At the beginning of the last century, Sigmund Freud suggested that a person's character is associated with sensitive holes on the body (mouth, nose, ear, eye, anus, urethra, skin, navel). He did not yet know or, perhaps, was not ready to openly declare that the sensitivity of these holes determines all areas of a person's life: from health conditions to sexual addictions, from the choice of profession to the style of doing business. In this book you will learn what types of people exist depending on the leading erogenous zone and how to apply this knowledge in different situations of your life.
