I have two cats that are very affectionate to me but only one of them licks me. The one that licks me, Kira, is higher on the heirachy that they've established and the one other one, Jadzia, only licks Kira. The closest thing I get from Jadzia is a single lick as though shes tasting me. And yet of the two of them I would say that Jadzia is the most affectionate though she likes to play bite while Kira doesn't normally. Why doesn't Jadzia lick me?
