Do you have any suggestions on organisations/websites on learning more about sex work created by sex workers? I’m having a discussion with someone who sees all sex work as being essentially the same industry and sees little difference between trafficking and someone who choose to be a sex worker? (sorry if you get this a lot, you have a very educational tag on sex work)

Organizations by sex workers tend to be national, since they focus on challenging national laws, so for things specific to your country you should probably do some research. In the Netherlands there’s Proud. https://wijzijnproud.nl/

If you can at any point take that person to see The Sex Workers Opera in the UK, that’s the best education ever. They have a resources page: https://sexworkersopera.com/learning/stories

But I’d also look at what is holding this person back. Is it really a lack of access to facts and resources? Or is it a moral panic about selling sex? You could waste a lot of time exhausting yourself, serving up facts, for someone who is never going to listen because they’re unwilling to see sex outside of their hyper-moralized framework.
