And at the same time, it will help answer troubling questions about sex that are sometimes embarrassing to ask even the closest people. Puberty - what happens to the body, feelings and thoughts? How long does it last and what happens to the body and psyche? Masturbation – shameful or normal? Is it possible to get pregnant if you have sex without a condom? Stages of relationship development from first love to first kiss and sex. How to build relationships? What does self-esteem have to do with it? Boundaries - how to protect yourself in relationships and from the aggression of others? First sex - what to do, what to do? What if it doesn’t work out? Everyone will find answers to their questions in this book: teenagers who have barely set foot on the path of sexual development, boys and girls taking their first steps in serious relationships and attempts to have sex, as well as married couples when both feel that they need help with marital sex and family building.
