Are you talking about coming out
"hey I am poly/open and accept other partners"
"hey this is bob, he is my secondary etc"
Officially I am open to almost everyone, most people know i am in an open relationship, even some (lets say 50%) of my family. I won't start talking about a potential partner until we are past that initial dating stage. Same when I was single, I did not introduce my family to gf's in the first part of the relationships then either....
When my wife gets called a "slut"...she says thank you...as an fyi
