People say jobs like prostitution can involve exploitation. And sometimes that is true. But sex workers in places like western European have rights and benefits that rival the best America jobs. And in places like Amsterdam pandering is illegal.
Just because it is illegal doesn't mean it doesn't happen. Most are in a very vulnerable situation. Most it is a last resort. Notice I used the word "most" I also feel if the "customer" feels the need to have sex this way they need to do some serious soul searching why! I am fully against any situation where someone is giving something for sex. Yes even in a marriage this can happen and does!
