Little things my SO does irks me to my core

So my boyfriend and I have been together for about 2 years and things are great. We get along super well, have a great sex life, rarely fight and have a lot of fun together. Still though there’s things that annoy me that I usually only find annoying for people I don’t really like.

The way he eats bothers me so much. How he sucks on his fingers when hes done. The slurping noise from a straw. How he Kisses my cheek and neck and leaves slobber all over. It’s not just a “that’s annoying” thing that goes on in my head but it’s more like “I despise you” and I want to get away

Does anyone else experience this? I’m just worried that it’s pointing to a bigger underlying issue. Hopefully I’m just overthinking as usual
