Once upon a time I decided to make a tutorial about drawing vulvas... that is, the external genital bits on women. So I don't really need to explain all the internal anatomy for this (I think?) and I've run into some problems.. to explain the locations and such of the pussy I will probably have to elaborate on the whole pelvis, something I suppose I can draw in a passable manner but am bot sure I can explain. Location. Simplification.

tl;dr help me with pussy tutorial please, what should I include? How do I explain?
