I have a licker too! If anyone shows her attention it usually goes straight to licking. Sometimes even when no one shows her attention. When I visit my parents, she likes to do a drive-by lick on my dad. Just walk by, give one arm lick, and continue on. I'm also constantly warning new people that she goes straight for the face. If that means knocking you over in the process so be it (we're working on the jumping).
Unfortunately she also likes to lick things and not just people. This morning I woke up to her licking the other side of my pillow. And more than once I've rolled over and placed my head on a nice soggy side of the pillow. Ughhh.
I try to stop her licking things, but I don't worry too much about people. For one thing, there are too many more important behavioral things we're working on. Licking people doesn't really cause us any problems and I just see it as part of her personality. I think she'll always be a licker.
