Sorry, but *lol*, what a question! And what does it mean, she`s shy? i guess, she isn`t when she`s on her own. And maybe that`s the type of porn she prefers already when you are not with her, hehe.
ImO best approach would be to ask her straight to select a porn scene that she likes and let yourself be surprised. It is not on you to let her do anything anyway. Or am i wrong?
