Here in the USA, we call a hotel where you can park your "motor car" right outside of the front door a "motel." That's "motor hotel" shortened to one word. The place was called the "Motel Siesta."
In the book, after Jack and Ennis trade places, and Ennis actually gets to work while riding his horse with the sheep, Ennis begins to have a change in his own self-esteem.
Ennis felt that he had accomplished something when the first thing he told Jack when he came down from above to the camp platform was that he had killed a coyote at first light. Ennis' spirit is that of one who is a protector. After he shaves, Ennis strips off in front of the campfire (Jack notices that Ennis wears no underwear nor socks) and warshes everything he can reach while Jack is peeling potatoes. And after supper, Ennis opens up to Jack about his life before Brokeback. And, Jack shares his own experiences, too.
That evening together where Jack and Ennis respected each other's opinions moved Ennis' self-esteem up several notches. That's why he felt like he could paw the white out of the moon when he was riding back up to spend the night with the sheep.
It could have been love at first sight for Jack Twist; but, with Ennis, the friendship which developed over time turned into his being in love with Jack. I think that the "dozy embrace" flashback where a sexless hunger was satisfied took place during their developing friendship before the first night in the tent. I feel that Jack had a need of natural affection from another man as to fill a emptiness for companionship and that Ennis took care of doing that in his sorta mothering Jack by holding him behind. I only use "mothering" here because Ennis apparently never got hugs and kisses or was even held by his own father before his father died.
While my situation with Ed Pursell was not quite like that of Jack and Ennis, I believe that Ed was in love with me from the beginning of our first night together. I moved in with him 10 days after that. I loved Ed as a friend and it felt like being with family in his presence. But, we were together for a while before I realized that I was in love with him and said to myself, "I want to spend the rest of my life with this man."
And, I had that thought one evening when Ed was fixing something to eat and I was standing in the kitchen talking to him. We had talks like I had with my mother in the kitchen at home.
