Is it normal i can't cum unless i'm smelling my/my partner's dried spit

The smell of my dried spit or my partner's stinky dried spit turns me on so much. I'm addicted to it. Whenever I masturbate, I have to either smell my own upper lip or spit in my hands and use it to masturbate. It's a little sour but mostly sweet, and I think there are pheromones in it or something.

Anyone else like this?
