My very first boyfriend wore a cologne from Abercrombie and Fitch and Old Spice deodorant. To this day, when I smell either one I think of him. My husband wears Acqua Di Gio Cologne for Men by Giorgio Armani and before we got married he used the same laundry detergent for years. When we were dating I used to get upset when his mother would do the laundry because he smelled different. All humans associate scent strongly with feelings and memories. Do you want your significant other to remember you as smelling of sweat or cologne, because trust me he/she will always remember what you smell like.
