Husband suddenly doesn’t want oral

So me and my husband have been working through some things. He’s suddenly decided the husband and father role might not be for him but due to his job, this is a super normal thing for him to go through. Your average person? Maybe, maybe not, idk but him yes so I’m being patient. We finally were physical again after 10months, a quickie, and I felt weird going down on him because I wasn’t sure if he was ready. He’s very into that emotional connection and feels that we’ve lost that. I asked him about it and told him I wanted to and asked him how he felt about that and he said a quickie was good. So my husband would prefer to not have me give him head. We’ve been together 7yrs, married 4, have a daughter together, we’re getting past an emotional affair he just had, so it’s not like we’ve been together a few months and this is something new I’ve just discovered. We’ve been through a lot, we did it a lot, he always enjoyed it, and this is new. Any ideas on why and how to fix it?
