14 Days of Genitals, Day 9: Marsupial Snatch-Attack

Marsupials are strange critters with their mysterious pouches and non-placental birth, but they get even weirder when you take a peak inside:


 I spy with my little eye.... THREE VAGINAS!


That is correct everyone, female marsupials (kangaroos, Tasmanian devils, wombats, opossums, etc) have a triple-vag set-up. The lateral vaginae are for sucking up sperm, and the middle vajayjay is for pushing out the itty bitty joey. They even have two uteri for the appropriate vagina-in-use. 



But because they've got a double set, female marsupials often have young at different stages of life: one in the pouch, a bigger one bouncing around alongside it, and a developing embryo on the way.


LOAD 'ER UP!

How do male marsupials deal with all this confusing machinery? Evolve double-pronged penises, of course.


More of an opossum than you ever wanted to see
Their willies are wiley too - here's a NSFW video of a kangaroo penis trying to escape from his body, all narrated by an unexpectedly charmed Australian lady.


But just in case that exploratory dingleberry dick wasn't weird enough, we've got one final detail for you: their balls are in front of their dicks. 




Thanks to one of our readers for the tip!
