HAHAHA that is pure rediculousness, absolutely nonsense, prostitution is illegal, sand furthermore, if you pay someone for sexual favors whether it be male or female, you cannot unpay them, when the money hits there hands its theres 100 percent, so no you cannot sue someone for not complying with your sexual gratisfication. there is such force that could be taken in action that would be called RAPE!! this of course is WRONG! pure insanity if you ask me. but if she choses to take your money and then walk away all you can really do here is walk away and try again, or learn from the situation and not buy sex from men or woman whom ever you prefer.
