To me, coming out requires a concious choice to stop hiding a fact about yourself and make it known to someone. If you aren't hiding it but people can't tell, that's not really different than if you don't wear a wedding ring and people can't tell if you're married or not at first glance. You aren't hiding it so much as just not showing it off.

Hmm that's a good point. In that case, I'm deep in the closet when it comes to my family members(minus my brothers). They're extremely religious and I almost got my ass kicked by my old man for "looking gay" and almost booted out of the house. I'm grown now and my old man is in his 70s, and my mother about a decade or so younger than him, so not really worried as much, but not interested in arguing over an immutable fact about myself. I don't want to give them something to gossip about to the rest of our family, my mother's the worse when it comes to that.

Also, in the closet around in-laws since they're fairly religious too and don't want to cause tension. I'm not religious at all, am secular. So being bi and secular is not a good mix...

The only person I really care about to know is my partner---though otherwise, I normally don't hide it if people ask [ex. "Do you have a girlfriend? Do you prefer women? Are you a ma'am or sir?"]. I just say I like both and leave it at that(and of they ask my "gender" LOL I laugh and say I'm a woman to where they freak out and apologize after thinking I was a "boy'). If they ask for a specific label, I say bi.
