This book arises from the intersection of two perspectives, in which its authors intend to analyze the dilemma of power between lovers, often unnoticed and unnamed. The stimuli or reasons why two or more people decide to meet and share an erotic experience can be multiple, including some as unedifying as following a custom, fulfilling a mandate or losing control. If the encounters are repeated, the will, the bet, the risk and the ability to choose acquire a more determining role in the erotic relationship. In the midst of desire, enjoyment and fun, chance, instinct and the rush of hormones, what place does power occupy? What kind of power are we willing to imagine and how do we want to use it? In the midst of the presumed rivalries between the sexes, the male-female binarism and the proliferation of identities and “fluid genders”, there are words like autonomy, capacity, right, equality, strength, consent or consensus that have loudly burst in and claim their recognition in the sexual and loving field. Does it mean that we are witnessing the end of seduction? These are some of the issues explored in this work. To do this, Martha Zein and Analía Iglesias have chosen, following the alphabet, 28 evocative words from the universe of love, sex and power, from which to observe the plurality marked by culture and the body and better understand the framework of relationships erotic-sexual in our time.
