Not saying human copulation is short, but… there’s no bone in your boner, friend. 
There is a LOT of debate about why genital structures are so varied among species. SO MUCH DRAMA. 
I’m guessing they pheromones to find their mates, but I like to imagine a large rock covered in barnacles, little penises emerging from all of them, feeling around like long thin little fingers. 
What I want to know is if this makes them swim around in circles. 
I recommend watching some youtube videos about this, because those penises are out there, waving around like giant snakes. 
I found conflicting diagrams, both from published books, on whether the fertilizing clasper is anterior or posterior to the spiny knob clasper. It might vary between species. 
I’ve gotten conflicting info on whether or not the males desiccate only leaving their gonads behind or whether they actually thrive better than free-living males. 
So many limbs, so little anything else 
The female is hanging from a leaf. The male is hanging on with his penis I guess? 
Still a better love story than Twilight.
