There is little research on the causes for sexual violence. It is quite a while ago when I published a study that explains the link between sexuality and violence.Schneider, Andreas 2002. "A Possible Link Between Stigmatization of Sexual-Erotic Identities and Sexual Violence".Sexuality & Culture6,4.
Additional information: The Sunny Side of Smut (https://www.scientificamerican.com/article/the-sunny-side-of-smut/ ) summarizes contemporary research on pornography by local colleagues at Texas A&M and Texas Tech University. Two leading participants in the porn industry: Ron Jeremy (https://en.wikipedia.org/wiki/Ron_Jeremy ) is one of the most successful male porn actors and later porn movie director. Ron provided a very revealing discussion of the porn industry at the Student Union Allen Theatre at Texas Tech University. Beate Use (https://en.wikipedia.org/wiki/Beate_Uhse-Rotermund ) revolutionized the European sex industry. There was a focus on providing "clean" nonviolent positive sex content to a wide audience.
