Human sexuality touches all of us, pun intended. We all either enjoy it, struggle with it, or may have been its victims. Humanity has dealt with this central issue for decades, and we still continue to learn as science and research are progressing and developing. When discussing sexuality, we mean human sexual functioning, the physiology of sex, the hormones involved and how they affect us, and the cultural norms related to it. However, when sex is not functional it is a problem that can affect us in significant ways. This book will describe and explore its causes and the reasons that those dysfunctions are maintained, and what treatment methods have been proven successful. Amongst its other contributions, this book will place sexuality where it belongs: within the context of relationships, and will demonstrate how it is related to intimacy and may enhance it, how it may be negatively influenced by destructive relationships, and how dysfunctions or paraphilias may influence the intimate union. This book covers issues, angles, and points of view which are not commonly covered in sex books for the general public, replete with recent and updated information.
