I see this is your first post, and my first as well. Funny, wore CK one for several years before I started to experiment. Now, I find it "meh".
In line with what you are asking for, perhaps.

Move up by checking out everything by Dior. No going back then. Good luck!
As others have said explore the Dior line - Eau Sauvage is a must try, I'll 3rd or 4th the Mugler Cologne. Some cheapie cheapies that are worth checking out though they have short longevity are 4711, Yacht Man Blue and a few from the Adidas line. Izod is pretty nice as are a few of the Lacosste - just go try a few. Michael Jordan is lovely and Michael Jordan Legend is wonderful it's more for cooler days/nights but I have worn it light in warmer weather too, women like the Jordans by the way. Azzaro Chrome is very affordable and women love it. Oh and the Michael Jordan Flight is very light but pleasant. Now you can skip happily to any department and/or discount store and have a great time with all of the suggestions you have gotten - I will say none have steered you wrong from what I have read so far.
