My hubby is like that. When I receive new FOs in the mail and ask him to smell any of them, he'll only smell them from afar. Basically, I'll take the cap off and give it to him, and he'll hold it at arm's length away from his face and wave his hand over it so that just a little of the scent wafts towards his face. That's as much as he can take when it's concentrated like that. Once it's diluted in soap and curing on my rack, he's fine with smelling them.
Lol, I once got a sampler pack with twenty FO's. I have them delivered to my work, and a couple of the ladies know to show up to my desk for sniffies when I get a box. After all three of us had gone through all twenty... Oh my, we had a major headaches, but it was worth it.
