★As a book that combines academic research and practical examples, it provides valuable knowledge and insights for professionals and general readers, and enhances the understanding of abnormalities in sexual behaviour.

Paraphilias, from the Greek “beyond usual or typical love”, are uncommon types of sexual expression often more commonly described as sexual deviations, sexual perversions or disorders of sexual preference. They are accompanied by intense sexual arousal and may appear bizarre or, at the extreme end of the sexual continuum, socially unacceptable. For some, paraphilic behaviour may be sporadic, for others it may be compulsive or addictive.

Dr Mark Griffiths, a Distinguished Professor of Behavioural Addiction at Nottingham Trent University, has been studying non-substance addiction for over 35 years including addictions to sexual behaviour. He began writing a blog in his spare time that chronicled hundreds of paraphilias and sexual perversions. His blog has received almost ten million visitors and this book features many of his most read articles on this topic.

This is both an important and timely book. Some content is likely to be considered by many as truly shocking and horrendous, other material and case studies simply interesting, baffling or perhaps even amusing. To learn more, you simply must open the book and read … and because it’s an A to Z, you don’t have to start at the beginning.

Since 2014 Dr Sutton has published his BigData discovery that busts the myth that no single person read Patrick Matthew’s (1831) prior publication of the complete theory of evolution by natural selection before Darwin and Wallace (1858–1859) claimed, decades later, to have each discovered the same concept.

His current research interests include looking at applying his market reduction approach to reduce sex crime offending.
