More about the subject of how prevalent it is for male addicts of various sexualities to engage in gay prostitution-

Providence, RI- A man sits in the sunlight on a concrete barrier along Allens Avenue, where strip clubs and adult bookstores line the industrial road near the Port of Providence. He's speaking in a film about his life, and the lives of other men like him, who prostitute themselves on the streets of Providence to survive — and support their drug addiction.

"There's a lot of people like me, more than you'd ever think."

"Invisible" a Grauman Films documentary, goes into this underworld to hear from the men about how they ended up on the streets of Providence and what their lives are like. The guide is Richard Holcomb. He says he was 14 when he began jumping into cars and robbing men who solicited him for sex. By 20, he was a drug addict, homeless, and selling sexual favors to men to survive.

After being diagnosed with HIV in 2007, Holcomb went into rehabilitation, and his experiences made him an advocate for other men who were also trying to leave that life behind.

He and James Waterman, another recovering drug addict and former sex worker, started going into the streets and adult shops in Providence with backpacks that held clean needles and condoms. They founded Project Weber, named for Roy Weber, 22, who was working as a prostitute and murdered along Allens Avenue in 2003.

To help state health officials understand, Holcomb received a $5,000 grant to survey 50 men working as prostitutes and ask questions about their lives.

"I went back to the areas where I used to sell myself, and I'd see kids there who were just like me," he said.

Their lives are defined by a combination of drugs, homelessness, mental illness and abuse. While some men have wives or girlfriends, they turn tricks with men to support their drug addiction. They work in alleys, adult bookstores, parking lots along Allens Avenue and through dating apps, where they advertise "PNP" — the initials for "party and play," meaning drugs and sex.

They risk HIV with shared needles and sex without condoms. They risk death from overdoses and violence.
