Congratulations! I admire your strength and respect you for your honesty.
A tiny little bit of unsolicited advice: Just remember that you'll be coming out for the rest of your life. Think about how you want to frame it, because others will take their cue from you.
For example, if you sort of hang your head, or drop the volume of your voice when you say the word "gay," or in any other way act as though you're ashamed of being gay, others will pick up on that, and they'll treat you either as a victim (and act condescendingly toward you) or as a taboo person (the "white wolf" that the others turn on and either kill or drive out of the pack).
But if you act assertively and meet people's eyes as you say the words "I'm gay" and smile and act comfortable in your own skin, people will follow that cue as well. Even the homophobic ones will say some of what I said above, including "I respect you for your honesty."
My best to you, and PM me if you'd like to hear some examples of my continued coming-out scenarios in this heterosexual-assuming society.
