Shashank_Rosberg saidParents are sorta heart patients.... Have a sister in New York, very few good friends.
Who should i come out to first and how/what should i tell them? 
Any Suggestions?
Reality is that, unless you're having sex with them, someone doesn't need to know. That being said, ask yourself the pros and cons of making a proclamation / big deal with the folks. If you think the pros outweigh the cons, then, proceed, otherwise, leave it alone. Almost certainly, unless they're complete idiots, they know already, and don't care. You likely need to give your relatives a bit more credence than you do now. If you're gay...as I say.....then almost certainly know unless they're the ignorant sort, and, reality is, do they NEED to know? Do you plan on fucking them?
In a world of 7 billion folks, to get wrapped up in one's own sexuality is a bit silly. It is whatever it is, and, the only folks that really need to know (and they will) are the folks that you're having sex with. Other folks can think what they want, etc.
I don't hide my sexuality. In fact, I'm very open about it, but, there's little to be gained by adding drama to your life. If telling the folks is a drama thing that adds no value, then...it's logical to not do it. If it's important to you that they KNOW your sexual preference, for certain, then, tell them. It's just sexual preference, and no big deal.
Homo, hetero, bi, and asexual all happen all around us in Nature...all the time. In the big picture, your sexuality isn't much of a thing.
It's very easy, and lots of folks do it, to get COMPLETELY caught in the whole sexual preference / self-identification / gay role thing. That's just plain STUPID.
Tell 'em if you wanna'; don't tell 'em if you don't wanna / it's a big drama. Get on with your life. You dig boys. So what?
Go tell everyone, if you want. You'll learn fast that your sexuality just simply is not that important to the vast majority of folks in The World. No one fucking cares unless they're nuts, and...why would you want anything to do with NUTS?
