And keep you in the rear of your affection,
Out of the shot and danger of desire,
The chariest maid is prodigal enough
If she unmasks her beauty to the moon.
– William Shakespeare
Hamlet, Act 1, Scene 3. Some brotherly advice from Laertes as he warns his sister off Hamlet. He tells Ophelia not to give her virginity to a man outside of marriage because it can mean the ruination of her reputation.
