Wow ! this 6 channel stereo sounds like something worth checking out. I've never heard of this. I'll be checking my own remote for this feature. But......
I have a very ...ahem...delicate question to ask about Jack's *preparedness* in FNIT.
Jack began the encounter. Here goes. Did he realize at the time that they didn't have any kind of lube? was he expecting it to go this far? Didn't this hurt? Just curious?
I watched the movie with someone who at the moment of penetration shouted " No way Man!! that could not happen without the proper lube! Spit just is not enough! Don't they have Crisco or something?!!!
Needless to say, my friend found the scene * unbelievable*, I found it totally erotic. Please inform. 
For the 6 channel stereo, this is the brand and model #, as it is written across the front of the receiver:
Yamaha natural sound av receiver Rx v630.
Mine is about four or five years old, so there's no telling if they still make this model, but you can ask for the feature.
Part 2: Personally speaking, that kind of ride being pleasurable or not depends not just on lube, but also on one's desire for the boatman, the boatman's talent, and/or (for the urban sophisticates among us) the boatman's oar. Just like everything, I'd imagine it really depends on how much you are into it. I also cringed with the "spit and slick": not on Ennis's first time - in the real world, they would have both been in pain and had a great potential even for skin tears, but for two straight guys, they did it well, I so whole-heartedly didn't mind being aware that I was watching two pretend straight boys in love and heat for one another so bad they couldn't stand it no more - they could do nothing but fix it. Enough lube or not, it just does not matter. They are so Ennis and Jack, just foolin' around and fallin' in love...
But, on a truly worrisome note, I am so afraid Ennis's pants/zipper weren't/wasn't down far enough - I felt a lot of things in this movie vicariously, including this pain: that scraping chafe on the hanging bits from that damn zipper. Yes, said the voice of experience, but only once, and it's not the sort of thing you casually permit a repeat.
You can be in too much of a hurry and wind up being distractingly "irritated" for days.
