Director Charlie David's latest look at the off-camera lives of male sex workers arrives on DVD September 9.

I'm a Porn Star follows David's successful I'm a Stripper series.

The documentary follows the lives of four established gay porn stars: Brent Everett, Colby Jansen, Rocco Reed and Johnny Rapid. Transsexual adult film actress Gia Darling also appears in the documentary.

In a trailer the film, Everett says: “Not only coming out to your parents as gay is a big hurdle, but coming out to your parents as 'hey, I'm a porn star' is an even larger hurdle.”

Jansen says adult film stars are stigmatized.

“People just assume I'm a slut,” Jansen says. (The trailer is embedded on this page. Visit our video library for more videos.)

According to the film's producers, there are an estimated 370 million pornographic websites online.

I'm a Porn Star is a portrait of people who work in adult entertainment, a business bigger than the music industry,” the film's description reads. “As the story unfolds, it will deliver insight into the personal lives of guys working in pornography, their loves, their hopes and their dreams. It's time to get closer to the action than ever before.”
