bull has dominance?

Hi all, my girlfriend is cucking me and has been for bout a year now. She is 23 and I'm 27 and her bull is 24. He really asserts his dominance over me by giving me orders making me pay for all of us if we go out and will punish me if I am bad. My girlfriend does this also but he has almost taken what I would describe as a stern disciplinarian role. Does anyone else have this kind of arrangement. It is most exciting because he is younger than I am
