Condom law takes effect for Los Angeles porn actors (AP) Porn actors are now required to wear condoms on set in Los Angeles, according to a new law. PICTURES - Derrick Burts: HIV-positive porn actor calls for condom use The law took effect Monday, Mar. 5, after Mayor Antonio Villaraigosa signed an ordinance in January requiring that actors in adult movies in the city must use condoms in order for producers to get a filming permit. The AIDS Healthcare Foundation has also lobbied for the regulation for years, saying it's essential to protect adult film actors from HIV and other sexually transmitted diseases. The group is collecting signatures for a November ballot measure that would require condoms on sets countywide. But industry leaders say the new regulation might just take the porn actors elsewhere, although Los Angeles is currently the nation's porn capital. They estimate that as many as 90 percent of U.S. porn films are made in Los Angeles, most of them in the suburban San Fernando Valley.
