As many of you know, I'm a sex educator, and I'm always looking to keep my own list of resources updated so that what I recommend to others is the best stuff out there!
I've been pointing people to the Everyday Bodies Project as a great source of photos that reflect the diversity of real women's bodies. And the art photo book Petals (although it's b&w). Femalia is great, too, although it's out of print now and hard to track down.
Are there any other good sources -- either books or online -- of diverse vulva photos that anyone would recommend?
