Just when I thought I knew everything, says Doug, of California. Fun, tasteful and highly informative, adds Josie from Texas. And who are we to argue with the unassailable testimony of two such reputed sources as Doug and Josie? Nobody, that's who. Besides which, these pocket guides really do offer a bevy of great advice on improving your fellatio/cunnilingus skills, whichever is your bag. And they come with lube and mints. (For making your partner all tingly, not for killing that sushi breath. Though it'd help.)
