Religious traditions help us to find our basic orientations in many aspects of our lives. The most important aspect of our lives is how we interact with others. Among other things, this means religions often have a lot to say about sexual ethics. What sexual ethics does Buddhism promote? In this area our tradition speaks more quietly than others, which can leave newcomers wondering if it addresses the subject at all. In fact it speaks quite firmly. In opening up the subject I'll highlight those questions that bear on the issues raised by various liberation movements - by the women's movement, by gays and lesbians, and by the smaller sexual minorities. I don't think I could be too wide off the mark in saying that all these movements whatever else they are about, are engaging with various forms of prejudice, and with violence and violations based on those prejudices.
