(nsfw) Men who don't give oral.. how?

I am bi and I only have experience with men. And a couple of them aren't excited by the idea of giving women oral and they focus on "muh dick". Some avoid it altogether and don't do it ever, some others do it occasionally but expect the woman to give oral every time. Giving oral to a woman is very sexy and I wonder how they don't feel that, are they even attracted to women..?
