How do I come out as gray-a and it explain it to others?

Gray-a is tricky. My wife is gray-a and she hasn't bothered to tell anyone because we were already married when she realized, so she just kind of figured there was no point in her coming out to anyone but me. If I were in your shoes, I'd probably take it one step at a time and ask myself a few questions: Who do I want to tell about this? Do I want to tell them one-on-one or in a group? Is there a way I can make myself more comfortable when coming out to minimize nerves? Do I want to give the people I'm coming out to an opportunity to ask questions? Are there only some people I want to give the opportunity to ask questions? Do I want to come out all at once or gradually? I know that's kind of vague, but I hope it helps.

You can start by talking with the people you trust the most and those you know to be supportive of LGBT realities, so you'll feel comfortable, and you'll also feel stronger when you'll start feeling support! Maybe you can tell them first how you feel and how you came to realize who you are, and then introduce the label to them. Many people have never heard of it, so maybe you can explain the concept first and introduce the word later, so they'll feel less confused. Make sure they know you're there to answer any question they might have, and that you wanted to share this with them because they're important to you and you want them to know the real you.
