Sex is dirty. Sex is an expression of love.
Sex has nothing to do with 'Christian' love.
The above statements represent some of the many conflicting views about sexuality with which most of us were raised. You will recognize that the negative statements are the kind that are used by religion and society to control the sexual lives and attitudes of people. In other words, those who have power over others use such ideas to conform others to some moral standard that is thought to be absolute. Traditional Christianity has used just such ideas for just such purposes. Christ and the apostles taught that all power structures were to be challenged, not in the sense of political or social anarchy, but in the abolition of the control of one person over another or any institution over groups of people in the sense of restricting God-given liberties.
