In a film of startling power and unsettling intimacy - produced exclusively for wallpaper.com - video artist and photographer Robbie Cooper shoots back at active porn aficionados lost in ecstatic release and hears how their passion developed. Be aware that this is not easy titillation and some of you may find the footage shocking. But the film does throw up any number of questions about voyeurism and exhibitionism and makes clear the incredible nakedness of the solo sex act.

This film is part of Cooper's on-going Immersion series, for which he captures people's reactions to different media via a camera attached to their screen. The artist has now launched a Kickstarter campaign to help him take the series global. Read more about the project.
