What is the length and diameter of a donkey penis?

The average length of a donkey's penis is typically around 15 to 20 inches (38 to 51 cm) when fully extended, with a diameter of approximately 1 to 2 inches (2.5 to 5 cm). However, there can be variations depending on the individual animal. Donkeys, like many other animals, have anatomical differences that can affect size.
