Honestly, from my experience in a very backwards US state.
A) Keep it on the down low, if they aren't:
--A Trustworthy Friend u want to talk to about it, (e.g. fawning over a nice piece of booty)
--A Family member you want to introduce your long term S.O.,
--or someone who only knows you anonomosly, so little chance of a backfire.
Well then do they really need to know?
B) If you're in a homosexual relationship, just let people assume you're gay, unless you're looking for a poly relationship, it isn't worth the effort to correct them, and sometimes you come across as having a stick up the pooper.
The same goes for straight relationships, NBN (non-binary) ones are harder, personally I try to match whatever they are presenting as, but that doesn't always work down here.
C) Trustworthy friends are amazing, remember though the LGBT+ community has just as many bigots as the rest of the population, and bisexuals are a popular target. Keep a stiff upper lip, and imo avoid the toxic people, they aren't worth your time.
But seriously, having someone to confide your feelings in, and ask for a second opinion is amazing, infatuation can make you do dumb stuff sometimes.
That feeling. I've recently developed an attraction to someone of the same gender, and having been asexual for as long as I can remember, feel pretty unsure about telling people. It's not that I fear bigotry, it's that I feel like I'll suddenly be classified under a label, even though I don't feel gay, or bi. I feel like me.
I am and was in a similar situation. As it turns out I'm Demi-sexual (Asexual with exceptions for people I have a strong connection to). Labels are only tools though, so many people seem to want to use sexuality as a way to divide the population along partisan lines. It really is unfortunate.
Also yeah, the butt is the holy the grail of the modern world. (Descan, would you be interested in PMing me about your worship of the booty?)
