Sexuality is freedom-and vulnerability at the same time. It can connect, heal, and bring happiness-or endanger, destroy, and silence. But why do people take risks even though they know the consequences? Why does sexuality so often become dangerous in situations where it actually promises closeness? This book explores these questions-without moral judgments, without fear, but with scientific depth and human clarity. It combines insights from medicine, psychology, sociology, and ethics to create a comprehensive picture of sexuality in the 21st century. From unprotected sex to emotional dependence, digital intimacy, and pornography consumption to social and cultural influences, the author shows how risky sexual behavior arises - and how it can be avoided without losing pleasure, diversity, or self-determination. The focus is on the idea of a new sexual culture based on knowledge, respect, and mindfulness. A culture that does not treat sexuality as a danger, but as an expression of responsibility and humanity.
