ABSTRACT
Definitional ambiguities regarding violence and aggression in pornography have historically plagued both public and academic discussions the field and have been a source of ongoing contention. Violence has often been defined simply as behaviors directed from one person to another that are intended to cause harm. All the videos in the same-sex samples also had a clear initiator, and most of them also mirrored a dominant/submissive dichotomy, similar to the one found in the heterosexual videos. Certain acts were not relevant for clips featuring two men, and while penetration for m/f videos always referred to a flesh penis, in f/f clips, penetration referred to a sex toy and/or digits and could have been initiated by either one of the performers.
