Love is a special feeling. A bunch of novels have been written about him, a million films have been shot. We are waiting for love, thirst for it, consider life without it inferior. But often by love we mean sex. And what role does sex play in relationships? What needs to be more about a marriage for it to last years - passion or understanding, intimacy or tenderness? This book will perhaps dramatically change the way you think about sex. You will learn why most of us deprive ourselves of real happiness by actively having sex before marriage, and what danger civil marriage hides, how to maintain attraction to a partner for many years and how male sex differs from female.
