At Double X Science, Jenny Morber has an excellent piece about the wide range of diversity seen in human lady parts. "Are you normal? Yes. Are you average? No. Most likely," she writes. What follows is a fascinating tour of human biology, from the different lengths and colors of labia to the wide range of shapes exhibited by the inside of the vaginal canal, itself. Even better, all of this can change over the course of an individual woman's life, rendering "average" even more meaningless.
