I think is huge lie and injustice to punish a guy for marital rape.
I mean the concept of rape and it it's legal definition was made to protect foids to protect her reproductive ability. So that she can trade it with man for his resources , this is the unwritten idea of marriage.
Ok we can say that to an extent a husband should nt force his wife. But the wife can deny him sex forever. It's her obligation to fulfil his needs regardless of 'her mood'. In my opinion If she get traumatized by when her husband has sex with her then there is something wrong with her mental makeup and it should be dealt by a sexologist . Rather than getting the state to involve in the matter and punishing the husband.
As I said before 'rape' is just legal term we can't apply it to every situation. For eg 'murder' is a crime. But we don't punish soliders for murdering terrorist. The act is the same but the Context differs.
