Porn star Mr. Marcus admits that he could be responsible for the recent STD scare that has shut down the porn industry in San Fernando Valley, California and is now apologizing for it.

In a recent interview, the 18-year porn veteran said that he believes he contracted syphilis while on the set of an x-rated video, and he also admitted to covering up his syphilis-positive test results so that he could continue to perform.

Mr. Marcus the Adult Video News (AVN) that on July 11th, he felt sick and went to his personal doctor, who ran tests, and the next day told Mr. Marcus that he had tested positive for syphilis. A day later, he was given a penicillin shot and told to abstain from sex.

“My personal doctor doesn’t know what I do for a living,” Mr. Marcus said. “So his thing was just don’t have any sex for 7-10 days. Once I did that shot I felt pretty confident. Every doctor I talked to up to that point said, ‘You get the shot. That’s it.'”

Mr. Marcus returned to work and shot a sex scene 11 days later, on July 24th, although subsequent testing showed that syphilis was still in his system. He says that the producer of that particular shoot only asked to see “proof” of a test, rather than a full paper/digital copy.

Taking advantage of the situation, Mr. Marcus says he showed the producer a copy of the results on his cell phone, but admits to hiding the part that showed that he tested positive for syphilis.

“I showed that my HIV was clear, my gonorrhea and chlamydia were fine,” he told AVN. “You didn’t see the syphilis part of the test because of the way I showed it.”

For a subsequent porn shoot, Marcus said he folded his test results, covering the syphilis portion, and photocopied it … however, the producer noticed this time that the syphilis portion was missing, and called the porn star out on it.

“I tried to cover it up… Because I said it was like the scarlet letter. It’s the word. Syphilis, whoa,” Marcus told XBiz in another interview. “Mr. Marcus, syphilis? Mr. Marcus, the one I worked with? The one that everybody works with? The one that’s been in this industry forever?”

Mr. Marcus said that he only altered the test because his doctor told him he would not be contagious 10 days after taking the penicillin shot.

“I have to live with this, no one else does,” he said. “I’m very sorry. I did not think that this would come out like this.”

What’s really shocking about all of this, is that even though he admits to having sex with performers while he had an STD, Mr. Marcus honestly doesn’t think he did anything wrong.

“I don’t feel that was a mistake,” he said. “I was treated. I allowed the medicine to take effect, and I wanted to proceed as normal. I wanted to go back to work as usual.”

Mr. Marcus’ admission comes after reports surfaced of a syphilis outbreak among porn performers, which prompted a 10-day stop in production so that over 1,000 actors could be tested.

According to AP, as many as nine syphilis cases have been identified among porn performers, and more are expected.

All of the women Mr. Marcus “performed with” have tested negative for syphilis.
