Is it normal that my young teacher's hands distract me?

Hi im 17y/o girl and i started taking private lessons with a group of my classmates, and the teacher is a young guy in twenties and these days i noticed that he has beatiful hands they're large just perfect , im not really good in english so i can't discribe them well, any way and so every time i look at his hands i want to touch them, put them on my face, i feel my private place Start pounding/beating or whatever we can call it and it Get really hot i cant actually hold myself from thinking of tuching them or just suck or lick them even if i dont want to think ot this ( sorry to tell you this :/ ) so it distract me alot, im not sure if this is normal because i dont love this teacher or like him or anything
I really hope to here you opinion this never happend to me before
