I've always found the Karma Sutra books very enlightening regarding understanding my own female anatomy and sexuality. Taoist stuff is good, too, in my mind. Oh... crap came across another really good one... well... let me find it.
Anyway. Exploring my female sexuality was, is and continues to be one of the coolest, scariest things I've ever done.
Share ALL those books with your H, too.... but in a covert type of way... "Hey, H, I was reading about this thing I thought I might like to try..." show it to him... and then that way, he doesn't necessarily have to admit to something he doesn't know, nor will it feel to him like he hasn't been doing it right for you... you know?
