Seriously, just get a horse dildo instead of sexually abusing animals.

If you've ever actually been around horses, you would know that in the case of horses at least, you are in far more danger than them. I've nearly been crushed by mares in estrus or tackled and bit hard enough to draw blood and create massive bruises by randy young stallions. They are horny monsters and can kill you accidentally with ease.

Also, if you've been around real horses you should quickly lose whatever kinks or desires you think you have. They're horrifying animals and they fart louder than lawnmower engines and tend to create pools of urine and feces that will make your eyes water and burn your lungs with the amount of ammonia they produce.

edit: here is a video of an absurdly expensive friesian stallion, the very same kind I used to tend, getting killed from one casual kick with from a mare who wasn't in the mood. Obviously, if you don't like seeing animals die this clip is extremely NSFL, and NSFW because of visible horsedick.

Yes, this is human failure that led to this, but I think it should be a warning to people who think these are beautiful, magical, "sexy" creatures who won't mind if you jump a fence to fool around with them. Do not fucking fuck with horses. You will die and have a very embarrassing obituary.
