Just my general quest for accuracy in my regular dino drawings. Allready a few dino-mating drawings out there, but prefering the more whimsical approach, I'm drawing a pig-like dino chase another, penis out, inspired by penis-chase situations I've seen with ducks. Some animals are pretty rapey, luckily, the females tend to be pretty kicky to compensate for it.
It's strange. Mooost animals tend to gravitate towards willful copulation, but to many animals it seems like a very tense thing. Big felines females, lions, tigers, jaguars, tend to let the male go ahead - but quickly turns it rough, with a lot of growly bity intercourse. Some animals, among them a few birds, seem to force themselves through it. Not to mention a lot of arthropods.
