Things to consider about gay bars

Hey guys! First time poster here.I am thinking I want to try to go to a gay bar in my city here. I am not out to everyone but I figure I don't have anything to hide from people that are in the gay community. Besides, I probably wouldn't shy away from the subject when asked.Either way, I want to be safe. Don't plan on drinking more than one or two beers.What are things I should know/consider before going? I've never really gone out before. Might take a friend... thinking of going alone?Thank you!
