"There's no question that it impacted sales," he said. "I think that when people watch adult movies they don't want to be educated. They want to be entertained."

But the adult film industry is not universally anti-condom. Wicked Pictures, for instance, said it has had a condom-only policy since 2004.

Christian Mann, the general manager of Evil Angel productions who played a roll in devising the sexual health database last year, said condoms are unappealing to customers because they take away from the escapism and fantasy inherent in pornography.

Beyond that, Ireland said condoms can make porn sex painful. Even with added lubricant, she said condoms feel abrasive during her hours on set and can cause tiny cuts in sensitive tissue.

"Performers in a sense are sexual athletes," she said. "You go for a long time."

Adult film actor James Deen said the measure also violates his rights to free speech because he wants to portray a certain fantasy for film, and he should have the right to do that. He said he is considering a move to Las Vegas, a possible new home for the Los Angeles porn community. (Ireland estimated the L.A. County group makes up about 95 percent of the business in the United States.)

"We are literally the only community you will find in the entire world that has a zero percent HIV-transmission rate because we are a business. We take it seriously," he said. "All you're doing is restricting my freedom of first amendment rights."
