Beyond frustrated..

Going on 5 years of marriage coming up in October, and lately all my husband wants is oral sex, if I offer something else he gets mad and just says he will just stop asking for everything and that I just obviously don't care.. I'm beyond frustrated because I do care, but I also don't want to give a blow job every day with nothing in return. If I ask what he wants to make it better so its not so long he just says obviously you don't listen . which I do but he literally never gives me an answer on what he likes. I have tried buying different things to see if that helps, but it's literally the same argument... I'm at such a loss. It was never like this till the last year, we use to have sex often.
