Well, last time things went rather nice, so let's skip plain naughty this time and go for nasty! We already learned that girls can be really nasty but of course, guys aren't much better. Well, at least they usually have to keep their partner alive to reproduce but you know guys - some just want to put their penis into every hole they find. And some are even willing to make new holes - welcome to the not so happy world of traumatic insemination!
Okay, you're still here? Well, you have been warned...
Let's start with silkworms. These are actually kind of cute critters, looking a bit like earthworms with lots of stubby legs and two antennas. And their mating begins innocuously enough as the male attaches his spermatophores, packages of sperm, to his mate's back. But then it gets ugly as the spermatophores dissolve her skin and let the sperm seek their way to her ovaries through her body. Females that have mated several times look like the victim of a shotgun attack afterwards...
But it gets worse! I mean why gluing your sperm to your girl's skin if you can just inject it? That's much more convenient, right? And all you need is a syringe-like penis! And that's what several animals actually do. Yes, stabbing sex... And in the roughest cases that means piercing the female exoskeleton as happens in certain spiders and in an especially cruel way in bed bugs. Here the male wrestles the female to punch his dagger-like penis into her armored belly. If you really want to see that, click here...
Now, in any sane person's mind the one word "Why?" is reverberating. Why do some animals take sado-masochism to a penis-stabbing extreme? Well, for the guys the answer may be simple: It is the perfect rape - the female cannot prevent him from mating by shielding her genitals and other males cannot create any mating barriers against their competitors (Yes, that's a thing and boy, we have to talk about it one day!). And the females? Well, they have no choice. Or, to be precise, they have the choice of letting jerk males impregnate them or being the last generation with a picky partner choice... So they adapt. Female bed bugs actually have a receptive organ that allows them to survive the sex stabbing.
But nature wouldn't be nature if it couldn't top the bizarreness of traumatic insemination. Some flat worms do have a syringe penis used to inject sperm into their partners but they also are hermaphrodites. So when two meet - penis fencing! And yes, that's the term scientists use. There are two worms, fencing with their penises and the one that gets stabbed first acts as the female. And while that sounds kind of fair, it still sounds kind of bad. However, if the worms don't find a partner, they actually have sex with themselves. And where do you stab a syringe penis on your tail in self-insemination? Exactly, into the only body part you can reach - the head.
So the next time you wonder what the most extreme form of masturbation is - remember: It's self-penis-stabbing-into-the head...
