It should be, but the law has not acknowledged that for a long time. And in some areas, it doesn't to this day. South Carolina, for instance. Even today, their laws require 'excessive force' to prosecute marital rape. Not enough if the wife says she did not consent. She must demonstrate that the force or violence used against her was grossly extreme. It is ridiculous and evidence of this doctrinal interpretation of wives owing their husband's sex. Consent should be given for every single instance. Marriage would not take this basic right away, yet it still does in so many places and cultures. People believed a wife should obey and cater to the husband's needs. And it isn't even in conservative cultures. Even here in the so-called modern world, this idea stays. Women who say no to sex are branded not to be 'good wives,' and this is justified through religion and popular culture. Ah, that shows how much control is involved. Marital rape, as you said, has got nothing to do with closeness or love-it has got everything to do with control and power. It's one person's feeling that they can take whatever they want from their partner regardless of the other person is feelings about it.
