husband won't give me oral

So this group is supposed to be for men but I thought maybe the guys here could help me with a problem. My husband refuses to give me oral. I give him blowjobs and love it but he says he's not into giving oral sex because it doesn't "taste good". He's never even tried with me. I keep myself clean and I am infection and std free and he is the only man I've been with. It just doesn't seem fair to me. I read about guys who love to give it to their wives and gfs but mine won't even try yet complains when I won't swallow. How can I convince him to try?
