This scene from The Piano: m.youtube.com/watch?v=GPDwOGyqRwc
And this description, beautifully written (as is the whole book), so that it’s a love scene as much as a sex scene, from the novella Brokeback Mountain:
“They seized each other by the shoulders, hugged mightily, squeezing the breath out of each other, saying, son of a bitch, son of a bitch, then, and easily as the right key turns the lock tumblers, their mouths came together, and hard, Jack’s big teeth bringing blood, his hat falling to the floor, stubble rasping, wet saliva welling, and the door opening and Alma looking out for a few seconds at Ennis’s straining shoulders and shutting the door again and still they clinched, pressing chest and groin and thigh and leg together, treading on each other’s toes until they pulled apart to breathe and Ennis, not big on endearments, said what he said to his horses and his daughters, little darlin.”
