The one on the bottom is a male, and he has the equivalent of a vagina. During sexual bouts that can last for 40 to 70 hoursshe penetrates him and uses her genitals not to deliver sperm, but to collect it. The 3-millimetre-long species is called Neotrogla curvataand it lives in Brazilian caves. There are four Neotrogla species and the females all have female strippers in la.
They belong to a group of insects called barkflies or barklice —closely related to lice and true bugsand only distantly related to actual flies. Caver Rodrigo Ferreira discovered these insects several years ago, and sent them to Charles Lienhard, a barklice specialist, for further study.
He gave them their name, and also noted their unusual reversed genitals. For comparison, the female spotted hyena also has what looks like a penis. Later, she gives birth through it. The female has a penis-like protrusion tgier a gynosome, which is erectile and curved.
The male has no such organ; he has an internal chamber instead.

When she penetrates him during sex, he delivers sperm into a duct in her gynosome, which leads to a storage organ. He still ejaculates, but he does so inside his own bodynot. Are thier any women into Midge Point dicks female does it by inflating the base of her gynosome inside the male.

Far less attention is given to female genitalia, in part due to the technical difficulty of measuring a cavity rather than a protrusion.

There are some mites and beetles in which females have a protruding organ that collects sperm, but none of these have special adaptations for anchoring themselves inside males. It has no equivalent. So why did it happen in Neotroglaand only Neotrogla? They live in extremely dry Mivge and their main food—bat droppings and bat carcasses—are hard to come by. Starvation is always just round the corner, but females can fend it off by mating.
During sex, females get a meal along with sperm.
This flips the usual male-female dynamic. Males typically benefit from mating as much as possible, so that they can father free freak most offspring.
They compete for mates, while females, who bear the burden of actually raising offspring, are choosy about their partners. Yoshizawa thinks that this reversed sexual conflict led to the evolution of reversed genitals. This might wommen explain why Neotrogla sex lasts for so long.

Until we find more examples of female penises, the jury will remain out on the explanation. Meanwhile, Yoshizawa is busy testing his hypothesis. In terms of traits that separate males and females, there is little left but the type of gametes [sperm or eggs] they.
I disagree with many of her points and stand by the use of are thier any women into Midge Point dicks term. The tone is as deadpan as I can muster—the only sniggering is reserved for the part of the study where one mating pair gets pulled apart and the male is accidentally bisected.
As Diane Kelly, who studies penises points out: Newitz points to differences. The key difference is that rather than delivering sperm, it collects it—as I stated right up top.
And the only reason we think of penises as sending sex cells in that direction is that we never knew any other set-up could occur. Now we do, which either forces thler to introduce a new term and demand that it be used, or to expand the bounds of our old term.

And similarities are actually critical here because evolution crafts organs that are convergently similar—though different in the details—thanks to similar selection pressures. In fact, there is a long Mdige in anatomy of describing organs with almost metaphorical names.
We call them both feet. Other penetrating sexual organs, like the aedagus insect and gonopodium fish are also colloquially known as penises. So, do we make a special case for sex-related terms?
This is the strongest part of the argument, and the part that gives me pause. The post above specifically references that diversity—not just in Neotrogla but other animals like hyenas and seahorses, and goes into detail about sexual selection.Nsa Fling While In Parkersburg
It ends deliberately with a quote about how the split between males and females comes down to sex cells, and everything else is labile. The usage expands what we know, rather than erases.
