I just finished a doctoral course on human sexuality. A few observations.
1. Stick the basics. God designed sex simple. One person for life, one in heart, soul and body. God is the Master Designer. Move away from the Master and the design gets confusing.
2. Sex is about connecting through the spirit using the body. This connection is built upon mutual exposure and seemingly weakness that produces great joy and strength. Sexual union that is wonderfully celebrated echoes God's heart for the family and the order which creation is dependent upon.
3. Sex is Powerful. God designed sex to be an oil to help married couples move through life together. Kept in its place it wonderfully celebrates both the male and female design.
4. Sex is Dangerous and Mysterious. There are certain aspects of the sexual experience we do not fully understand. Science continues to seek to understand the impact of right sex and wrong sex upon the mind, soul and spirit of the human race. The damage that is done to children is mystifying and defies evolutionary conclusions about our being.
God says enjoy, eat as much as you both enjoy, stay out of the ditches, stay on the road and keep looking ahead.
