From my own collection I'd venture:
Penhaligon's Douro Eau de Portugal
Guerlain Vetiver (despite it feeling masculine on myself, I've smelt it on several female friends and it was wonderful)
Narciso Rodrigez pour homme
And others that I'm aware of, Paco Rabane Black XS and JPG Fleur du male both spring to mind.
I'm sure Basenotes will never hear the end of the 'fragrance is genderless, wear what you like' debate, although I personally think that there are many 'female' fragrances which are simply too feminine for the vast majority of men to wear - that said, I occasionally wear Guerlain Mitsouko, and am about to purchase Caron Tabac Blond. And interestingly, three of my frags which I consider the most masculine (Tom Ford Tuscan Leather, Serge Lutens Gris Clair and Serge Noir) are all sold as unisex.
