Welcome to OpeningUp.net. I created this site as a resource for folks interested in all kinds of open relationships, including: nonmonogamy, partnered nonmonogamy, polyamory, solo polyamory, polyfidelity, swinging, open marriage, mixed orientation marriage, and mono/poly combinations. Check out the Resources section to see an up-to-date version of the Resource Guide in the book. The Open List is a list of professionals (therapists, psychologists, doctors, coaches, etc.) who are knowledgable and experienced with nonmonogamy. Check them out!
