    en.wikipedia.org/wiki/Penile_spines

    Felines, especially domestic cats, are well known for having penile spines. Upon withdrawal of a cat's penis, the spines rake the walls of the female's vagina, which may serve as a trigger for ovulation. [4] [5] Many other felid species have penile spines, but they are relatively small in jaguars and pumas, and do not occur in margays. [6]

The corresponding system in females is the female reproductive system.

    The penis sheath of a male axis deer is elongated and urine-stained. When rubbing trees with their horns, these stags sometimes move the penis back and forth rapidly inside its sheath. [10] Male bison and fallow deer have tufts of fur at the end of their penis sheaths. [11] In rodents, the length of the prepuce is related to urine marking ...
