My Labs all lick when they are hungry. Shadow will come and lick my hand after he's eaten, too. I occasionally make the "mistake" of sitting down on the floor when it's coming close to mealtime so I can have cuddles with the dogs, but it always ends up with me flat on my back being pinned down and licked to death by three starving Labradors.
Ginny isn't much of a licker of people, but she does give tiny little tongue flick "kisses" sometimes. She does, however, lick soft furnishings and it drives me crazy. I have to interrupt her because I can't bear the noise. I'm very grateful that none of them are over-enthusiastic about cleaning themselves in that slurpy way. Ugh, it makes me shiver just thinking about it. Every now and again (a couple of times a month?), Squidge will have a sudden urge to chew her bloomers and that is pretty noisy, but it only lasts a few seconds so I can cope with it.
I was once at my friends' house with their male Lab and I was trying to work - he spent the whole day, it seemed, slurping on his bits. My nerves were in tatters by the end of the day. It's just as bad as a noisy eater, I can't abide it!
