Sex is a chore

That’s what he said to me last night. We were talking about oral and I told him I love giving him blowjobs and the reaction I get from it is worth it. Then I asked him how he feels about oral and he said it is a lot of work going down on me, a workout and he only does it sometimes to please me. I asked him how he felt about sex and he said it’s a chore. He said sex in life is a chore. That completely destroyed my confinence. I’ve been picking up on that vibe when we do have sex, that it’s chore for him and if I didn’t have a higher sex drive he’d be cool with skipping sex and trade it for a nap. What am I doing wrong? What can I change so he doesn’t dread sex with me or think of it like a chore?
