These types of diverse examples of “vaginal geometry” (Roughgarden’s name) suffice several purposes past breeding. “All our body organs are multifunctional,” she points out. “As to why shouldn’t the latest genitals become too?”
Inside people-dominated kinds such as bonobos, by way of example, same-intercourse matings is located at minimum because common because the between-gender matings.
