And is it really necessary to open it all up for the camera!?
Yes. Just the fact there is this thread is proof enough that there needs to be places where people can see what is normal. The nature of female genitalia is that it is hidden, hence hard for us to see in day to day life what normal looks like.

Logically, why would anyone think that genitals need to all look the same? Our faces don't. Big noses, small noses, pointy, bulbous etc. So why is it so surprising that labia, clitorises etc would be different?
