You should be able to move your foreskin back and forth over the head. It should glide smoothly back and forth like that. Most uncut guys masturbate that way - by pushing and pulling the foreskin back and forth over the head, with a grip on the shaft skin or foreskin. You don't need lube doing that, although if your foreskin and head are dry, some lube can help. The gliding motion of the foreskin over the head is said to be very pleasurable in uncut guys (I can't speak first hand about this, as I'm cut unfortunately).
Some uncut guys choose to masturbate by retracting their foreskin behind the head, holding it there, and stroking the head directly. You will likely need lube for this.
