and yes, I thought about that a bit after reading further myself, but I'd honestly still say that was less of a fight and more her one sidedly being stubborn after a while. The initial "fight" was basically all in that one part, but she doubled down on not listening to him and then kept seeming like even she felt she was in the wrong for doing so, but didn't really know how to get herself out of that spot.
As for this part, again, I just don't see what you do. He never said a single thing that gave me the impression he "just" wants some porn like experience. He did fall for the trap of acting the way he saw in porn, but if anything his only intention there was "this seems to work for both parties involved from what I can see." He just earnestly seemed bummed that she wasn't also enjoying their time together, rather than bummed that he wasn't fulfilling his own fantasies. Even his comment that sounded really bad about how she was basically just a sex toy, he was saying that because he thought it was not the right state for things to be in, and wanted to change that.
