Not enough!
But seriously, I feel there is still way more gratuitous violence than gratuitous sex on film and TV. I can't say how many times I see some movie where the protagonist with a gun shoots his way through 20-30 "bad guys with guns". It's super unrealistic and I think it causes much more social harm than gratuitous sex because, at least in the US, it reinforces the stupid "good guy with a gun" myth. Super hero movies are sort of the same, reinforcing the idea that only through violence can problems be solved because of "bad guys". I think we could probably use some more sex-centric shows like The Deuce or Masters of Sex and less stuff about people using guns (or super powers - a gun metaphor) to solve problems.
