The general rule of thumb is to assume you can’t smell yourself but others can, and if you CAN smell yourself a little bit, others can smell you a LOT.
That said, I wouldn’t use this as a rule, people have very different sensitivities and you may never get a whiff of yourself even if you’re fermenting. Your nose is particularly good at tuning out regular smells like your own room, clothes, bedding, and most of all your own BO. It’s better to take preventative actions than trust that you will be able to tell when something is bad.
