This is such as interesting question and there are so many ifs and buts that go along with it - particularly the associations you form with a particular scent.
In my view there's nothing, NOTHING, so sexy as a confident man who is in control and exudes power (of himself), and his scent has very little to do with it. BUT, to be honest, even if Daniel Craig walked in wearing a patchouli frag I'd be sprinting in the other direction!!
Some scents are just too unpleasant to bear and the way many fools wear them makes me want to gag - perfumes are for smelling, not tasting!!
I love Vetiver on my husband. I don't necessarily think its a 'sexy' fragrance though, so don't know if I'd feel the same with it on another man.
He has the dregs of a bottle of Estee Lauder's Intuition lurking too and that's beautiful on him, quite close, and definitely one that makes me want to sneak up behind him and nuzzle his neck...
He wore various Calvin Kleins when I first met him and they left me cold really. Moved on to Issy and while it was okay it didn't really push my buttons. He did, I just didn't like the perfume. He likes Gucci for men now and as a fragrance I'm not overly impressed, but it makes him feel good and I just can't resist that confidence in him....
But, as has been said before, fresh sweat....gets me every time!
