Book excerpt: Beyond the basics of polyamory lies a complex web of negotiations, agreements, pitfalls and rewards. Kathy Labriola, a relationships counselor who has worked for many years with singles, couples and groups in polyamorous and open relationships, sets forth some of the realities of alternative lifestyles: dealing with some of the common relationship-disrupters, managing jealousy, choosing compatible partners, combining BDSM with polyamory, distinguishing between sex addiction and polyamory, and much more.
