Here is Mr. Jazz. He is my baby! I've just been out to see him. I've had him for 11 years and love him more each year!
Seriously though, be careful. You're an adult and you have the right to do whatever you want. It looks like you and Benny have a lot of fun together. For my first 5-7 years in horses I did a lot of things I look back at and sigh. I rode horses that were barely broke and dead crazy to boot. I galloped through pastures in halter and leadrope. I laid down in stalls with the horses. I laid down in front of them. I talked on my cell phone while riding, at the trot and canter. Many of these things Jazz and I did together. Somehow I was never hurt, but looking back I'd never do most of it again. It wasn't worth the risk just to have a laugh and say I'd been there done that. Benny is very kind by the looks of it, but he's still a horse. Something could come up behind him and spook him, and immediately he'd take action and move forward. When herd animals stampede they often kill many of their own - it's what they do: run first, ask questions later. Taking a little extra precaution with Benny today could very well be what gives you the chance to enjoy him tomorrow.
Trust me, it's not worth it. Have a good time, but take care. Though I was never injured, I've seen very good friends of mine be gravely injured, and knew of a girl that was killed because she was too proud to listen to what those around her were telling her. A bit of a laugh isn't worth that risk.
I'm sorry that things got heated and offensive, and in my opinion that wasn't the way to approach the topic. I'm hoping though that this didn't make you sour on the subject and close your mind. Please be careful, and enjoy that lovely horse of yours!
