50 Shades of ?

In the little book 'Quotations with an Attitude' by Roy L. Stewart, Gloria Leonard tells us "The difference between pornography and erotica is lighting."

And Anonymous reminds us "Eros spelled backwards gives you an idea of how it affects beginners."

And George Burns said, "I can remember when the air was clean and sex was dirty."

The Earl of Chesterfield sums it all up for us saying "Sex: The pleasure is momentary, the position ridiculous, and the expense damnable."
