Just out of safety sake... And being involved in the fetish community, as well as having a negative sub experience because I was a little naive, but this could be a very bad idea. The Dom/sub relationship should be built and molded and never follow the infatuation guide of the 50 shades show. I know a man who trained his sub so that she lost weight and if she gained a tenth of a pound she went on a liquid diet. That shows a lack of knowledge on the human body with him, but she was a sub and as a good lil sub she did as she was told. There's a really fine line that this could cross and people can get hurt of they don't know the facts about the Dom/sub world outside of 50 shades, especially with Doms who are willing to take advantage of people who don't know this.
