Husband not give head?

Does anyone else who enjoys oral sex have a husband who is uncomfortable giving it? How do you cope (with not getting it, low self-esteem etc)?

I love my husband, but he wont even give me a reason why he doesnt. He definitely cares about my pleasure and in no way am I trying to get him to do it. I just want to understand him better so that I can reason myself through my anxieties.

We’ve been having this conversation for three years. I can see that it kills him to upset me but he never gives me a coherent response.
