I don't know if I agree, Net. Of course you know your W best but from a woman's perspective I see it differently.
I completely understand the sensitivity to smells thing. I had wicked bad morning, noon and night sickness when I was expecting D12 and still to this day some things will turn my stomach. Usually cooking smells, though.
But cologne is a personal item. I just think about it's purpose - to attract & be noticed. If I found the cologne of a man I had no romantic investment in offensive, say a coworker or my brother, I would simply explain my sensitivity to it and ask them to refrain from wearing it around me. I certainly wouldn't be making a point of going out and buying them a scent I found pleasing. Let me put it to you this way: Let's say a number of years ago, when you and your W were happily M, your W came home with a bottle of Dolce & Gabbana and said it was for the guy in the next cubicle in her office, wouldn't you have a bit of a WTH reaction?
I can only speak of my own experience and I can say with absolute certainty that if I had bought cologne for someone other than my H, he would be extremely suspicious of my motivations. And I'd think he'd have very good reason to be.
Just my $0.02.
