I recommend you spend some time around intact male equines to become familiar with them. An equine is NOT like a canine, one is a prey animal, the other a predator. Many/most equines view humans as predators so it's VERY important to learn how to speak equine and act less like a predator. Any individual's behavior, including an intact male equine, varies. Some are easy and gentle while others are rough and even savage. If you are considering an intact male equine as a sexual partner I encourage you to focus on a miniature or SMALL pony, NOT a full-sized horse. Keep in mind there are male donkeys and mules. I can't emphasize strongly enough the importance of getting to know a species and individuals prior to attempting any form of 'intimate' contact/relationship with them!
