I don't know if you've tried the ok cupid dating site, but it's a great way to meet poly people. Write a great profile, post some nice pix, answer lots of their Q&As and tests, and you'll find some matches, if you're charming and interesting enough.
Worked for me! I've got 3 poly lovers, a woman and 2 guys.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
