Do you really expect someone to just rush into a s/m relationship with you and do literally everything you say when they don't even know you? Why should any slave or sub do what you say? What are you offering in return for their obedience? Are you willing to look after them? Do you plan to really get to know them on a personal level? Will you do things to ensure that they enjoy themselves as well, or do you really think it's all about you? Slaves, submissives, or anyone else in this category are not your personal sex toys. You can't just be like "i need someone to do whatever i say all the time from the moment we start talking" and expect good results. Real BDSM relationships are built on trust, more than anything, and you haven't offered a reason for anyone to give you that.
