Excessive licking of my face normal?

I have a 15 week old Small Munsterlander. We've had her since she was 9 weeks. She is a wonderful dog and the whole puppy experience has been great. Came pretty much potty trained, crate training took 5 nights, has been sleeping through the night for weeks, and clicker training is working really well.

I work from home so I am the primary care taker. She has definitely bonded closer to me than my partner, although she loves him too. She will often fall asleep on me on the couch in the evenings, and our morning routine is couch time while I drink my coffee, snuggles, and then she falls asleep on my lap.

What I am curious about is her excessive licking of my face. She will come inside from being out in the backyard, or getting settled in for the night, or just hanging out, and she will jump on me and lick my face for minutes. I will be sitting or lying on the couch, she will jump up, crawl up to my face, and put both paws on my shoulders. Then she will lick my face for at least five minutes. I try to put my hand in front of my face, but she gets mad and gets a little bitey (we are working on that, but she is a puppy). It feels like a grooming thing. My face is breaking out a little more than normal despite all the face washing. She often times falls asleep on me immediately after licking the you know what out of my face.

Is there anything I should know about this behavior? Will she keep doing this more and more if I let her? Can I enforce making her stop?
