The party was in full swing at 11 pm. Carrying a large bag of leaflets, Kit entered a gay bar in Hong Kong’s Sheung Wan, manoeuvred through the crowd of people drinking and socialising, and handed out free packs, each containing a condom, lubricant and an information card about preventing HIV. “Thank you! These free condoms are quite popular,” a bartender said as they cheerfully welcomed Kit. But Kit, a worker with the NGO Gay Harmony who only offered his first name, was on his last outreach mission.
