am in love with my teacher

it is so wrong of me to fall for my teacher, but damn, to hell with principle and moral. his lips is so pink; i can't stop imaging kissing. gush, he is soo, soo cute, and his waist line is tempting, i could die this moment under his breath, in my arm.
I know I can't have him, but i have to try, even if it last for a moment, am OK.
So I always say to my self, but is not a enough. "when u have something; You start loving it, when you get used to it;you can't do without it, when you no longer have it, you start missing it."
the same thing with human beings,pets and objects. "but you can never miss what you don't have.i always say it's is better to have and miss than not have at all", my friend will always argue it "is better not to have at all than start missing it".
which one do you believe?.
Am In Love With My Teacher,
