Porcupines

The females are only interested in sex around 8-12 hours a year. During the short mating season, the male stands up on his hind legs, waddles up to the female and sprays her with a huge stream of urine from as far as 6 feet away and drenches the lady from head to toe. If she didn’t like it, she screams and shakes it off, but if she’s ready she’ll rear up to expose her underbelly and let the male mount her from behind. Once it gets to this point, the female forces the male to mate constantly until he is thoroughly exhausted.
