Boy George once famously opined that he'd rather drink a nice cup of tea than have it; James Dean likened it to an ice cream sundae, and the late Hugh Hefner called it the driving force on the planet. Yes, we're talking about sex!
These days, it seems hard to get away from it. Books are full of it, films are devoted to it and sex seems to be the key ingredient for any self-respecting music video.
But it wasn't always like this. Up until a few decades ago, sex on screen was very much a hidden affair. Television networks would cut out offending scenes and the barest hint of flesh relegated TV shows to late-night time slots and feature films to R18 theatres.
But despite the restrictions imposed on writers and filmmakers, they persisted, and the subject of sex became a staple of both the small and large screen.
In New Zealand, one of the first documentaries to look in-depth at our sexuality was Allison Webber's 1987 series Expressions of Sexuality. It took her two years to convince TVNZ that local audiences were ready to talk about what was still, in those days, a taboo subject.
