For anyone in the Atlanta area I might recommend telecompanions. Dial Tone I know that includes you. Check Creative Loafing for their add and number. My bf and I have used it to add some fun to our relationship.
This thread got my attention...best way to find bi girls is for the girl to hook up with her friends. I'm serious. You'd be surprised how many girls are either bi or bi-curious. I'm slowly converting all of my straight friends into being bi. Next I'm working on my lez friends.
