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 advises Ophelia not to give herself to a man outside of mariage because a "deflowered" woman is seen as damaged goods that no man wishes to marry.
