The author apparently didn't learn anything as a pastor. There are reasons for why christian doctrine recommends to practice sex within marriage. One of them is to differentiate us from the rest of the animals by not following our biological impulses only but instead use our brain and self dominance to think what is best in a given situation. Moreover, the difference between having sex with a person you truly love and know and a stranger you met 30 minutes ago is abismal. That tells you open casual sex, whenever however, is not a mentally and spiritual healthy thing for a human being and it eventually takes its toll. Apparently, the author attacks so much the church because she became a religious person focused on that human organization, which probably let her down many times. Instead, she should have seeked a relationship with God and only God.
