That feeling is so rewarding, anytime a man can make me feel weak and vulnerable, even while he's shoving his hard cock in my ass and dumping a load of semen in me....just a great feeling.
I agree. I find it thrilling and satisfying in a strange way. I often think about a time when I got dominated and fucked really hard by a big guy. I was so nervous that penis was limp. It just flopped around while I sat on his cock. Even so the sex was so great. Slightly humiliating, but great.
