I had very difficult time finding potential providers for couples. Many are double+ the price for couples, so TER's price was way off. The only indication that the provider is into couples is if the profile says bi. When I called these "bi" girls they said they weren't or they weren't into couples. And I found some that were not listed as bi in the profile and yet advertised that they were into couples on their web site. Moreover, TER should have the provider's schedule. Why not? Most providers supply that info if they work on weekend or their hours. For a couple the provider's schedule is much more key as the schedule has to work out for 3 people. I ended up eliminating most potential providers due to scheduling conflicts.

I agree that more couples friendly info would be great.  I think the bigger problem is finding a wife that is open to the idea of another lady
