A Dom that Cums Quick

Hey brother Sam,

I’ve recently been serving this dominant guy my age (25), and he uses me so well. I feel naturally submissive around him, and when I don’t he is quick to impose control and I acquiesce.
the thing is, when he fucks me or makes me suck him off before work he cums so fast—like 1-2 minutes. Now, I know that sex isn’t the most important part of submission and has nothing to do with me being fag, but it makes me wonder. I’ve brought this up to my Dom and he says that sex is just a stress relief for him and that he prefers sex to be quick so he can move on to other things.

This feels unfair to me. I want to be pounded relentlessly but it doesn’t seem like he’s interested in that. Is it right for him to be that way, not trying to last longer, and do I just need to submit?
