Sex is a marvellous part of life, but like all parts of life it can go wrong, and nudge-wink secrecy plays the devil with it. People need information, respect, and encouragement to discuss it openly. Some misled men developed the incredible idea that sex was wrong, and sexual attraction was a bad thing to be blamed on women, but the idea of a celibate clergy did not come from Jesus, Mohammed or the great Jewish and Hindu sages. Celibacy was imposed on priests in 1074 by Pope Gregory, causing havoc that lasted for centuries, and has little to teach teenagers who know that sex is good. All religions know that people are physically capable of making love long before they are socially or emotionally capable of making families, and advocate virginity as a highly attractive and satisfying aspect of early development.
Sex is a most complicated part of being human.
The sperm must be blasted into the egg and the future can look after itself. Like food and drink, sex demands self-gratification, but sex dresses its passion in romantic dreams and the music of emotion. The whole process is linked to powerful feelings that lift people to a new level of experience capable of making poetry, music and philosophy, which are out of this world. I love you and you love me and therefore we do this wonderful thing together. A major factor in today's culture is the attempt to remove the romantic emotional aspect altogether, and accept sex between humans on the same basis as between dogs and cats, with no love or emotional commitment.
