Now we are starting to see a different form of monogamy that is "open to variety of lovers" and shares "feelings", "needs", and "desires".
This sexual practice isn't new, we have been seeing these styles of openness in the 1960 through the 70s with the sexual openness of "swingers".
The ground rules adopted by sexually open couples tend to prohibit behaviors that provoke jealousy or sexual health concerns.
Partners may change the ground rules of their relationships over time. Couples in open marriages may prefer different kinds of extramarital relationships.
The couple may remain together while one partner seeks out sexual gratification as he/she sees fit.The O'Neills conceived open marriage as one in which each partner has room for personal growth and can develop outside friendships.Most chapters in the book dealt with non-controversial approaches to revitalizing marriage in areas of trust, role flexibility, communication, identity, and equality.Still, other couples experience serious problems and claim open marriage contributed to their divorces.Ground rules in relationships allow partners to coordinate their behaviors, so they achieve shared goals with fewer conflicts.
