I think the idea was that it pisses her off so she tries to humiliate you? I mean, I know there are people that enjoy dick stomping, but most people probably find it humiliating.
As for the rest of the scenes... I guess making you a sub is humiliating? Again, a lot of people actually enjoy it, but even they don't necessarily want it publicly.
Or, since her motivation for underground fights is her stress/frustration, hate fucking someone who pissed her off may be helping her release stress?
Confirmed, you're right - you don't have to make her cum in touch mode, only max out her arousal.
The double front kick - you can interrupt between kicks.
