As others have said, you are responsible for yourself, and that includes clearly stating to your partner what you want and need.
I've mentioned this over and over... I'm almost tired of it... but you can get him perhaps to face this with a little sex book swap.

You take the female book and he gets the male. You read She Comes First, a lot about approaches to oral on the woman but also about redefining foreplay and understanding a woman's body and physiological response... a very easy read and not "icky"... and he get the mans book, about what men like. You each read the book... mark sections you like and have concepts you relate to, and then you swap.
The nice thing about reading books and sharing them is you get to talk about the subject at hand through the book. Doesn't matter if its sex or relationships or money or faith or whatever...
The book becomes a vehicle for discussion. You aren't saying "you never do this"... you say "i was really interested in this particular page"...
It is no substitute for flat out open and honest talk. But it is a bridge to getting there. And you'll likely find some angles and perspective you might not have thought about.
I mention this book series often not because it is the definitive sex bible. It surely isn't. There are some controversial, and even inadequately unsubstantiated, statements concerning anatomy. But I like how its written... I like that a couple can share it starting with the idea that he gets to read about what he might like and make a "wish list" (tho it really isn't that)... and then he gets to read about a perspective on a woman's body that he probably wouldn't have done otherwise.
I absolutely love oral on a woman. There are so many great aspects to it. But it wasn't always that way and it took education, patience, and demanding lovers who were not afraid to ask for what they needed.
Thank God for women who are willing to trade the safety of silence for the power of communication.
