My personal favorite (for me) is Victoria's Secret Very Sexy...it is THE perfect scent for me (the kind in the red bottle; not the pink one)
I absolutely love it when a guy wears Abercrombie & Fitch "Fierce". It smells amazing

My last boyfriend wore Mary Kay's Velocity for Men. Sounds weird that a guy would wear something by Mary Kay, but as anyone smelled that? It smelled wonderful on him!
