I correlate it with the weird feelings that religion introduced about sex and let Al Pacino speak my feelings in Devil’s Advocate:

“let me give you a little inside information about God. God likes to watch. He’s a prankster. Think about it. He gives man instincts. He gives you this extraordinary gift, and then what does He do? I swear, for His own amusement, His own private cosmic gag reel, He sets the rules in opposition. It’s the goof of all time. Look, but don’t touch. Touch, but don’t taste. Taste, don’t swallow.”
