Have you ever watched the movie the mirror has two faces? It's a love themed romantic movie of the 90s staring Barbra Streisand. In it she plays this love professor who mistakenly arranges to marry another professor under agreeable circumstances; terms being no sex. The whole movie is about misinformation and misunderstanding and how he presumes that she doesn't want sex because sex is bad and sex kills relationship and relationship should be based on agreeable terms rather than lust.
She says, when sex is out of the equation the relationship becomes almost spiritual to a whole other level. That it's no longer a conquest of love and two lovers but this magnificent spiritual bond that transcends beyond.
