I wore it today, as a matter of fact. Of the four or five Creeds I own, this is the longest lasting. Fourteen hours after I put it on, I can still smell it (faintly). I don't remember it even being a note that's supposed to be included, but at the moment, smelling my wrist, I smell a little bit of vanilla.
I am very fond of Royal Delight - it is sweet smelling, slightly leathery, and starts out with a citrus note, that fades out pretty quickly to a nice floral. I enjoy it a lot.
I would say it leans *very slightly* to the feminine side because the floral lasts a while and is pretty strong. But it is certainly wearable by a man. I'd be surprised if you didn't find it (you knew it was coming) delightful.
