Yeah, I am. It's what doesn't disgust me.
Yeah, it is ridiculous if you ignore the fact that a human is the same species therefor it's been built into us to not consider kissing disgusting because it has a role in reproduction. On top of that, dogs only really started to be washed often enough (although it would have to be washed once a day for me to be neutral instead of disgusted by it licking my hand) in the last few decades, so that's been built into us as well.
