But from the beginning of creation, God made them male and female.
For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. Therefore what God has joined together, let no one separate.
The meaning of "open marriage" can vary from study to study depending on how the particular researchers have set their selection criteria.
There are variant forms of open marriage (such as swinging and polyamory), each with the partners having varying levels of input on their spouse's activities.Fueled by frequent appearances of the O'Neills on television and in magazine articles, the redefinition entered popular consciousness, and "open marriage" became a synonym for sexually non-monogamous marriage.In her 1977 book The Marriage Premise, Nena O'Neill advocated sexual fidelity in a chapter of that name.Most of the book describes approaches to revitalizing marriage in areas of trust, role flexibility, communication, identity, and equality.Chapter 16, entitled "Love Without Jealousy", devoted 20 pages to the proposition that an "open marriage" might possibly include some forms of sexuality with other partners.
