I feel a little funny asking this, especially since I've been openly gay for the past 7 years (since age 14), but... how do you know if a guy is gay? I don't mean the obvious, typical gay guy, but just a regular guy you might meet at work or in the supermarket or something. There's this guy at my job that I have a thing for, and he is always really nice to me (he's actually one of my supervisors). I do know that he is single. But how do I know if he's just gay-friendly, or if his kindness toward me should be taken as a signal that he's interested in being more than just a friend? I guess my gaydar is broken, so I need your help!
