I am starting to understand TRP and it is starting to make (scary) sense, but I have a question about frame.

So I try to lead with my girlfriend as much as possible, in the bedroom, in life, but I have issues maintaining frame. Like I will tell her to do something and sometimes she gets upset that I don't say please and thank you. Perhaps it is my tone. If I am low key about something and make a logical demand she has no complaints, but lets say I am in the bedroom and I want to suck my dick (which she doesn't mind doing) I say suck my dick, and she gets upset because I don't say something like "please would you suck my dick." Now this doesn't seem very TRP. I don't think she is trying to shit test me, she just grew up in a very polite Southern family. Now maybe I could be more low key about demands, but if I make a demand in the bedroom or out, and she gets upset, how should I keep my frame? If I don't back down then she gets incredibly upset but if I do back down that seems very beta.
