Coming Out Day

So I barely noticed National Coming Out Day: Like every year, it passed pretty much without any actual coming out.
And then like three people on my news feed were all, "Hey, I forgot it was National Coming Out Day yesterday. Newsflash: I'm_________." Some I already knew, some were not a surprise, but I'm having feelings about it because I've never done it.
At some point, I built it into my lexicon for dealing with new people. I don't hide it. It comes up in conversation. It does this a lot of ways.
"My girlfriend--"
"Why did you_____?" "Well, I'm a lesbian, so---"
"Wait, are you--?" "Gay? Yes."
So everyone at college knows. My parents know. My close friends know. My grandparents on one side at least know.
But not most of my extended family, and not most of the people I knew through middle and high school--who make up the majority of my facebook friends. At least, I don't think they know. People have surprised me before.
"Congratulations on coming out!" "Thank you. How did you know?" "You know, the Internet."
Part of me feels like I should. Visibility is important. Visibility is a thing I advocate. And I feel like I'm talking the talk but not walking the walk to stay closeted.
And it's no longer a thing that would likely get me outright disowned or a large amount of nasty messages sent my way. I expect a couple "It's a sin, repent" messages, one or two, maybe, and my relatives talking around it for the next forever, but I can live with that.
So why am I still not doing it? Why am I still scared?
Partly, why should I tear down my shields and allow in the messages and the judgment when it's not negatively affecting my life not to be out to some people? The people that needed to know, the people it was hurting me to stay in the closet for, they know. Why should I expose myself that much more? Is it that likely that there's someone on my news feed that doesn't already have sufficient gay role models?
Sigh. I knew it wasn't my duty to come out as long as it would hurt me. Not sure what the right answer is now.
Atalanta says stop using 'should' statements. I'm not sure I know how to police myself without 'should' statements.
Hello, everyone. I'm a Kinsey 5, that's predominantly homosexual/romantic and only incidentally heterosexual/romantic. I'm sexually and romantically attracted to women almost exclusively, to their minds and their souls, not to their bodies. I usually identify as female but once in a blue moon experience brief dysphoria. I touch on the asexual spectrum extremely lightly, so that I almost always have to have heard someone talk, enough to get an idea of their personality, to be attracted to them, but mostly identify as allosexual (not asexual). My gender expression tends toward fellagirly with a large helping of genderfuck, which means I sit like a guy, grow my hair long and dye it, don't wear makeup or shave my legs, appreciate jeans and skirts, love suits, vests, and ties, and occasionally do makeup/police my body language/bind/dress/wear a wig specifically to make people question my pronouns.
