I think that it may be possible that a female US agent ( FBI or CIA or Militay Intelegence ) may torture muslim prisoners by removing their clothes, touching them, showing them ponographic movies and causing them pain or itching to get them to confess. Muslim men may engage in sex acts with women that they are not married to when they are away in public, but they will not admit to that when they are with friends or family. So to have a female agent touch them or arouse them in front of other muslims is a great humiliation, especialy when they are tied down and could do nothing about it.
I do not believe that the female agents have sex with the prisoners as a method to obtain a confession.
