Your bodies are members of Christ. What you do with your body always touches your spirit. Sex, therefore, is never just a physical thing as some would have us believe. No, it was just a physical thing. Sex never has been and never will be just a physical thing, like playing tennis or dancing.
Sex is an intermingling, or a blending of two entire personalities - body, soul, and spirit.
Don t try to tell a medical student you can damage your body through sexual involvement. It s a function that God created your body for, for goodness sake. We damage our being in every sexual act committed outside of God s limits because we become one with someone else. Blended and intermingled. And then in a few minutes we tear that oneness apart into two beings again.
