The ‘create their own stories’ thing was a ploy. They were either using it as cover to try and conceal their racism or they were betting that people of color wouldn’t be able to make their own works and find an audience. They don’t actually want new black characters; they don’t want black characters at all.
In my experience (which is limited, I don’t often ask friends about their mastubatory habits) most men have about a1:1 porn to masturbation ratio as well.
As in without any physical stimulation? I’m pretty sure that’s not very common, but I may be wrong.
