One thing I see constantly in this thread is the idea that Martin is depicting the ancient or medieval world and rapine was a common thing in warfare then. That may be so but we should remain aware that more women were possibly raped on the Eastern Front in WWII than in the entire medieval period. Rape is an aspect of power, not sexuality, the only sexual thing about it is that its uses the sexual act. Rape is a weapon of terror and it has been used as such in war since the beginning of history and continues unabated to this day, as anyone familiar with present conflicts in Africa is more aware of than most. Martin would be extremely remiss in his efforts to portray his world "realistically" if he did not acknowledge this, as Tolkien and many other writers have failed to do (That is not a criticism of Tolkien, who was not trying for realism, but Martin is.)
