Exhibitionism of a sexual nature in which a person takes a photograph of a reflective object, such as a kettle or cutlery, while they are naked so that their naked image appears in the reflection, and then puts this object up for sale, illustrated by the photograph, on an online auction site or alternatively posts the pictures on the Internet.
