Maybe it's the type of perfume whe wears
I was thinking the same thing...a lot of men will find some kind of musks horrible smelling...I know there are some perfumes/oils I wear I find wonderful, Mr. Midnight finds them barf ville.

It could be a sachet she uses in her closet or any number of things..perhaps asking her what kind of perfume she wears might help.
However if it is too much then never take one for the team.
I have to agree with Mrs. Naughty, it is too hard for us to find a couple that we hit it off with so we end up with the MFM..so far that is all we have had luck with..
