Oral?

So my husband was a virgin when we first met. Me? Not at all. So when we first got intimate with one another, I pretty much had to show him the ropes. Now its been 4 years together and 3 months married and he has yet to go down on me. And I cant tell if he just doesnt want to or if he's intimidated of doing it. Have any of you ladies ever been in a relationship as such? How did you handle it? Is oral important to you?
