The inherent dynamics of free media work against personal sexual freedom. Many media consumers are highly interested in sex. However, sex is intrinsically private. Reporting anything sexual about a specific person in the media has great potential to shame that person, just as nakedness does.
Banning the media from reporting anything sexual about private citizens and public figures would contribute to a society of personal freedom. It would also make a career in politics more appealing to those who have highly active sex lives.
Sexuality does not have to be banned outright from the media. The media could provide sex education.
What ought to be banned is the “this-man-did-that” pattern, because it leads to a culture of finger-pointing.
No prior censorship is necessary. Hefty fines for those who violate the regulations (writers, editors, and publishers) will do the job.
