yes, exactly. They ennobled the adulterous affair, and made it the quest for young men to steal the affections of an older married lady. The woman did not even have the right to reject the lover's attention, and a married man had no excuse not to seek the favor of other women. All in the name of love.
I don't know if people back in the 12th century really bought these stories, but I know people today do. And keeping it non-physical seems to be lost in the past. Today's object of affection doesn't mind getting down and dirty.
