Sexual or gender-based violence? This question, far from being a play on words, is at the heart of this book, which attempts to reframe the issue of sexual violence, which is often misunderstood and poorly addressed. Studies often emphasize the sex dimension to the neglect of the masculinity aspect, i.e. the gender dimension. Often the woman is the victim and the man the executioner, whereas the man is both perpetrator and victim. By proposing the expression "gender-based violence", we want to put the man back in his role of victim, he also suffers violence from women, and we want to highlight the other aspects of sexual violence besides the sexual aspect which is often addressed and treated. The reflection opens a horizon by the notion of the culture of peace, which is nothing but the culture of life and non-violence. This book is intended for everyone to reduce the rate of violence related to sex, but more, to students, for scientific research, NGOs and organizations of human rights and protection of women against violence against women will find gray matter.
