Four more laps around the track with the pseudonymous sex therapist "Dr. Neil Down" and his trusty assistant "Phil Mycock." The problems faced by this itinerant duo are many and varied (a woman with a phobia about giving oral sex, a woman who wants to tryst with a rock star, and a woman whose panties [N.B.: Not "knickers"] are too tight) but the doctor's prescriptions are remarkably similar: a right shagging. This edition also has a girl who wanted to do a porn vid, and did, and now fancies a return trip.

The usual unhurried pacing, the usual smartarse banter, the usual real-looking birds, the usual quality that we've come to expect from this line.
