Thanks for this wonderful thread.
I honestly believe that these identifiers are very important, even for someone that doesn't interact with them on an everyday basis.
I am
biromantic. I experience romantic attraction both to my own gender and any outside of it.
I am
demisexual. I am somewhere between asexual and sexual. My default state is asexual, but I can become sexually attracted to someone if I form an emotional(not necessarily romantic) connection to them.
I am a
demiwoman. Sometimes referred to as a demigirl or demifemale. I identify with aspects of the gender binary and womanhood, but I consider some aspects of my gender to be nonbinary.
...but those identifiers inform my internal viewpoint more than how others interact with me.
Strangers/acquaintances/co-workers just know and interact with the
woman part of that identity(and under the assumption that I'm cisgendered and straight). Friends might know me as a
gay trans woman. My closest friends may know and recognize the intricacies of my identity, but it's mostly something that
I use to identify me, recognizing that others will not and do not need to recognize my gender and sexual identity with such nuance.
That said, some people are going to wear the intricacies of their identity on their sleeve, and that's okay too. If someone thinks that this is overdoing it or in some way inappropriate or embarrassing, remember that straight, cis people do this
all the time. If you don't have a problem with it then, you might want to take a look at why.
I've also heard of another definition of bisexuality where the 'bi' doesn't mean two genders, but rather means the dual collection of people that are your gender as well as people that aren't your gender. I identify as bi and prefer to think of it in those terms.
This is what I mean when I refer to myself as bi, as well.
