It makes me crawl in my skin whenever I see someone lick their fingers to turn a page (etc)

Saliva has always creeped me out. My man recently after 3.5 years found out my Kryptonite when I put my finger to his lip and he licked it. Without thinking, I crumbled into myself and went into the fetal position (I was on the couch). I learned this when I was about 6 years old and my younger cousin who was still a baby was drooling down his mouth, I threw up all over the backseat of my moms car 🤢
