A non-judgemental presentation on BDSM (sadomasochism) that analyzes this specialized taste without hyperbole or alarmist language. The author's aim is to de-demonize it in its consensual form and to offer aid and guidance for those who harbour such interests.
At least that's what it says on the back cover.
I really should tip people off that there is a newer edition. If you are looking for general advice or ideas for play, this will work fine. Not much has changed. However, if you are looking for a partner, the newer edition has a completely redone and updated chapter on that topic.
