The explanation of POV Porn:

Point of view pornography (POV) is adult entertainment that is filmed as if the watcher had experienced and filmed the happenings. In a POV porn the man receiving sexual gratification holds the camera himself and aims it down at his genitals and the partner(s) who is/are pleasuring him. This is in contrast to having a separate camera crew filming the action. The effect is to give the viewer the sense that he is experiencing the sexual acts he is watching as opposed to simply watching others as a voyeur.
