I know we have at least one Mistress among us, and maybe she can help me out.

My gf has the dark and deep desires to dominate someone. On the other hand, she loves me enough and thinks that if she really shows her deep dark and bad side, that I will get scared and wont want to be with her. Now this isnt the case, but I really dont have any desire to live in that sort of relationship. However, It might be interesting to try it out during lovemaking. Can you give me some pointers and advice on how to handle this situation. I have a slight idea of how it works, but im not sure what I need to do to protect myself, and her from cross a line. I really have no desire to suffer pain or humiliation, but I wouldnt mind giving up control in the bedroom to her if it would bring us more pleasure.
