I don't have any gay friends in London where I live, I've seen there are meetup groups, but I am kind of anxious, has anyone been to any of these in London, what's it like?
Some members of our LGBT group went to London to get good ideas because the ones there are apparently good models for the perfect group (meet up and/or general groups). I haven't been to the group since they came back though, so can't say if the trip was justified. I know this info isn't exactly what you are looking for but I hope it helps nonetheless.
