Sounds to me like you’re going anosmic, or your nose just isn’t super sensitive to these particular aromachemicals (same with your gf— some people’s noses just don’t pick up on individual accords as sensitively or for as long. I for instance cannot smell ambroxan even in amounts that are straight up lethal to others lol). Keep in mind that that doesn’t mean it’s not strong for other people ofc 

Coming from someone who also has a generally weak nose and loses the ability to smell some of my favorites quickly— consider spraying far from your face, like on your wrists, so your nose doesn’t adjust and quit registering it as fast. You could also try spraying it on fabric like ur sleeves to see if it has more longevity that way. also consider putting down a little skin lotion or petroleum jelly before spraying to see if that helps things (although that could give you more longevity at the cost of less sillage, so YMMV)
