As someone who took the "no kink" at the start here is my experience. I got into this relationship, initially just as progression of a close friendship. Bondage and even sex were the farthest things from my mind. I have been lucky enough to find an open minded partner. If I were to do it again though, it would probably wouldn't be a deal breaker. Bondage for me, is a physical interest. At the end of the day, I want to be with someone I enjoy on more than a physical level. If we don't share a kink, that is a small thing to me, like having different tastes in music.
