I don't have any advice however your post made me smile and warmed my heart.

Sir takes into account the limitations I have due to severe nerve damage. Although I'm mostly a "good girl" , He makes sure when it's time for correction or discipline that it won't negatively affect my health.

I've only been punished once and it involved humiliation (which totally isn't my kink). That was more than enough to keep me on the straight and narrow.
