What Turns You Off?

I had this thought while watching porn and the top slapped the bottom a couple times and the bottom grabbed his arm and kept it there, so as to not keep getting slapped. At this point I laughed a bit, which killed my hard on and went "uh, no," proceeding to click off the video.I just thought it was really awkward for everyone involved (including myself) and was rather baffled that they didn't set up two people who weren't into the same stuff.So what kind of "kinks" are you folks into? I really like to get my ass manhandled (both figuratively and literally); a lot of grabbing and slapping. But Im also into uniforms. Gets me going.
