I don't usually go out and say that I'm gay/bi/pan/whatever. I'll just drop stuff in conversation. Like if we're talking about getting gifts for Christmas, I'll say, "Hey, did you like your kindle? I'm thinking of getting one for my girlfriend." Stuff like that. People sometimes give me funny looks at first, but I've never had anyone stop conversations. So yeah, I just put it out there, without actually saying, "Well, I'm so-and-so, and I'm gay."
