This marvelous out-and-proud documentary is part of Channel 4‘s season celebrating the 40th anniversary of the decriminalisation of homosexuality… and what a celebration it’s turning out to be. Looking mainly at the blokes of the scene, How Gay Sex Changed the World showed how once, gay men would be physically bullied by police, and now, are free to do as they please. Sometimes, that means being gloriously camp, more importantly, it means gay men are free to have a kiss and a cuddle in public.
