At that point, it's not your job to teach them on the social norm, it's your job to understand their pov, and explain yours so you can negotiate a win-win situation between the two of you, which will make you both happy. Otherwise, you are oppressing them, and using the 'because the majority says it's gotto be this way!' thing just to get your way. You talk about caring for the feelings of others..what others? It's just you and him in that situation and you sure as hell aint caring about his feelings. Only yours left. How's that not selfish?
