Pornography is the explicit portrayal of the human body with the aim of sexual arousal.
"Do you know why there are no windows on adult bookstores? Or do you know why there are no windows on certain kinds of night clubs in the city? And I suppose your answer would be, 'they don't want people looking in and getting a free
sight.' That's not the only reason. You know why? Because they don't want people looking out at the sky. You know why? The sky is the enemy of lust. Now I just ask you... think back on your struggles. The sky is a great power against
lust. Pure, lovely, wholesome, beautiful, powerful, large-hearted things cannot abide in the soul with a sexual fantasy at the same time." - John Piper
