i'm going to assume that its the same reason that Jesus is showed bruised, bloody, and maimed dying on the cross, but he still has a loincloth.
for hundreds of years, we'd also hang people in public streets to make an example.
my point: the human race is much more comfortable seeing heavy violence than forced sex. i can't say why, or even if its right, but whatever.
In your expamples its the idea of justice. In many violent movies you either feel the pain of the murder or want him to get justice or both. In many video games you are playing as a soldier, cop, or someone else seeking justice. Even in GTA you are seeking justice against the really bad gangsters and bad cops.Forced sex has no element of justice unless its raping a rapist and torturing them and then killing them.
