The guy that I hung out with said I smell tart, What can I do to smell fresh 24-7?Since I sweat when nervous?

He said I dont smell but I have a unique smell. I tthink he was trying to say was that I stink.I dont believe that I think he is just being nice. I sweat when Im nervous.he said when your nervous you smell tart,then he said it smells like mustard. But he said couldnt describe. then he asked me what do i eat.
