Would you be mad?

Ladies, would you be mad if your SO didn't care about pleasing you just himself? Mine literally fucks me whenever HE wants and says no to me whenever I want it. And whenever he gets it he stops pleasing me after he cums which is like within 3 minutes & doesn't even care to finish me off knowing I didn't have my orgasm. I'm getting frustrated and he says I'm acting like a child over it and that I'm making shit up just to start shit. Keep in mind that we're both young, we're 20 and we only have sex once a week. Am I overreacting? Or would you ladies be frustrated too??
