It is still a horse fucking mystery why suddenly my body decided to start making body odor and being damp and itchy all of a sudden. Further evidence in support of transitioning to whalehood.
