Bf thinks vagina is disgusting?

My friend’s bf thinks vaginas are disgusting she told me he closes his eyes while giving her oral, says her vag pics are gross because it reminds him of brains, and prefers doggy so he doesn’t see it. Is this normal? She told me he never wants to see vaginas. He said his friends say they don’t actually like vagina pics either they pretend to like it to not make the girl feel bad. Can a man be straight and still think vaginas are disgusting? I personally wouldn’t be with someone like that how about you?
