When I sneeze I can smell it, why?

When I sneeze I can smell it. I've asked others if they could smell my sneeze or if it was just me, my mother laughed at me and told me it was just me, she didn't smell it. I later asked my husband and he says he can smell it. He thinks I'm weird since his don't smell. Always been able to smell it, any ideas why, or is there something wrong with me? What am I smelling?
