The real answer is psychological control of men. The powers that be want to make you comfortable with gruesome, horrific violence, so that your restraints toward police brutality or military killings are lower. And if you really get comfortable, you might even take part in the violence yourself.
Sex? Well, people want to feel good about being prudes against SOMETHING.
I prefer the both or neither approach in media. Give me tits and blood, or keep it PG.
