As salam alaikum wa rahmatullahi wa barakatuh. Ustadh, I sometimes feel a discomfort toward certain eating sounds, like licking fingers or a plate, and I may look away, or make an unconscious face when I feel uncomfortable without intending disrespect. I still believe it is Sunnah. Is this kufr?

Ustadh AbdulAziz al-Haqqan

Allahu Akbar! This is a huge jump, do not involve kufr in this. This is waswas that you really need to ignore or seek psychiatric help with.
