This completely updated edition with new illustrations adds new tips and anecdotes that could only be told by two women with over fifteen years of experience working at America's leading sex toy store. The book offers explicit, expert advice on sexual anatomy, oral sex, anal sex, S/M, masturbation, and sex and aging, and up-to-the-minute tips on exploring sex online, the buzz on the latest sex toys, and a guide to the best adult books, videos, and DVDs on the market. This third edition of the classic sex manual coincides with the 25th anniversary of the Good Vibrations stores.
