Sexy time

Hey y’all. Me and my boyfriend have been together awhile now and we recently began having sex and it’s super great for me I’m very relaxed. But he never cums during sex, I always have to end up giving him head to finish. We’ve talked about it and he says it’s bc im “too wet and too lose” and I don’t think he means it to be mean. Can anyone give me any advice on how I go about this ?
