Places to meet polyamorous black gay men in Washington DC/Baltimore?

I'm in a one year open relationship relationship. It is a first for the both of us. We are open but wanting to explore the possibility of a poly relationship, especially since our sexual compatibility doesn't match up but also because we believe people can have multiple "true loves" so to speak. IDK. Just wondering if anyone has any info on somewhere we could go to meet black "poly" gay men in the Baltimore, Washington DC area?
