US PROS Collective
The US PROStitutes Collective (US PROS) is a multiracial network of women who work or have worked in different areas of the sex industry. Founded in 1982, US PROS campaigns for the decriminalization of prostitution and for justice, protection and resources so that no woman, young person or man is forced into prostitution through poverty or violence.
