If one subscribes to the theory that beauty is in the eye of the beholder, it's inescapable that eroticism is no less so. Few videos so clearly drive home this concept as Charles Gatewood's documentaries on erotic tattooing and body piercing.

In Part 5, Gatewood interviews nearly a dozen of these "Neo Tribalists" and, like the multicolored pictures they wear on their skins, each has a story to tell. Included are displays of pierced labias, clitoral-hoods, penises, nipples, and — not for the squeamish — a couple of actual nipple-piercings are shown.

How erotic you find Gatewood's video depends on you, but for those who know little about this "counter culture", like any good documentary, Erotic Tattooing & Body Piercing Vol. 5 is undeniably educational, and that's always entertaining.
