We have a pushing 10 month old bull. He has been trying to mount some of our cows which is not my concern. My concern is I have never noticed his penis come out of his sheath. There's no swelling or apparent injury or discomfort that I can tell. Is this a problem and if so what might it be? I've not made it a point to intently watch to make sure this is the case but have seen him mount a dozen times or so and either he retracts very quick or never extends to start. Any help is appreciated.
