Brian, a 40-year-old project manager from Sydney, Australia, starts his mornings by jacking off. Before he gets out of bed, he grabs his phone and scrolls through sites like OnlyFans and XVideos, blowing his load after 10 to 20 minutes of porn-fueled jerking. Then, he gets on with working from home—until about lunchtime, when he'll usually treat himself to another midday porn blitz, especially if he's feeling "bored or low."

Brian calls these viewing sessions "fixes," and describes himself as "definitely addicted" to porn. He admits his habit was more extreme in his 20s, when he'd binge porn for "hours on end," but today he still struggles with sticking to self-imposed periods of abstention. "I started a daily one-hour mindful meditation practice and did weeks of retreats [to kick the habit], but I still keep lapsing back into porn brain," he said. "I try to go clean, but something always draws me back in."
