What kind of Condoms?

Okay so i've only ever used Trojan ultra thin with lubricant and spermicide. I would like to try something that isn't so slick. With all the stuff on the condom, it just takes away from the friction. So what kind of condom should we use? If we bought unlubricated would we still have to use some kind of lubricant inside the condom? Or can you use unlubricated condoms with nothing else?
