For those of you who are bothered by BDSM you have to understand the people doing these things actually really care about each other.
In fact, I feel every owner loves their pet and every master loves their slave. These kinds of relationships require the utmost respect, communication, and control.
Knife play specifically does not have to draw blood. I had to get my back glued because my partner cut too deep, but he was trying for me, and I love for him for it. Knife play is not always about cutting, that is only for some people. If you want to try it, I encourage you to trace your body with the blade before someone else’s, send yourself and him/her shivers before scars. If you do cut too deep, GET IT CLEANED AND SEALED. Please stop spreading negative images or misconceptions of BDSM. Unlike a lot of sex trends, it is a very welcoming and loving community who NEVER force anything unpredictable upon their partners. In fact I think people experienced in BDSM are the best mates.
