I'm pissed at my girlfriend at the moment, and I have something to say to you.
What do you want to say?
I heard you like to see me down on my knees, I'd prefer if you watch me cum.
It is rude to preposition another person. You have a girlfriend and you should be faithful even if you are mad.
It's fine. Whenever she gets mad, I'm just going to talk to people and proposition them for sex. I wanted to see how you would react.
Are you just trying to upset her even more? The logic here is completely backwards and as a person in a relationship you should know that you shouldn't talk sexually to other people. Talk to her when she's mad so you can understand why instead.
