Of Human Bondage by William Somerset Maugham

Philip could not get Miss Wilkinson's story out of his head. It was clear enough what she meant even though she cut it short, and he was a little shocked. That sort of thing was all very well for married women, he had read enough French novels to know that in France it was indeed the rule, but Miss Wilkinson was English and unmarried; her father was a clergyman. Then it struck him that the art-student probably was neither the first nor the last of her lovers, and he gasped: he had never looked upon Miss Wilkinson like that; it seemed incredible that anyone should make love to her. In his ingenuousness he doubted her story as little as he doubted what he read in books, and he was angry that such wonderful things never happened to him. It was humiliating that if Miss Wilkinson insisted upon his telling her of his adventures in Heidelberg he would have nothing to tell.

It was true that he had some power of invention, but he was not sure whether he could persuade her that he was steeped in vice; women were full of intuition, he had read that, and she might easily discover that he was fibbing. He blushed scarlet as he thought of her laughing up her sleeve.
