You know what is also lovely in their intimate scenes - it's how they look at each other (especially Jack), with touching or a little spaced foreheads, holding/caressing each other head...
The most passionate moments were in the FNIT before the sex act, the most emotional moments was after the Ennis's kiss in the reunion scene, and in the SNIT was just the split of the sec in the very end of the scene, when Jack stops kissing Ennis and just lean his forehead on him (mouth open...).
In these scenes Ennis sometimes looks down, but Jack keep his eyes firmly on Ennis.
I've seen this kind of scenes in other movies too, but never so much emphatic, with so many energy and relay of emotions to each other. Who ever thought of it is a genius! I looove that.
I have a feeling as they're making love with their eyes.
PS:

Hm...After someone gives you that kind of look, does he really have to say "I love you" at all??
Isn't it clear like a mountain water?
