Hosted on Tristan Taorimo’s openingup.net, the Open List is a list of professionals (doctors, lawyers, mental health workers, and more) “who are experienced and knowledgeable about alternative sexuality and lifestyles, open relationships, polyamory, nonmonogamy, swinging, etc.”
The list is largely made up of professionals in the United States (over 30 states are covered). However a few professionals from other parts of the Anglosphere are included. Inclusion in the list is by request.
