no, not par for the course... maybe his kind of poly is this kind... it seems that he likes you and want to be with you, but also wants to lick pussy as a fun pass time, because, well, he likes licking pussy.
I'm sorry you believe you were deceived. If doesn't seem he was very up front with you about his kinks, but did say something about his lifestyle being important to him... the fact is that you now have to decide if you are okay with his lifestyle. You don't have to be and shouldn't force yourself to be, but getting to the bottom of what you are feeling and giving it some time to sink in I think may be a good idea. Then a good talk that is completely honest and up front before carrying on might help after you figure out where you stand.
