I have to say from getting married to a woman who has never watched porn it has definitely made her more adventurous in the bedroom and given us both new and creative ideas. We watch it together sometimes and it usually leads to other things
But you want to look at the girly kind of stuff first; some of the stuff out there is just weird and not a turn on for everyone. Another thing that can lead to conversations and trying new things the "The Sunday Night Sex Show" on Oxygen, and as an added bonus after this you can watch "Bliss" which is softcore show that can help to wet her appetite for other things. Or at least it worked for me.
