Why would you expect someone who doesn't think to tell you they've had unprotected sex to follow a rule telling them not to?
Edit: Perhaps you've misunderstood Dagferi to mean that she doesn't care if her partners have unprotected sex without telling her. I'd suggest her meaning is more along the lines that (short of following them 24 hours a day) she can't stop anyone from doing anything with anyone else, but she can stop them doing it with her. Therefore, if her partner chooses to have unprotected sex elsewhere they are also choosing to stop having it with her.
