Rabbit body language and vocal cues (sounds or noises are used to send 'messages' or 'to speak' to you, other rabbits or pets. They may be used to show anger, happiness, excitement, contentment, fear, disapproval and so on.
Therefore, to be able to respond accordingly, it is important that you learn how to interpret the various messages your furry critters may be sending you. One such message is licking.
What does it mean?
When this pet licks you, he or she is trying to show its affection or she trusts you. In verbal terms your furry critter is trying to tell you ‘ I love you’, ‘I care for you, or ‘ I trust you now’.. He or she is not trying to sniff you. Neither does it want to nip you, or does need any salt licks.
At times this behavior may be accompanied by gentle nuzzling (a rabbit rubbing its nose on you) as well as nibbling you a little bit. These are all signs of affection.
Also, you may also notice this pet licking and nibbling another rabbit especially if they have been bonded well. It is still a sign of affection and love. Bunnies groom those they love including you.
However, if your bunny does not lick you especially your hand, leg, and so on, it does not necessarily mean that he or she does not love you. Some have ‘laid back’ and shy personality and they may express their love in a different way.
Licking your clothes or any fabric around you may also indicate affection or it could indicate this pet is probably confused, not knowing where your clothes and furniture begin. Therefore, sometimes this behavior may be a sign of submission as well as confusion 
Sometimes, it may be a means of accepting dominance, i.e., by “licking the dominant's forehead and ear”  or welcoming and acknowledging the dominance as well as welcoming a bunny to their warren.
Dominant bunnies are the ones that are often licked therefore yours may also be telling you the same thing, you are dominant. However, dominant bunnies sometimes also do this to their vassals.
Finally, this may happen when this animal wants to be petted  or want to be given food. It is still a sign of love if she or he wants you to pet him/her.
If your rabbit licks, nudges or nibbles you, it is most likely he is affectionate to you. However, you need to carefully consider the circumstances under which it happens before drawing your conclusion.
