The only reason why I like to go to a 'gay bar' is because I can be myself - you don't have to worry about some 'guy' making some comment about gays/lesbians. Sometimes its more of a safety issue. I'm out, I don't think I need to announce my sexuality, 98% of the people I work with(15 years with this employer), know that I'm gay. I don't flaunt it, don't hide it either, if someone asked I would be honest. Whether I'm gay or straight has nothing to do with my job. Bottom line, just treat your friend as you did before she came out.
