I love how people say this. Dude, other people will not tell you if you smell bad unless you ask fairly insistently. It’s awkward, and people would just rather ignore it than broach that awkwardness. Tell someone you work with and trust everything you have just written here, and see what they say. My bet is either you are “that smelly guy at the office” or “meh you smell kinda funky, but it’s not horrendous”. Either way: wash ya ayyssssss
