Jennifer S. Dobrowitz is a GP doctor. She wrote an eBook "Learn to lick - Cunnilingus: From Mastery to Art and Beyond" that will teach you what you've never learned before about oral sex. The book is in plain English, with clear instructions on how to give the most incredible lick ever. The doctor wrote it not as a medical scientific paper but more like a friend - to - friend advice collection. This eBook is great value for money as it offers not only oral sex techniques and positions, but also information about STDs, protection to be used in oral sex, ideas on how to create great atmosphere for intimacy and many more.
