why are people who enjoy sex mocked?

nearly everybody on the planet has sex (I said NEARLY)
nearly all of them enjoy it
its completely natural and designed in to NEARLY every living species on the planet....

I know gen Z or whoever is confused about their own sex and fear sex and stuff - but ignoring them, why do people look down their noses at people who get in to sex stuff?

Not really about THIS case because there was some illegal stuff they got caught at, but, if I started a COMPLETELY CONSENSUAL swinging sex group or something NOT doing illegal things, why would anyone care? Heck, groups as that already exist out there, swinging, key parties what have you....

just seems so hypocritical when people run down others sexual stuff. right?
