[Mia and Wickett]

This might seem silly, but I want to make sure I don't make Wickett sick.
Since we got him, he absolutely loves to lick lips. Is this common? We've gotten used to it and find it funny. But sometimes I wear lip gloss, something like the flavored Victoria's Secret ones or other types. He'll still lick my lips when I'm wearing it (he actually really enjoyed the Victoria's Secret flavored one). Is that ok? It's not harmful to people, but is it harmful to dogs? This isn't an every day thing, more like once or twice a week? I try to avoid him kissing me when I'm wearing it, but who can resist those sweet yorkie eyes that are dying to give you affection?
