For me, FNIT was more about pure lust. The SNIT was as much about love as it was sex, IMO. I think this progression is good as it is. And by "mother and child", I did not mean it was something about family relations; it was more about Jack being protective about Ennis, as a mother who reassures a scared and uncertain child.
In FNIT I also see a lot of their love and connection, I see Jack consoling Ennis, waiting until he's calmed down after the first shock (

), trying to caress his face, and Ennis who is firstly defendind by grabbing Jack's shirt, later also touches his face with love and sensual expectations... they had it all there, it was just not so open as neither of them (particularly Ennis) had no courage to put 2 and 2 together. (Unfortunately, the same bad math in the future years cost them a whole beautiful world of sweet life...)

But IMO, even it was the pure lust, the feelings were there, very visible IMO.
As for SNIT, well - there are often 2 sides in a relationship, one braver, seducing and comforting, and the other one - shy follower, who need encouragement and consolation. In SNIT was more than obvious who's who!

Amazingly, the whole package - their emotions and their physical experience J&H perfectly passed to the viewers. I already said this: I felt like I was there in the tent, that miraculous it was!
