I've decided to visit an escort

Ok I want to start this thread by saying I have made a personal choice to visit an escort I am not looking for people here telling me not to do it based on their own moral viewpoint

What I would like to know what are the legal issues surrounding this I have heard everything from its 100% legal to visit a girl in her own premises as long as she is working alone as more than one constitutes a brothel but I have also heard that even though its legal the gards prey on peoples ignorance of the law other things I have heard is that its all illegal and thats why escorts advertise you are paying for their time only and anything that happens between 2 consenting adults is their business

Can someone tell me what the situation really is?
