My SO and bjs

My SO doesn't like bjs. When we first got together he did and now after being together 3 years he doesn't? Was kind of awkward after going down on him last night and he immediately told me to stop.. Is this strange? *edit* Now I'm wondering whether his always hated it but just went with it. And I haven't asked him I felt awkward last night and I'll feel awkward today. I haven't given him a bj in probably a year and he hasn't seemed phased by it (mainly my fear of a pube in the mouth 😂) but he hasn't asked for one or anything like that. Nope no teeth ladies. I think he just doesn't like it I'm alright with that haha. Update he just doesn't like it
