Loving the choices this boy has to make.  There's one obvious piece missing though - his tits.  Clamps should be applied to those lovely nipples and then each one tied back up to the cross beam with just enough tension to be felt.  Oh, but now if the boy lowers himself to relieve his balls, besides being impaled further, those tits would be pulled much more and he would have to deal with that.  Tough decisions for the poor boy.
