I think of the motel scene, Ennis laying on Jack. Jack's arm around him as Ennis caresses it. any barriers Ennis had were dropped. Ennis in a vulnerable state thinking a simple punch ended it, and Jack thinking brokeback was alive again, and got them good. It was all mental and emotional after that. The pull these two had for each other, and then yanking it away, it amazes me that they could keep this up for twenty years. And without one or the other going nuts, or one killing the other. This was their life, and what kept them alive. It took fate to end it, a bad tire, or a mob take your pick. It went so far beyond the sex act, or how many times they got to do it. jmo.
