For me, it's the thrill of having so much of my body inside another. So getting up to my shoulder is the biggest thrill I can experience. The depth is also a big thing. So for example, if I fisted an elephant, I'd get the pleasure of having so much of my body experiencing the warmth and softness, but I wouldn't get the intimacy of feeling the deeper, almost inaccessible parts of the body that I could reach in a horse. That's why I can't wait to fist a dog. In a horse, I only got part of my forearm past the rectum. In a dog, I could probably unravel the whole large intestine.
