Husband won’t go down on me

So this is obviously TMI but I guess I’m just looking for advice or maybe I’m just hoping I’m not the only one 😭

The last time my husband performed oral on me was six years ago. I’ve since stopped doing it for him except on rare occasions when I kinda just feel like doing it.

The really awkward part is that I’ve straight up asked him to on two occasions in the past few months and he has rejected me. The first time he just acted like he didn’t hear me and the second time he just made an excuse about not feeling good. It makes me really uncomfortable asking because he is clearly not into it. And he definitely satisfies me in other ways, I really have no complaints other than this. I just don’t know if I should just give up or if I should try a different approach?
