When I researched about human trafficking, I found masturbation leads to watching porn which leads to seeking escorts. Escorts - leads to human trafficking for where there is demand, there is exploitation. This is not true of all people, but a great portion of those who masturbate, will watch porn, and great amount of those will seek escorts/prostitutes.
What is worse, is when people go that route, some of them begin to get child fetishes. And there human trafficking in that.
I think the two places Quran talks about hijaab and etiquette sexually is Surah Noor and Surah Ahzab. Both these places there is a contrast to those who are forced to prostitution (Surah Noor) and Hijab as distinction from slaves and who aren't free (Surah Ahzab).
Not all escorts and strippers are human trafficked. But how many are, you will get different numbers from "academics" and those who are involved in trying to end human trafficking or help victims of it.
When I saw what Natives say about in North America, it seems they believe politicians are in on it and there is hiding of what is really going on and it's more severe than what they show. Every time there is a case where someone is arrested in these big human exploitation things, they dismiss easily in the media. The Natives see it as ongoing part of exploitation and imperialism.
In Africa, it's even worst, in that there is organ human trafficking. That so far, is not something caught in the west. But who knows if it happens here or not.
