I definitely have BO, but I can’t smell my own, typically. however, I also just don’t find the smell of sweat/BO particularly offensive.
I’ve started using not an antiperspirant, but a substance that acts like a deodorant, because my partner is VERY sensitive to smells and mine apparently sets her off pretty badly.
I don’t strictly forget about them, but I never think to buy them myself. Brussels sprouts.
