Most STDs are treatable or some you can get a vaccine against like HPV vaccines at Costco for $20.
Those that aren't curable like herpes are still passable as most porn stars have it. They just don't have sex during an outbreak. Herpes is not tested against when doing STD tests for porn because it would eliminate most porn actors from filming.

HIV used to be a death sentence but is now treatable too.
They're actually milder than many airborn diseases like Covid. STDs are illnesses like any other. They are just used to stigmatize people.
That being said I get tested and I don't have STDs. It's just funny to me that you try to stigmatize people using treatable illnesses.
