Cuming to quick

Hey ladies I have a problem.My bf is not circumcised and he always nuts fast like 3 pumps and hes done.🤦🏽‍♀️ At this point I dont know what to do.He says his penis is really sensitive because he is not circumcised.He is a good guy and we have 2 kids together but Im just not satisfied sex wise and its making me very frustrated that we have been arguing alot lately.Please give me advice on what to do
