I don't want to suggest anything specific because I don't know what your husband likes, but here's what I did to make my husband go crazy:
Everytime I tried a new scent, I would ask him to sniff and tell me what he thinks. He never really liked any of them. One day I was wearing Spring Flower and I noticed he was almost like a dog in heat over my scent. He couldn't stop sniffing. Okay, so I made a note. He obviously liked the ambergris/animalic/musky drydown. Fast forward to a few days ago. I tried Pink Sugar Sparks for the first time. He sniffed it once, and then kept coming back for more. Hmmm. Interesting. I felt the drydown was very musky, so I think I have pinpointed that he really likes musk. So next I am going to try Prada candy, which has a really musky drydown, and see what he thinks.
I figured by doing a little experiment, I could really hone in on what drives him crazy. And I think I may have figured it out. Try this with your man and see if you can pinpoint his weak spot Good luck!
