Open Marriages

It's estimated as few as 1% of people are involved in "open marriages". It is an umbrella term that covers a lot of different practices, but most simply put--couples are allowed to have sex outside of their committed relationship.

In a world where half of the US marriages end in divorce and affairs are common, often breaking up families, open marriages get a lot of heat.
