Eyes shut during oral?

My husband loves blow jobs and I give him a BJ all the time so I know how it looks when he’s enjoying what I’m doing….however lately his sex drive has completely disappeared, he has no desire and I understand that this does happen on occasion but this has been a few weeks now where he has no desire….i gave him a BJ tonight and he had his eyes shut the entire time which is super unusual for him. He’s ALWAYS looking at me when I give head…my question is, does it seem like he’s bored of me? Was he thinking about something or someone else while I was trying to pleasure him? And btw I haven’t been able to get him off at all…his dick is like half soft all the time..:.idk what to think…I’m looking for some advice other than “talk to him” I want to know a woman’s opinion on this or similar stories…
