Horrible Sex Buddies

My friend is quite cocky of himself when it comes to sex. He says hes a good fuck buddy. At this time, I disagree. It seems like he only cares about his pleasure. I never reached orgasm because he'd always cum so quick & we dont have enough time. I also don't have much experience with sex, but I want to better our experience. I was thinking of talking with him about it or give him hints. Like ask him when we're about to plug it in, "Can you try to last longer" or tell him to not just focus on his orgasm. IDK what else I can do. Please help.
