I'm a woman, and I do not agree with your biases. From Oxford definition of slave is "a person who is the legal property of another and is forced to obey them."
Most sex workers are no ones legal property. They signed up for the job volunteerly often to escape poverty. Some do it for the fun. And contrary to your opinion, most of them are educated, maybe not to a university degree.
The slaves are the ones being shipped in from other countries and forced into the job. But majority of sex worker join the industry because they think is the easiest form of earning an income.
I'm surprised you are still living with a man who patronises porn movies despite your disgust for them. Whatever abuses you must have been through isn't more than what most sex workers have been through, so stop with your criticism. I can sense in your tone that you hate them for what they do, not who they are.
