I'm undecided about the sex discussion. On the one hand, I think it's nice that we see it at a romantic level, arms round each other, talking intimately. But some of the things that are said in that discussion make Ennis seem so much more open and really show his feelings for Jack.
Thanks for clarifying the wording there, don't have my SP handy, memory ain't what it was in my daddy's day.

This is a connundrum, for sure, huh?
I honestly try not to compare the SS to the SP or film too much, since we all agree they are each masterpieces in their own right, and have maybe slightly different slants, whatever; although using bits and pieces from one to clarify the other works often. Plus, notice how I mess up the words if I don't have my cheat sheet, lol.

I love each incarnatin for it's own unique vision (granting all praise to Annie for creating the original form from which all Brokeback goodness stems!).
I admit that the vision I most strongly gravitate to is the film, and most of my attention goes to it for that reason, I think. So regarding this motel sex discussion, "Film" Ennis seems to be even more repressed than "SS" Ennis (who would have believed it possible!!), at least verbally, so I guess I find it hard to imagine him putting into words the physicality of his relationship with Jack.(??) Since he keeps referring to it as "thing" or "this thing" and all. Much as we'd like to hear them both give voice to their feelings more freely, darn it ...
I actually love how because they are given fewer words in places they instead have to speak with their eyes, touches, bodie, actions - and that we get to "feel" their emotions with them this way.

SNIT being just one very fine example of that tradeoff.

In particular, I'm thinking about the bit where he tells Jack about the gut cramps - hinting that if he'd realised sooner what he was feeling then things might have been different. Ah, I dunno...
Yeah, it would have been sweet if Ennis had admitted that to Jack, wouldn't it? I think Jack would have been stunned to know Ennis had felt so strongly all those years back ... although then he might have really started thinking about all the lost time, the what if's ...
Ah, I dunno, either, I guess. :-\
Maybe virtually ignoring those lost four years, summing them up with few words, was a way both men could show their love to the other. They hadn't been together, so those times have no place in the relationship they were going to build going forward.
Now I'm just confusing myself ...

not hard to do!
