Marriage and monogamy are not what they used to be, and today many couples are opting to start families before getting married, or deciding not to get married at all. At the same time, gay couples in states that recognize same-sex marriage are getting married in droves. Some people prefer non-monogamy and have relationships that include swinging and polyamory. The landscape of American marriage and relationships is changing, and a variety of family systems are developing and becoming more common. The Polyamorists Next Door introduces polyamorous families, in which people are free to pursue emotional, romantic, and sexual relationships with multiple people at the same time, openly and with support from their partners, sometimes forming multi-partner relationships, or other arrangements that allow for emotional and sexual freedom within the family system. In colorful and moving details, this book explores how polyamorous relationships come to be, grow and change, manage the ins and outs of daily family life, and cope with the challenges they face both within their families and from society at large. Using polyamorists' own words, Dr. Elisabeth Sheff examines polyamorous households and reveals their advantages, disadvantages, and the daily lives of those living in them. While polyamorous families are increasingly common, fairly little is known about them outside of their own social circles or of the occasional media sensationalism. This book provides information that will be useful for professionals with polyamorous clients, educators who wish to understand or teach about polyamory, and especially people who wish to better understand polyamory themselves or explain it to their potential partners, adult children, or in-laws.
