Homo or Brotherly love in Cry Game

When the black man is captured and bought into a private area, he is tied up and bagged up in the face.  The long hair Irish man is the only face who the black man saw.  The black man begs for the lift of the bag covering his face, but the long hair Irish guy said no.  When the black man needed to take a leak, he took a leak, but he couldn’t stick back his genitals back in.  He asked the Irish man to stick it back in.  At this point, I’m thinking what’s going on?  I would never do that.  In another scene, they emphasized the black man lips while he was smoking.  It show signs of eroticism.  During the black man’s attempt to escape, the white man had the opportunity to shoot him, but he chosed not to.  I believe he would rather see him run and escape then just die in his own hand.  I’m not sure if this is homoly erotic or is this a brotherly thing, because he meets up and hooks up with the girl in the picture.
