Newly single lesbian here and yeah, Meetup is the best thing I've found although admittedly a lot of the "meetups" are in DC or Arlington or just not MoCo. There is a queer MoCo Facebook group. Not super active but a lot of members I think, so if you were to join and suggest something, you might get some traction.

Also, tell me more about yourself and I might be able to suggest specific groups.

Check out Meetup. There are tons of groups. There is not likely to be a specific place in MoCo but you will find activities and like minded people. There are bars in DC but you probably already know about those.

I know there's no gay bar in Montgomery County but is there any restaurant or place that a lot of queer people congregate? Sometimes I just need to get away from the cishet majority and feel comfortable. Obviously there's Pride events in June but that doesn't help me in January, you know?
