The Reward Foundation supports the work of the National Center on Sexual Exploitation (NCOSE) in the US. They have produced an excellent summary of research about the sexual exploitation of men and boys called Out of the Shadows.
Here is an excerpt from the Introduction.
“Often overlooked, the sexual abuse and exploitation of boys and men is a long-neglected, festering national problem. Yet, every day males are sexually objectified; sexually abused as children; sexually assaulted as adults; used in the production of and harmed by the use of pornography; exploited in prostitution; and sexually trafficked to feed the global supply chain of sexual exploitation (i.e., the global sex industry).
Because society frequently views sexual abuse and exploitation as phenomena exclusively affecting females, male victims of sexual trauma go unidentified, their pain and suffering unattended, their victimization unrecognized by the world around them. This must stop. Sexual abuse and exploitation are unacceptable violations of human dignity irrespective of one’s sex.
For this reason the National Center on Sexual Exploitation is working to bring issues related to the sexual abuse and exploitation of men and boys out of the shadows. As a part of this effort we have begun compiling research findings documenting the harms experienced by boys and men across the expansive web of sexual abuse and exploitation. The information assembled here marks the beginning of what will be our ongoing effort to shine a much-needed spotlight on and elevate the discourse about the sexual abuse and exploitation of males. Please check the NCOSE webpage periodically for updates to this document.”
