There are books, at least in English, that are intended for teens (and they would be fine for an 11-year-old) that provide a decent, relatively unbiased view of sexuality. You could help her to get her hands on such a book.

Even something like this might do. Search the Amazon USA site for the ISBN 1557044449. It for a book called "What's Happening to My Body? Book for Girls : A Growing Up Guide for Parents and Daughters"
