Starting a new thread as a support thread was getting derailed.
It's a simple proposition - sex that a woman doesn't want is rape. Paid sex is unwanted sex, thus rape.
The idea that prostitution can merely be a transaction like any other customer service, comes from men. A woman-centred approach understands the unique experience of having another person's body parts inside your body, how intimate that is, and how violating it is if it's unwanted.
Men have created a world where women very often don't have direct access to resources we're entitled to. Thus they are able to manipulate and control women's behaviour by offering resources in return for being able to sexually harm us. A world in which women were equal in resources to men would be a world without prostitution. It's never a woman's choice, it's a man's choice.
