I think hard limits are very personal in nature. Each person develops their own tastes in life, and I think that leads to those things which they find are impossible to do.

I think some people have limits which relate to one of their five senses. Certainly, most of us in this forum are testing tactile limits (such as whips, cbt, slapping, etc.). But taste and smell are also senses. If J's blu has developed senses that are abhorrent to her, then so be it. She should be able to define her own hard limits, rather than attempt to, and have someone say, "Oh we don't recognize that limit, so it doesn't count."
