Never had a orgasm

I posted this in another group as well but me and my husband has been having sex for about 6 years but I’ve never been able to orgasm. Don’t get me wrong sex feels really good and I’ve gotten really close a few times but then it just goes away. I don’t know what to do. He’s good at what he does and he try’s so hard but I think maybe I just focus on trying to make myself have one so much that it prevents it from happening. Does anyone have any tips??
