Drooling over a guy

i have always being a very rational person. Whatever i do, i must see if it's logical, whether it is full proof and 100% workable to my advantage and whatnot. But when it comes to love, my whole mind become messed up. i can't concentrate on my work and i can't focus on the things i need to do. All i think about is him and how nice his biceps and chest looks. He never took off his shirt before but i can see the linings of a six-pack. I can't believe i'm even thinking about this! I'm supposed to be studying!!!
