All of my friends and work colleagues know. I talk freely about the people I'm dating, and I even hired one for a temp position at work. People sometimes think I'm crazy, but I've never encountered any hostility or real disapproval.
My family knows I'm bisexual and that the man and I have an open relationship, but I don't know if they could wrap their heads around poly
At this point, I don't have an OSO who would want to participate in family gatherings anyway, so it hasn't really come up. But if it did, I know they would be kind to that person, even if they didn't understand what I was doing.
I'm super lucky, because I've never felt anything but loved by my family, even though I'm the unconventional weird one
They might not approve of my choices, but more because they're afraid I might get hurt.
