Im looking for a counselor that works with gay couples?

I would like to find someone me and my boy can go talk to, we are thinking about getting married and I just think before we make that step we should get some things out on the table. we are doing fine but we take two steps forwards and then a couple of steps back. without question we are going to make it but a mediator would be cool just to allow some space for to think about some things that maybe we wouldn't have thought about.Im looking for a counselor that works with gay couples?
I would think any counselor would be prepared to work with a couple whether or now you are in a gay relationship.
