Can you go nose blind to your own BO

I’m wondering because my coworker made a joke that I smelt bad. And I always feel that when people makes jokes it tends to come from some truth. So I asked another coworker if I did and she avoided the answer and went straight to how she wants to start bringing stuff for herself to freshen up @ work. Making me think she was confirming.

The part that’s confusing me is a legit don’t think I do. Like I checked everything on me down to my damn socks. I put deodorant on through the day. So am I just nose blind to myself??
