Toilet paper isn’t the only thing in short supply!

With millions of people cooped up in their homes due to the coronavirus pandemic, porn fans are being denied fresh, American smut due to a “mandatory production hold” imposed by the industry’s leading trade association.

The Free Speech Coalition called a halt to the filming of X-rated action over concerns about the testing that some actors recently underwent for sexually transmitted diseases.

The FSC said tests processed by Talent Health Labs of Los Angeles didn’t meet the protocols mandated by the industry group’s “Performer Availability Screening Service.”

“We do not believe there are any active cases of syphilis or HIV in the talent community, but need to clear all talent who recently tested with THL before we can lift the hold,” according to a message for Saturday and Sunday on the FSC website.

The shutdown order, which was announced on March 17, will likely be lifted when re-testing of “all affected talent” is concluded on Tuesday, the FSC said.

But a “voluntary hold” announced March 6 — following “a report from a performer who believes they have a presumptive case of COVID-19” — will remain in effect.

“For our own safety and the safety of the community, no one should be shooting or creating content with others,” the FSC said at the time.

The coronavirus pandemic has led some porn stars to shift to solo performances, with several “cam girls” actually reporting a boom in their business.

Talent Health Labs — founded by porn star Kiki D’Aire, whose credits include “Silicone Sweeties” and “A Knight of Bondage” — didn’t immediately return a request for comment on Sunday.
