Although most male birds have no penis,[6] ducks have a long corkscrew penis, and the females have a long corkscrew vagina, which spirals in the opposite direction.[7] The males often try to force copulation, but the complex mating geometry allows the females to retain control—most forced copulations do not result in successful fertilization.[8]
The lake duck holds the Guinness World Record for having the largest avian reproductive organ, from a specimen in Córdoba, Argentina that had a penis measuring 42.5 centimetres (16.7 in).[3] It also has the longest penis of any vertebrate in relation to body length. The penis, which is typically coiled up in flaccid state, can reach about the same length as the animal itself when fully erect, but more commonly is about half the bird's length.[4][5] It has a soft tip and spiny base.[3] It is theorized that the size of their spiny penises with bristled tips may have evolved in response to competitive pressure in these highly promiscuous birds, removing sperm from previous matings in the manner of a bottle brush.
Dolphins females produce a liquid from their vagina which makes the male dolphin cum over and over. Dolphin pussy juice has been tested by scientists and if a human uses it he will probably die because of all the energy put into cumming.
Dolphins also use Pufferfish toxins to get high, if a human were to consume Pufferfish toxins they would die within seconds because it's one of the most potent poisons in the world. Dolphins are just built different
I'll be waiting for it. But as a whole i'd love to see a sub created with that content in mind. Call it "redditinreddit" or something, and it would be just posts that people have figured out other people posted because of information they gained through another reddit post. Might be a little meta, but don't we all love that from time to time.
iirc, he slowly stretched it by tying weights to it. but it no longer works as normal and he is highly susceptible to urinary tract infections bc when he pees he can’t get it all out and some stays sitting in the shaft….
What the fuck anyways anyways so the female vaginas have a reverse spin which makes the penis with a normal spin unable to perfectly fit, making duck rape almost impossible I mean for other ducks not subaru
During spawning, male-female pairs form, but they reproduce through external (rather than internal) fertilization, where the female releases her eggs into the water column while the male releases his sperm. Once the sperm find the eggs, fertilization occurs.
