Ancient philosophers argued that “love and hunger rule the world!” If there is no food, there is a threat to human biological existence. And if there is no love, then life in its content is limited to this biological existence. It is no coincidence that all world literature, drama, and cinema are based on the cult of sexual love. Love is the quintessence of human relationships. From a purely medical point of view, happy sexual love maintains mental and physical health, improves relationships with other people, increases self-esteem, and creates a feeling of completeness and meaning in life. But how can you ensure happiness in love? Or at least establish a fulfilling sex life? Each person independently seeks answers to these questions. This anthology, dedicated to the ancient but always relevant “science of love,” will help him in such searches.
