the female's phallus
The female spotted hyena has an enlarged clitoris around seventeen centimetres long, externally almost indistinguishable from the male's penis, and a fused false scrotum. She has no external vaginal opening. Urination, copulation and birth all happen through the phallus.
It makes mating physically impossible without her cooperation — the male cannot achieve anything by force — and it makes first births dangerous: the canal tears, and a substantial share of firstborn cubs do not survive. Spotted hyena clans are female-dominated, and the anatomy is thought to be a side effect of the androgen levels that come with it.
Did you know
Early naturalists concluded from the anatomy that hyenas were hermaphrodites that changed sex each year. Aristotle dismissed the claim in the fourth century BC after examining one, and the belief persisted for another two thousand years regardless.
The sex-toy guide
A shop has two hundred of them. One of them is right for you.
Seven questions: who it is for, what sounds appealing, how quiet it has to be, what it may cost. Out comes one type — with what to look for, what it costs, and what nobody prints on the box.
Sixteen types, from a bullet vibrator to a blindfold
No brands, no shop, nothing for sale here

For the two of you
Find out what you both want — without either of you saying it first.
You each answer twenty questions on your own, and neither of you ever sees the other’s answers. Only what you both said yes or maybe to comes back. A no and a maybe look identical from outside, so saying no costs nothing — which is what makes the answers honest.
