Paula goes to say a full negative, but gets it wrong.

Without asking, Paula took the coin out of Jed's hands, the slutty part of her mind feeling irate this was going to change, and wanting it to just be done already, sooner rather than later. She'd already decided to take the simple route, to change history so she hadn't been and was never a slut. But as she held the silver coin, and was about to say the words, that slutty part of her mind influenced her just slightly, so instead she said, "I'm a slut and I've always been a slut." The second the words left her mouth, Paula's eyes widened and she wanted to take them back, but the coin began to glow and blind both Jed and Paula.

When they were able to open their eyes again, their apartment looked different, with a more sensual design sense and even some porn film's just laying around, or sitting on their DVD shelf. Both of them got a new set of memories, one where Paula had loved sex since she was old enough to have it, and while she'd been dating Jed for a while now, they still did some swinging and other things that helped let off some of her impossibly strong sexual steam.
