It could be worded that way. I've always been Poly-but I never knew the word.
When I found the term, I figured out that it described me.
THEN I "came out" to Maca. Really there was no "coming out" beyond that. Even that was more of a "what is the word for who you already know I am".
I was already living my life a certain way-and everyone either thought "wow she's a whore" or "well that's just LR".......
But-to what you were saying, you can use coming out as the meaning.
We were discussing was it worth the changes we made to our lives to Live honestly and truly and forthrightly instead of me cheating-which is what we had before. A sham of a marriage where I was cheating with GG on the side....
