Proposal to Ban Porn Shoots Without Condoms in California

California may become a condom-mandated state when it comes to porn ... and the stakes involve hundreds of millions of dollars, AIDS, syphllis, gonorrhea and other STDs.

The California State Assembly has just passed a bill requiring condoms in all porn shoots. The author, State Assemblyman Isadore Hall, III, tells TMZ ... it's all about workplace safety. He says STDs are out of control in the porn industry.

Hall cites a UCLA study, which shows 11% of female porn stars who have sex with males who don't wear condoms contracted gonorrhea and 15% tested positive for chlamydia. We've checked and can't find any documented HIV cases in the straight adult porn industry in the last decade.

Porn honchos tell us ... they are fleeing California. Vivid Prez Steve Hirsch tells us ... his company currently does not produce movies in L.A. County -- where there's currently a mandatory condom law. He says the current testing procedures are more than adequate.

One porn exec tells us ... the county has lost around $100 million a year. Fact is ... we checked with the agency that issues permits for porn shoots. 480 permits were issued in 2012. After the condom law passed, the number plummeted to 40 in 2013, and so far in 2014 ... only 30.

Assemblyman Hall says the porn companies are full of BS ... he says they can digitally remove condoms from the flicks and says, "There's an app for that."

Hall's bill has gone to the State Senate.
