Accidentally made my bf uncomfortable

So. We were talking about sex and he asked me if i would ever do i rim job. I said that it wouldnt disgust me but it would turn me off. I sad it rll quickly bc i thought he would be disgusted if i said yes or whatever. And he just nodded and when i asked him if he would want me to. He got really defensive and said hell no. But im not convinced. He then stopped speaking to me. I dont know what to do. I saw some videos and i totally feel ok w doing it now but i dont know if i should tell him or not... But he has been acting weird for almost one week now lol.

Also

Does it feel good for them? Im genuinely curious bc i dont feel anything
