I don't want to have sex with him anymore because

My boyfriend only cares about getting his nut in and that's it. Literally last about 2 minutes, nuts, rolls over, and falls asleep. I told him he doesn't get anymore cat cause he's so damn selfish when it comes to sex. I want to have sex with him but than I have to remind myself that I'm not gonna get anything out of it anyway.... Rant over.
