I was chatting to a prostitute a while ago, and she looked at the time and said: "Oho, time to get to work" - and then, with an air of sarcastic praise to her upcoming customers - "Ohhh, you're so great, that's so big, oooh, never had sex like that..."

I was astonished. "What?" I said, "Is it not just plain sex?"

"Oh no!" She gave a laugh. "It's all about making them feel big and powerful. That's what they give you the money for."
