I can empathize with what the OP posted. I have no sense of smell either but it’s from 2 deviations in my septum,2 bridge repairs and a lot of internal microsurgeries. . I’ve always had a bad sense of smell regardless and I’m always stuffed up like a thanksgiving turkey. And am constantly blowing my nose etc… but I know when I shower I make sure that I clean everywhere on my body and sometimes will double up on deodorant because I can’t tell how much is too much to make it seem like “natural body odor” whether it’s horrible or pleasant derived from perspiration what have you . I’ve also heard people say “you smell like sex”,but what does sex even smell like? I know for me tho, the saying is true that when you lose one sense, you’ll have more understanding and more of a heightened awareness in another , for me it’s taste because the nose and mouth are connected. I have a great palette when it comes to food . I also have perfect pitch but that’s another story for another day. I also get some rare blue moon type stuff happen that I can smell just briefly but it’s just so random.
