You asked the question in English, but I would just like to add that, when it comes to education and prevention, a sex worker has to build their character. I am personally a big believer in peer education. I am currently working at AIDS Vancouver Island with people who have substance abuse issues. We are involved in what we call “street college”, which is a form of education provided by peers. I think that helps get the message across.
In schools, I have also delivered workshops on stigmatization, sex work and the understanding of the distinction between having and not having a choice.
I think this approach works. Peer education is very important. It makes it easier to establish a relationship with a young person who wants to go into sex work and explain to them what the consequences, risks and stigma involved are. If she then chooses to become a prostitute, she will at least know what the risks are, while also knowing that she can count on peers.
