My analysis upon this scenario:
If you are a fan and a persistent observer of a scandal, sexual pleasure; a fascinated observer of distressing, sordid or scandalous events, You are having Voyeurism.
And if you have a psychological disorder causing a compulsion to show the genitals in public and/or showing sexual activities in the public, you are an Exhibitionist.
So you, who watch the Exhibitionist's video is a voyeur! hahaha!
