Is this normal??????

ok so last night i was watching cloudy with a chance of meat with my brothers on dvd and the part when flint and sam kissed gave me this funny feeling down there and i immediately thought about my crush. I have been trying to not think about him but its like really hard to not! when i went to bed, i layed down on my stomach and thought about him again and i think i was turned on? idk... im soo confused. then for some odd reason i kept on thinking he was in my room, or he walked thru my door or something and i thought about him comforting me. I was acting like he was actually there! then idk but i started crying really hard, and i felt like i was the most stupid, dumb, silly, foolish girl in the world! i cried myself to sleep last night, realizing that he would never be in my room, trying to comfort me. please help im desperate. i dont know what is really going on, and i want to know. can u get turned on by a thought? do u cry when u get turned on? why do u think i cried?
