No. Let her have some privacy.

It's not the specifics about what's in the books, it's about the fact that she's stimulating her mind. You need to communicate with her (between the ears) sexually, the rest should fall into place unless you're terribly incompatible. You're fortunate that you know what's lacking, as she didn't communicate it with you for some reason. Now you can work on it.
