The separation of sexuality between the one and the other face is according to the understandable wish of humans to draw a line between the controllable and the uncontrollable sexual expression, between the accepted and the unaccepted side of sexuality, between an presentable and beautiful face on the one side and an better to hide or even to fight grotesque face of sexuality on the other side. This workshop puts on a non-voyeuristic spotlight on the "dark side" without being moral.
