Licking is not a sign of love or like, if you think such a feeling can be directed by rabbit towards a human being (which I doubt - I believe in trust a lot more than love / like in that case). It's a sign of submission. Most females won't lick you because females are generally dominant in warrens. Aki is a pretty dominant doe, but she will lick me when I pick her up. Because she wants to get down, so she pledge her fealty or something (I think she believes picking her up is a way for me to establish hierarchy) and, being the benign leader that I am, I put her down.
Tybalt never licked me, but he barely licks himself and only give a small lick to Aki after much proding (he is lick-lazy)
