I'm reading A Song of Ice and Fire, and there's a sexually explicit scene where Jon Snow and Ygritte have sex. Jon does something, and afterwards Ygritte says:
Afterward, she was almost shy, or as shy as Ygritte ever got. “That thing you did,” she said, when they lay together on their piled clothes. “With your . . . mouth.” She hesitated. “Is that . . . is it what lords do to their ladies, down in the south?”
“I don’t think so.” No one had ever told Jon just what lords did with their ladies. “I only . . . wanted to kiss you there, that’s all. You seemed to like it.”
“Aye. I . . . I liked it some. No one taught you such?”
“There’s been no one,” he confessed. “Only you.”
“A maid,” she teased. “You were a maid.”
I don't really get what this conversation is about. Why does Ygritte ask about ladies in the south?
