Aww ur bf totally reminds me of what mine would do, but he probably wouldn't want the horse to trot, lol. I think I've had him on a horse once and it was at rodeo, at night. We were going to bring the horses for water I think so I jumped on Shadow and then he really wanted to ride so I got off and helped him get on bareback mind you! And then I got on infront of him. We did a bit of riding and I had to pee so while I went he stayed on. When I got back he was like I turned him!
Omg he was so excited and I used my cheriest voice and was like good job hunny that's awsome! (not use to congradulating someone for that lol). But he just seemed so happy.
The next day I was talking about it to someone while he was with me and I was telling them how he got on the horse bareback. He was like that's unusual for the first time? I was umm yea because most people want the security of a saddle.. haha.
Some backround info.. He use to be terrified of horses. He said once he got chased through a field by them at night. I got him to step in a pen with them for the first time since it had happened. The next day after he rode were all of the events. He helped alot, with holding horse's to helping with my coach's riding kids to help hold random things haha. It was awsome and I'm proud of him.
As for sticking him on my horse.. I might wanna put him on one of my coach's lesson horse's first haha. Just cause she's so young yet. I think if he fell off he'd never get back on.
Sorry for the rant.. haha just thought it was exciting too see other people doing it too!
