O'Toole resides in the latter camp in this impressively researched but often intellectually sketchy -- and considering the material, rarely amused -- examination of porn. He details such ephemera as the pictorial progression from the "beaver" to the "split beaver" to the "action beaver" without even cracking a smile. The author attempts to substitute the saliva-spittled hysteria surrounding porn for a more reasoned, analytical treatment. He covers the gamut of pornography's promiscuous variability, from soft-core skin magazines to cybersex chat rooms. Our intrepid eros-explorer goes behind the scenes of the San Fernando adult video industry to interview producers and sexual superheroes such as Julie Rage ("the longest tongue in hard core") and Matt Ramsey, a "human freak in the spray department." In a refreshingly democratic gesture, O'Toole attempts to demystify the business by putting a human face on an industry previously seen as the domain of perverts, pedophiles and rapists.
