My boyfriend states im the only one he has been with that he cannot control when he's cumming. And he cums too fast. Is there something wrong with me?

For context, my boyfriend is very experienced when it comes to sex. I( 35f) only had 2 ( him and one other ex) he stated, he usually is able to control when he's cumming, so it will be more pleasurable to his partner but not with me. How come I'm the only one he can't control it with? Is there something wrong with me? Is there anything I should do?
