GOD I am old and I am really old fashioned. Why get married? Just float your bed strolls while single. For me, marriage is between two people who doesn't want or need or tolerate anyone else, but each other in their bedroom or relationship. Many who have tried open marriages and relationships have failed and usually causes  more sorrow and jealousy problems than contentment and happiness. For all the partners. Divorce courts and Cemetaries can attest to that. Trust and fidelity is a major demand for me.
