No, but I have milked goats. Same thing only smaller. I had neighbors that raised dairy goats and it was so fun to milk and help with bottle feeding babies. I have also cleaned a horses penis sheath…luckily he was a mellow horse, a lot of horses do not want anyone pulling back their foreskin to clean out the debris. lol A lot of people don;t know that geldings as well as stallions need their sheaths periodically cleaned. They pick up all sorts of irritants and an irritated penis is, well…unhappy. haha
