A quote about rape

This quote is from an editorial about rape from the Washington Post. The quote is not the author's words, rather they are a quote from a previous court case, describing the common law of Maryland's stance on rape.

"views the initial 'de-flowering' of a woman as the real harm or insult . . . after this initial infringement upon [her husband or father's] interest in a woman's sexual and reproductive functions, any further injury was considered to be less consequential. The damage was done."

If a woman says she'll have sex and changes her mind after the initial penetration and the man doesn't stop it's not rape because only the initial penetration can be called rape. And that's because the damage to her husband or father is already done. Her value has been destroyed and it doesn't matter what happens to her after that.

What century is this again?
