OMG a dolphins vag is the most complex vag on earth...fracking holy grail of vag's. This makes Seaworld look like a fracking brothel and Animal Planet look like the Spice Chanel. Next time I see one of those bitches out in the ocean I'm stuffing it.In fact, as a test of intelligence and dexterity, the interiors of female dolphins' vaginas became increasingly complex. The spermicidal nature of enzymes on the surface of the vaginal canal made it necessary for a male dolphin to navigate his penis through the entire length of the increasingly complex vaginal mazes, allowing himself to ejaculate only in the chamber adjacent to the cervix, the muscular ring that seperates the uterus from the vagina. Thus, only males capable of passing the test of the vaginal maze can impregnate female dolphins and produce progeny.
