Great topic. I'd be interested to know how it goes for you. I have a high pain tolerance too. But certain things, like a smack to the face triggers anger, even if someone is just playing around. So far I've only been whipped with suede floggers. The kind that has been used on me are more sensual than what I'd expect from a single tail. Out of curiosity, is the dom you are seeing new? I'd expect a professional to have experience with most whips.
