I consider myself to be sensitive, but not delicate. I have found a direct correlation between how much roughness I enjoy and my level of arousal. I don't care to be man-handled roughly at the beginning, when we first start. I like for it to build as the level of arousal goes up. When fully aroused, my body is happy to be grabbed, pounded, man-handled or squeezed

That being said, it's a fine line between pleasure and pain and everyone draws that line in a different place. It's not a matter of adequate or inadequate, it's a preference and no more than that, like enjoying anal or oral. Some like it and some don't, that's what makes the world go 'round, right?
