The male banana slug’s penis is the same size as his body, so he needs to find a female the same size as himself. Otherwise, his penis is too big for her and she chews it off.
Female porcupines are only interested in sex for 8-12 hours out of the
ENTIRE YEAR! Males have to woo their woman by peeing all over her from 6 ft away. If she’s into it, then she makes him mate over and over again, until he is exhausted. If he’s done before she’s had enough, she leaves him for another male.
Everyone has sex with everyone else, for any reason at all. ”Hey, you brought home fruit? Let’s do it!”
Ah, the art of penis fencing. Since flatworms are hermaphrodites, they duel to see who will be the male and who will be the female. Whoever gets stabbed first by the penis gets to be the woman.
The males are definitely jerky in this species. You see, the female carries her eggs around in her mouth. The male has spots on his anal fin that look like eggs. So the female, thinking she dropped some, moves in to pick up her “lost eggs” and in the process gets a faceful of sperm, compliments of the male.
Only around a dozen male drones get to mate with the queen bee out of a thousand or so, but their genitals explode and their broken-off penis acts as a cork to keep their sperm inside the queen.
And here, you thought your boyfriend was a parasite! Once the male anglerfish reaches maturity, his digestive system shuts down. Since he can’t eat or digest food on his own, he finds a female, bites her and releases an enzyme that bonds them together permanently. Voila! No work required by the male, except for releasing sperm every now and then.
This little marsupial is so sex-crazed, that he will hump until he keels over and dies of exhaustion. He will spend up to 12 hours mating with one female. YIKES! Insatiable to the core, he goes from female to female, mating until his immune system becomes suppressed, he develops severe ulcers and gets infected by parasites and dies at the end of the mating season.
Talk about dominant women! The female hyenas are more aggressive than their male counterparts, and are even equipped with a pseudopenis (basically a realllly large clitoris). The males then have to artfully insert their penis into the pseudopenis in order to mate.
In a family group, the largest member is the female and the second-largest is the male. When the female dies, the male then switches sex and becomes the female of the family.
Snails are also hermaphrodites. Strange fact: their penis is located on their neck! As cracked.com put it, even though they have both parts, they still need a mate because snails, like Jesus, frown on self-love. Instead they stab each other with calcium “love darts” to convince their partner to trade sperm packets.
Panda porn. Got to see some of that at the 2007 SCB conference, while sitting with my dad. AWKWARD. It’s no secret that zookeepers have had issues breeding pandas in the past. Now pandas of a certain age are shown “panda porn” to get them in the mood.
The male hippo will put himself on display, defecate on himself and use his tail like a propeller to spread it around, in the hopes of attracting a mate.
Red-sided garter snakes
The female ends up in a giant snake orgy called a mating ball, which can consist of up to 100 males all trying to mate with the one female. It’s a big tourist attraction up in Manitoba, Canada.
Argentine lake duck
This duck has a 17 inch long, corkscrew-shaped penis, with a brush on its end. It uses the brush to remove any sperm left by a previous male. And if its female tries to escape, he uses his penis as a lasso to bring her back.
These guys aren’t guys at all. None of them are. They are ALL females. How do they reproduce, you ask? They engage in a little girl-on-girl humping to encourage the female to reproduce on her own and produce an exact clone of herself.
The phrase “traumatic insemination” says it all. Male bedbugs have such sharp penises, that they basically just stab through the female’s body to deposit their sperm.
Yet another hermaphrodite, sea hares will form a line or circle, one upon the next, to mate.
Also known as the paper nautilus, this is a species of octopus. The male produces a ball of spermatozoa in a special tentacle called a hectocotylus. When he sees a female he likes, the male then detaches his penis to swim by itself to the female!

This detachable swimming penis was actually first noted by an Italian naturalist back in the 1800s, who mistook it for a parasitic worm!
Its a matter of size
Here’s some info you wouldn’t expect. Barnacles have the longest penis to body ratio in the entire animal kingdom. The penis can be up to 50 times the size of its owner! Yet gorillas, which can weigh up to 450 lbs or so, have penises less than 2 inches long! Stranger yet: the world’s longest sperm actually belongs to fruit fly of the Drosophila bifurca species. Once uncoiled, a single sperm measures 2 inches long, which is 1,000 times the size of human sperm!
