Volkmar Sigusch, the founder and dean of German sexual medicine, is consulted almost daily: by German-speaking and international media, for whom he is one of the most "interpretively powerful" contemporaries and a sought-after conversation partner, by colleagues from around the world, by patients, students, and doctoral candidates. In the form of a lexicon, this unconventional "Sex ABC" compiles Sigusch's answers to frequently asked as well as obscure questions about sexuality, pleasure, and desire. It provides an entertaining overview of knowledge about sex and surprising insights into the current world of new sexualities. A vademecum for discerning contemporaries - suitable for pocket or bedside table. "Sigusch is considered one of the most important sexual researchers internationally." Der Spiegel.
