Whatever floats your boat my friendI'm sure Mistress 4u is as good as you say but I have given a commitment. You see when I begged my Mistress to allow me to become her slave I really wanted to be her slave. I feel that you can only have one Mistress, so when I was accepted as her slave I had totally submitted to her. As another way to prove my submission I chose not to see any other escorts no matter how tempting they maybe. I have seen many escorts but my Mistress was the only one that I really wanted to be her slave. I cannot be a slave for a couple of hours during a session and then leave and see some other escort, that's not right. If you are just a sub well that's fine but if you are a slave then you must be loyal. It helps with being submissive as you must always deny temptation and be loyal so you are always in role. I will admit that I have been tempted by some escorts profiles and pics( not many but maybe 2 or 3 ) but I will not give in as when I see my Mistress it is totally worth the denial. Even though you say I am missing out really I am not. I am lucky to be allowed to serve a beautiful Mistress and I will only treat her with total respect, so when I tell my Mistress that I will do something then I will do it. In these relationships as consenting adults there really is no hold over each other only what each wants it to be. But I feel myself that I must be totally loyal to my Mistress and this helps satisfy my need to serve a beautiful woman and to make her life some bit easier when I am requested to do so. So as I said I really am not missing out on anything, in fact my situation is something I have only dreamed about but now is a reality and its good.
I don't mean to dismiss your suggestion, in fact thanks for it but I cannot act on it. Above are the reasons why.
