Do you have an idea of what sort of scents you like: woods, smoke, tobacco, floral - things like that? Also, do you want it to project so that others might be apt to smell it, or do you like something close to the skin? Do you want something that you might find available at a large department store, or would you be willing to search it out, say by paying for samples?
I ask these questions because I could tell you what I like, and you might not be willing to search out my suggestion. If you are wanting department store fare such that you can go there and smell them on a card or wear them for testing, well, Armani Code would work, and so would things like JHL, Devin, Obsession, Escada, and those are just ones I like.
