How rough do you like it?

As some of you may know I am pretty much a sexual submissive and enjoy many elements of the BDSM lifestyle. Not all BDSM is whips and chains or degredation of the like and chances are the sex you have will have aspects of it as well. So, I'm just curious as to what are your preferences and what is the most extreme thing you would like to experience sexually? Don't worry about me judging. Just because I am not into it doesn't mean I will think any less of you. We should all feel good with our appetites.
